One or more example embodiments relate to a method of generating an energy map and an apparatus using the same.
As global warming and the severity of environmental pollution have gradually increased, people have come to appreciate the need for energy savings and greenhouse gas reduction around the world. To replace existing fossil fuels, various renewable energy sources such as solar light, solar heat, wind, geothermal, and other renewable energy have been proposed, and many investments and research activities are under way due to strong government support in the US and Europe including Korea.
Current power infrastructure is produced centrally through hydropower, thermal power, and nuclear power, and is then transmitted, transformed, and distributed. Recently, with the recognition of the deterioration of some electric power infrastructure and the recognition of the necessity of new and renewable energy, there is a need for a completely different electric power infrastructure. For example, there are families that install solar panels to supply energy or sell power to utility companies.
As such, although new energy is secured through various energy sources, the importance of efficient energy management is growing due to limited resources. Efficient energy management not only means cost savings but also estimating and preparing energy generation and energy consumption by identifying factors that may affect energy and predicting future behavior patterns through historical data.

Referring to
The controller 220 may calculate a weight of the plurality of energy information data. The weight may include at least one of a sequential weight, an AND weight, an OR weight, an XOR weight, a timer weight, a racing weight, a voting weight, and a sum weight.
In this example, the controller 220 may set a sequential weight for the sequentially occurring energy information data, to be 1. When first energy information data is generated and second energy information data is sequentially is generated, a sequential weight for the second energy information data of the first energy information data may be defined as 1. In this example, a sequential weight for the first energy information data of the second energy information data may be defined as −1.
For example, when the energy event A occurs and the specific situation sequentially occurs, the controller 220 may set a sequential weight for the specific situation of the energy event A to be 1. Likewise, the controller 220 may seta sequential weight for the specific situation of the energy event B to be 1, set a sequential weight for the specific situation of the energy event D to be 1, and set a sequential weight for the specific, situation of the energy event G to be 1.
When the energy event C occurs and the energy event L sequentially occurs, the controller 220 may set a sequential weight for the energy event L of the energy event C to be 1. Likewise, the controller 220 may set a sequential weight for the energy event K of the energy event to be 1. In this example, when the energy event K occurs and the specific situation sequentially occurs, the controller 220 may set a sequential weight for the specific situation of the energy event K to be 1.
When the specific situation occurs and the energy event H sequentially occurs, the controller 220 may set a sequential weight for the energy event H of the specific situation to be 1. Likewise, the controller 220 may set a sequential weight for the energy event I of the specific situation to be 1. In this example, when the energy event I occurs and the energy event J sequentially occurs, the controller 220 may set a sequential weight for the energy event J of the energy event I to be 1.
The controller 220 may initially set 0 for other weights.
The controller 220 may set an AND weight for the energy information data sequentially generated under an AND condition to be 1. When the first energy information data and the second energy information data are generated and the third energy information data is sequentially is generated, an AND weight for the first energy information data and the second energy information data of the third energy information data may be defined as 1.
The controller 220 set an OR weight for the energy information data sequentially generated under an OR condition to be 1. When the first energy information data or the second energy information data is, generated and the third energy information data is sequentially generated, an OR weight for the first, energy information data and the second energy information data of the third energy information data may be defined as 1.
The controller 220 set an XOR weight for the energy information data sequentially generated under an XOR condition to be 1. When one of the first energy information data and the second energy information data is generated and the other is not generated, and the third energy information data is sequentially generated, an XOR weight for the first energy information data and the second energy information data of the third energy information data may be defined as 1.
The controller 220 may set a timer weight for the energy information data sequentially generated at preset time intervals. When the first energy information data is generated and the second energy information data is sequentially generated after a first time elapses, a timer weight for the second energy information data of the first energy information data may be defined as the first time.
When later energy information data is generated based on a value of earliest energy information data, the controller 220 may set a racing weight to be 1. When the first energy information data and the second energy information data are generated, and the third energy information data is sequentially generated based on a value of energy information data generated earlier between the first energy information data and the second energy information data, a racing weight for the first energy information data and the second energy information data of the third energy information data may be defined as 1.
When later energy information data is generated based on a value of energy information data that is the most frequently generated, the controller 220 may set a voting weight to be 1. When the first energy information data, the second energy information data, and the third energy information data are generated and fourth energy information data is sequentially generated based on a value of energy information data that is the most frequently generated among a value of the first energy information data, a value of the second energy information data, and a value of the third energy information data, a voting weight for the first energy information data, the second energy information data, and the third energy information data of the fourth energy information data may be defined as 1.
When later energy information data is generated based on a sum of values of energy information data, the controller 220 may set a sum weight to be 1. When the first energy information data, the second energy information data, and the third energy information data are generated and the fourth energy information data is sequentially generated in response to a sum of a value of the first energy information data, a value of the second energy information data, and a value of the third energy information data being greater than or equal to a threshold, a sum weight for the first energy information data, the second energy information data, and the third energy information data of the fourth energy information data may be defined as 1.
Also, the controller 220 may calculate the weight based on a priority. In terms of the weight, the sequential weight, the AND weight, the OR weight, the XOR weight, the timer weight may have priority levels in a descending order. The timer weight, the racing weight, the voting weight, and the sum weight may have a same priority level.
When overlapping weights of the energy information data are generated, the controller 220 may calculate a weight having a higher priority level. For example, when the first energy information data is generated and, the second energy information data is sequentially generated, the controller 220 sets a sequential weight for the first energy information data of the second energy information data to be 1. Also, when the third energy information data is generated and the second energy information data is sequentially generated, the controller 220 may set a sequential weight for the third energy information data of the second energy information data to be 1. In this example, when the first energy information data and the third energy information data are simultaneously generated to generate the second energy information data, the controller 220 may set an AND weight for the first energy information data and the third energy information data of the second energy information data to be 1. As described above, the AND weight may have a higher priority level than that of the sequential weight.
With reference to
The controller 220 may determine a correlation of the energy event L with respect to the energy event A, the energy event B, and the energy event C to be a voting relationship.
The controller 220 may determine a correlation of the energy event H with respect to the specific situation to be a sequential relationship. Likewise, the controller 220 may determine a correlation of the energy event K with respect to the energy event F to be the sequential relationship.
The controller 220 may determine a correlation of the energy event I with respect to the energy event L, the energy event E, the energy event D, and the energy event K to be a sum relationship of an OR relationship between the energy event L and the energy event E and an AND relationship between the energy event D and the energy event K. That is, when the energy event D and the energy event K occur, and the energy event L or the energy event E occurs, the energy event I may sequentially occur in response to a sum of a value of the energy event L or a value of the energy event E, a value of the energy event D, and a value of the energy event K being greater than a threshold.
The controller 220 may determine a correlation of the energy event J with respect to the energy event I to be the voting relationship. For example, the energy event I may sequentially occur after a second time elapses from an occurrence of the energy event I. In this example, the second time may be a timer weight for the energy event I of the energy event J.
An operation of the controller 220 calculating the weight may be as shown in Table 1 below.
