According to an embodiment of the present disclosure, technology related to adjusting electric power supply and demand is improved.
In the accompanying drawings:
Hereinafter, an embodiment of the present disclosure will be described.
The electric power grid 1 is, for example, a microgrid. The microgrid is a mechanism for local production and local consumption of energy by grouping energy supply sources and consumption facilities within a certain range. Distributed power sources such as photovoltaic or wind power are used as the source of energy. A microgrid stably adjusts the electric power supply and demand by installing the small-scale power generation facility 20 near electricity consumers and using distributed power sources.
The power company 2 supplies power to the electric power grid 1. The power company 2 enters into an electricity supply contract with a consumer of power in advance and supplies the consumer with planned electrical energy every predetermined period of time (e.g., monthly).
The control apparatus 10 is, for example, a computer such as a server apparatus. The control apparatus 10 is communicably connected to the power generation facility 20, the power storage facility 30, the consumer facility 40, and the power receiving and transforming facility 50 via the communication network 4.
Power generation facilities 20 are “distributed power sources” that convert renewable energy into electricity, for example, photovoltaic generators, thermal storage generators, or wind turbines. The power generation facility 20 is connected to the power storage facility 30 and the power receiving and transforming facility 50 by the power cable 3. In this disclosure, the power generation facility 20 includes a thermal storage facility that converts heat stored in a thermal storage tank into electricity to generate power of thermal energy storage. The power generation facility 20 transmits the generated electricity to the power storage facility 30 or the power receiving and transforming facility 50 via the power cable 3. The power generation facility 20 is communicably connected to the control apparatus 10 via the communication network 4.
The power storage facility 30 is a storage battery that stores electricity supplied by the power company 2 or electricity generated by the power generation facility 20 and discharges the stored electricity. The power storage facility 30 charges electricity transmitted from the power receiving and transforming facility 50 or the power generation facility 20 via the power cable 3 and discharges the charged electricity to the power receiving and transforming facility 50. The power storage facility 30 is communicably connected to the control apparatus 10 via the communication network 4.
The consumer facilities 40 are buildings, condominiums, public facilities (e.g., schools), stores, or residences, and are equipped with electrical appliances that consume power, such as air conditioning equipment and lighting fixtures. The consumer facilities 40 receive power distribution from the power receiving and transforming facilities 50 via the power cables 3. The consumer facility 40 is communicably connected to the control apparatus 10 via the communication network 4.
The power receiving and transforming facilities 50 accept high-voltage electricity supplies distributed from the power company 2, transform them, and distribute them to various devices within the area of the electric power grid 1. The power receiving and transforming facilities 50 distribute electricity that the power storage facilities 30 are controlled to charge. The power receiving and transforming facilities 50 convert electricity to a voltage that can be used by the consumer facilities 40 and distribute electricity to the consumer facilities 40. The power receiving and transforming facility 50 is communicably connected to the control apparatus 10 via the communication network 4.
The control apparatus 10 of the present embodiment controls the power storage facility 30 to charge power at a first adjustment amount corresponding to a difference that occurs when planned electrical energy exceeds actual electrical energy, control the power generation facility 20 to generate power at a second adjustment amount corresponding to a difference that occurs when the first adjustment amount exceeds electrical energy that the power storage facility 30 has been controlled to charge, control the power generation facility 20 to generate power at a third adjustment amount corresponding to a difference that occurs when the planned electrical energy is equal to or less than the actual electrical energy, and control the power storage facility 30 to discharge power at a fourth adjustment amount corresponding to a difference that occurs when the third adjustment amount exceeds electrical energy that the power generation facility 20 has been controlled to generate.
Thus, according to the present embodiment, charging of the power storage facility 30 is prioritized in order to adjust electric power supply and demand. Therefore, even in a situation where discharge from the power storage facility 30 is required, the power generation facility 20 is first required to generate power within its generating capacity, and if the power supply and demand still cannot be adjusted, the power storage facility 30 is required to discharge the power. Therefore, the technology for adjusting power supply and demand is improved in that the probability of adjusting power supply and demand even when the output of major power sources, such as solar power generators, plummets is increased.

The power receiving and transforming facility 50 includes a power transformer 51, a communication interface 52, and a controller 53. The power receiving and transforming facilities 50 serve as the entrance (gate) for the power company 2 to transmit (sell) the planned electrical energy to the electric power grid (microgrid) 1.

The power transformer 51 receives the actual electrical energy supply from the power company 2. The power transformer 51 steps down the high-voltage electricity supplied by the power company 2 and distributes it to the power generation facilities 20, the power storage facilities 30, and the consumer facilities 40 connected by the power cable 3 within the area of the electric power grid 1.

