An interaction device for a demand response from a low-voltage user includes: an electrical circuit, a mechanical switch, a protection module, a data acquisition module, a control processor, a power supply module, a communication module, a load determination module, a blockchain module, and a demand response module. The mechanical switch is connected to the electrical circuit. The protection module is electrically connected to the mechanical switch. The control processor is electrically connected to the protection module. The load determination module, the blockchain module, and the demand response module are electrically connected to the control processor. The data acquisition module is connected to the electrical circuit, and is configured to transmit data to the control processor. The communication module and the power supply module are electrically connected to the control processor.

A method for an interaction device for a demand response from a low-voltage user includes the following operations.

The mechanical switch is automatically turned off in an abnormal situation. The mechanical switch is connected to the electrical circuit at an indoor entrance of a distribution line of the low-voltage user. The mechanical switch is automatically turned off in the abnormal situation based on a control signal from the protection module, or is manually turned off locally or remotely.

The protection module receives a protection signal from the control processor, and controls the mechanical switch to be turned off by using a control signal.

The data acquisition module acquires information of a distribution line, processes a signal including the information of the distribution line, and transmits the processed signal to the control processor. The data acquisition module acquires a current signal, a voltage signal, and a temperature signal of the distribution line, converts an analog signal to a digital signal by using a signal processing circuit, and transmits the digital signal to the control processor.

The control processor processes data from the data acquisition module, and provides data for the protection module, the load determination module, the blockchain module, and the demand response module.

The power supply module supplies power to the control processor.

The communication module is configured to perform data transmission with an external platform.

The load determination module intelligently determinates the type of an electrical appliance used by the user based on a voltage curve and a current curve, and determines demand response potential of the user through comparison and analysis.

The demand response module is configured to process demand response information and to provide a demand response strategy for the user. The demand response module is further configured to process the demand response information and provide a personalized demand response strategy for the user based on the demand response potential of the user.

The blockchain module is configured to credibly record service data in the demand response from the user, and to automatically perform settlement on the demand response according to a smart contract.

The load determination module determines the type of the electrical appliance used by the user and determines the demand response potential of the user through comparison and analysis by:

• • decomposing a load curve of the low-voltage user based on a load determination result by using the following equation:

$P_t=\sum _{k-1}^K{p}_{k,t}+p_{other,t}$

• • where P_t represents a total load power of the low-voltage user at a time instant t, P_k,t represents a power of a k-th type of electrical appliance of the low-voltage user at the time instant t, K represents the number of types of electrical appliances, k ranges from 1 to K, and P_other,t represents a power of other consumption loads of the low-voltage user at the time instant t; and
  • calculating the demand response potential of the low-voltage user based on regulation coefficients of various loads by using the following equation:

$Q_t=\sum _{k=1}^K{x}_k{p}_{k,t}$

• • where Q_t represents a power of an adjustable load of the low-voltage user at the time instant t, x_k represents a regulation coefficient of the k-th type of electrical appliance and ranges from 0 to 1. In a case that the k-th type of electrical appliance is an interruptible load, x_k is equal to 1. In a case that the k-th type of electrical appliance is a completely unregulated load, x_k is equal to 0.

A district terminal serves as a main node of the demand response transaction sub-chain of the district. District terminals, major industrial and commercial users, and measurement automation main stations form a demand response transaction main-chain.