In the present embodiment, the power receiving and transforming facility 50 communicates with the control apparatus 10 via the communication interface 52 and the communication network 4. The communication interface 52 routinely notifies the control apparatus 10 of the state of electricity supply and demand in the area of the electric power grid 1.
The controller 53 includes at least one processor, at least one programmable circuit, at least one dedicated circuit, or a combination of these. The controller 53 controls operations of the entire power receiving and transforming facility 50. The controller 53 routinely notifies the control apparatus 10 of the actual electrical energy supplied by the power company 2 via the communication interface 52 and the communication network 4. The controller 53 controls the actual electrical energy supplied by the power company 2 to be supplied to equipment within the area of the electric power grid 1, and furthermore, if there is a surplus electrical energy, it is charged to the power storage facility 30 via the power transformer 51.
In steps S101-S102, the controller 13 calculates the overall adjustment amount W0, which is the difference between the planned electrical energy Wplan and the actual electrical energy Wact, and performs a supply-demand judgment step to determine whether the overall adjustment amount W0 exceeds 0 kWh.
Step S101: The controller 13 calculates the overall adjustment W0 by subtracting the actual electrical energy Wact from the planned electrical energy Wplan.
The planned electrical energy Wplan is the amount of electrical energy supplied to the electric power grid 1 within a given period (e.g., monthly) based on the power supply plan (contract) between the consumer and the power company 2. The actual electrical energy Wact is the electrical energy actually supplied to the electric power grid 1 from the power company 2. The overall adjustment amount W0 is the difference between the planned electrical energy Wplan and the actual electrical energy Wact, and is obtained by the following formula (1). The controller 13 acquires the planned electrical energy Wplan from the memory 12. The controller 13 acquires the actual electrical energy Wact from the power receiving and transforming facility 50 via the communication interface 11 and the communication network 4. The units for the planned electrical energy Wplan, actual electrical energy Wact, and overall adjustment W0 are kWh.
Step S102: The controller 13 determines whether the overall adjustment W0 is greater than 0 kWh. If the overall adjustment W0 is greater than 0 kWh, proceed to step S103; if the overall adjustment W0 is equal to or less than 0 kWh, proceed to step S106.
If the overall adjustment W0 is greater than 0 kWh, a further supply of electrical energy from the power company 2 is expected.
In steps S103 to S105, the controller 13 performs the power storage step to control the power storage facility 30 to charge power at the first adjustment amount W1 corresponding to the difference that occurs when the planned electrical energy Wplan exceeds the actual electrical energy Wact, and to control the power generation facility 20 to generate power at the second adjustment amount W2 corresponding to the difference that occurs when the first adjustment amount W1 exceeds the electrical energy that the power storage facility 30 has been controlled to charge. For convenience, the overall adjustment amount W0 when the overall adjustment amount W0 is greater than 0 kWh is referred to as the first adjustment amount W1, and the overall adjustment amount W0 when the overall adjustment amount W0 is less than 0 kWh is referred to as the third adjustment amount W3.
Step S103: If the first adjustment amount W1 is 0 kWh or more, the controller 13 sets the first adjustment amount W1 to the target value and controls the power storage facility 30 to charge power.
The controller 13 sets the first adjustment amount W1 to the target value and controls the power storage facility 30 to charge the power.
If the first adjustment amount W1 exceeds 0 kWh, the controller 13 controls the power storage facility 30 to charge the power within the power storage capacity of the power storage facility 30 by setting the first adjustment amount W1 to the target value.
Step S104: The controller 13 determines whether the second adjustment amount W2, which is the first adjustment amount W1 minus the electrical energy that the power storage facility 30 has been controlled to charge, exceeds 0 kWh. If the second adjustment amount W2 is greater than 0 kWh, proceed to step S105; if the second adjustment amount W2 is equal to or less than 0 kWh, the process ends.
The second adjustment amount W2 is the difference between the first adjustment amount W1 and the electrical energy What that the power storage facility 30 has been controlled to charge, and is obtained by the following formula (2). The controller 13 acquires electrical energy Wbat from the power storage facility 30 via the communication interface 11 and the communication network 4. The unit of the electrical energy Wbat and the second adjustment amount W2 is kWh.
If the second adjustment amount W2 is 0 kWh or a negative value, the controller 13 terminates the process without controlling the power generation facility 20 to generate power. This is because there is no electrical energy that allows the power generation facility 20 to generate power on the electric power grid 1.
Step S105: When the second adjustment amount W2 exceeds 0 kWh, the controller 13 sets the second adjustment amount W2 to the target value and controls the power generation facility 20 to generate power.
If the second adjustment amount W2 is greater than 0 kWh, the controller 13 sets the second adjustment amount W2 to the target value and controls the power generation facility 20 to generate power within the power generation capacity of the power generation facility 20. In this disclosure, the power generation facility 20 shall include a thermal storage facility that converts heat stored in a thermal storage tank into electricity to generate power of thermal energy storage.
In steps S106 to S108, the controller 13 performs a power discharge step in which the controller 13 controls the power generation facility 20 to generate power at the third adjustment amount W3 corresponding to the difference that occurs when the planned electrical energy Wplan is equal to or less than the actual electrical energy Wact and controls the power storage facility to discharge power at the fourth adjustment amount W4 corresponding to the difference that occurs when the third adjustment amount W3 exceeds the electrical energy that the power generation facility 20 has been controlled to generate.
Step S106: The controller 13 sets the absolute value of the third adjustment amount W3 to the target value and controls the power generation facility 20 to generate power.
If the overall adjustment W0 is equal to or less than 0 kWh, no further supply of electrical energy is expected from the power company 2. In such cases, discharge from the power storage facility 30 is generally required to adjust the power supply and demand. However, in the present disclosure, the controller 13 controls the power generation facility 20 to set the absolute value of the third adjustment amount W3 to the target value and to generate power within the power generation capacity of the power generation facility 20 before controlling the power storage facility 30 to discharge the power. The “absolute value” of the third adjustment amount W3 is stated here because the value of the third adjustment amount W3 is negative. The controller 13 controls the power generation facility 20 to generate power to make up for the shortfall in the power supply.
Step S107: The controller 13 determines whether the fourth adjustment amount W4, which is the absolute value of the third adjustment amount W3 minus the absolute value of the electrical energy that the power generation facility 20 has been controlled to generate, exceeds 0 kWh. If the fourth adjustment amount W4 is greater than 0 kWh, proceed to step S108; if the fourth adjustment amount W4 is equal to or less than 0 kWh, the process ends.
The fourth adjustment amount W4 is the difference of the absolute value of the third adjustment amount |W3| minus the absolute value of the electrical energy generated by the power generation facility 20, |Wgen|, and is obtained by the following formula (3). The controller 13 acquires electrical energy Wgen from the power generation facility 20 via the communication interface 11 and the communication network 4. The unit of the electrical energy Wgen and the fourth adjustment amount W4 is kWh.
If the fourth adjustment amount W4 is 0 kWh or a negative value, the controller 13 terminates the process without controlling the power storage facility 30 to discharge power. This is because the shortfall in power supply in the electric power grid 1 was compensated for by power generation.
Step S108: When the fourth adjustment amount W4 exceeds 0 kWh, the controller 13 sets the fourth adjustment amount W4 to the target value and controls the power storage facility 30 to discharge power.
As described above, the controller 13 sets the absolute value of the third adjustment amount W3 to the target value and controls the power generation facility 20 to generate power within the power generation capacity of the power generation facility 20 before controlling the power storage facility 30 discharge the power from the power storage facility 30. However, if the fourth adjustment amount W4 exceeds 0 kWh, that is, if the power supply is still insufficient even though the power generation facility 20 has generated power, the controller 13 controls the power storage facility 30 to discharge the power by setting the fourth adjustment amount W4, which corresponds to the shortfall, to the target value.
In step S109 to step S110, the controller 13 performs a power consumption step in which the controller 13 controls the consumer facility 40 to consume power at the fifth adjustment amount W5 corresponding to the difference that occurs when the second adjustment amount W2 exceeds the electrical energy that the power generation facility 20 has been controlled to generate.
Step S109: After executing the power storage step, the controller 13 determines whether the fifth adjustment amount W5, which is the second adjustment amount W2 minus the electrical energy Wgen that the power generation facility 20 has been controlled to generate, exceeds 0 kWh.
The fifth adjustment amount W5 is the difference between the second adjustment amount W2 and the electrical energy Wgen that the power generation facility 20 has been controlled to generate, and is obtained by the following formula (4). The unit for the fifth adjustment amount W5 is kWh.
If the fifth adjustment amount W5 is 0 kWh or a negative value, the controller 13 terminates the process without controlling the consumer facilities 40 to promote power consumption. This is because there is no electrical energy that controls the consumer facilities 40 to consume power on the electric power grid 1.
Step S110: When the fifth adjustment amount W5 exceeds 0 kWh, the controller 13 sets the fifth adjustment amount W5 to the target value and controls the consumer facilities 40 to promote the power consumption.
The state in which the fifth adjustment amount W5 exceeds 0 kWh is a state in which there is still room for power supply even after controlling the power storage facility 30 to store power within power storage capacity and controlling the power generation facility 20 to generate power within power generation capacity. Therefore, the controller 13 adjusts the power supply and demand by controlling the consumer facilities 40 to promote the operation of air conditioning equipment or lighting fixtures, etc.
In step S111 to step S112, the controller 13 performs the power consumption suppression step to control the consumer facility 40 to suppress power consumption at the sixth adjustment amount W6 corresponding to the difference that occurs when the fourth adjustment amount W4 exceeds the electrical energy that the power storage facility 30 has been controlled to discharge power.
Step S111: After executing the power discharge step, the controller 13 determines whether the sixth adjustment amount W6, which is the absolute value of the third adjustment amount W3 minus the absolute value of the electrical energy Wdis that the power storage facility 30 has been controlled to discharge, exceeds 0 kWh.
The sixth adjustment amount W6 is the difference between the absolute value of the third adjustment amount W3, |W3|, and the absolute value of the electrical energy Wdis, |Wdis|, that the power storage facility 30 has been controlled to discharge, and is obtained by the following formula (5). The controller 13 acquires the amount of electrical energy Wdis from the power storage facility 30 via the communication interface 11 and the communication network 4. The unit of the electrical energy Wdis and the sixth adjustment amount W6 is kWh.
If the sixth adjustment amount W6 is 0 kWh or a negative value, the controller 13 terminates the process without controlling the consumer facilities 40 to suppress power consumption. This is because the shortfall in power supply in the electric power grid 1 was compensated for by power generation and power discharge.
Step S112: When the sixth adjustment amount W6 exceeds 0 kWh, the controller 13 sets the sixth adjustment amount W6 to the target value and controls the consumer facility 40 to suppress power consumption.
When the sixth adjustment amount W6 exceeds 0 kWh, the power supply is still insufficient even if the power generation facility 20 is controlled to generate power within power generation capacity and the power storage facility 30 is controlled to discharge power within power storage capacity. Therefore, the controller 13 adjusts the power supply and demand by controlling the consumer facility 40 to suppress the operation of air conditioning equipment, lighting fixtures, and other equipment.
When introducing power generated by photovoltaic generators into the electric power grid 1, if the output of a photovoltaic generator suddenly drops due to changes in weather conditions, it may take time for other generators in the area of the electric power grid 1 to complete start-up and interconnection, which may not fully compensate for the sudden drop in output of the photovoltaic generator. For example, when the weather is clear during the day, the output of a photovoltaic generator is high, but when cumulonimbus clouds cover the sun, the output plummets. In such a case, as illustrated in
In this respect, the control apparatus 10 of the present embodiment controls the power storage facility 30 to charge power at the first adjustment amount W1 corresponding to the difference that occurs when the planned electrical energy Wplan exceeds the actual electrical energy Wact, controls the power generation facility 20 to generate power at the second adjustment amount W2 corresponding to the difference that occurs when the first adjustment amount W1 exceeds the electrical energy that the power storage facility 30 has been controlled to charge, controls the power generation facility 20 to generate power at the third adjustment amount W3 corresponding to the difference that occurs when the planned electrical energy Wplan is equal to or less than the actual electrical energy Wact, and controls the power storage facility 30 to discharge power at the fourth adjustment amount W4 corresponding to the difference that occurs when the third adjustment amount W3 exceeds the electrical energy that the power generation facility 20 has been controlled to generate. In this way, charging the power storage facility 30, i.e., power storage, is prioritized in order to adjust the power supply and demand. Therefore, even in a situation where discharge from the power storage facility 30 is required, the probability of adjusting power supply and demand even when the output of the main power source, such as a solar power generator, suddenly drops is improved by first controlling the power generation facility 20 to generate power and then controlling the power storage facility 30 to discharge the power when power supply and demand still cannot be adjusted. Thus, technology related to adjusting electric power supply and demand is improved.
While the present disclosure has been described with reference to the drawings and examples, it should be noted that various modifications and revisions may be implemented by those skilled in the art based on the present disclosure. Accordingly, such modifications and revisions are included within the scope of the present disclosure. For example, functions or the like included in each component, each step, or the like can be rearranged without logical inconsistency, and a plurality of components, steps, or the like can be combined into one or divided.

For example, an embodiment in which some or all of the components of the control apparatus 10 are provided in the power generation facility 20, the power storage facility 30, or the consumer facility 40 can also be implemented.
For example, an embodiment in which a general purpose computer functions as the control apparatus 10 according to the above embodiment can also be implemented. Specifically, a program in which processes for realizing the functions of the control apparatus 10 according to the above embodiment are written may be stored in a memory of a general purpose computer, and the program may be read and executed by a processor. Accordingly, the present disclosure can also be implemented as a program executable by a processor, or a non-transitory computer readable medium storing the program.
