The present application claims priority to Chinese Patent Application No. 202210245141.4, titled “LOW-VOLTAGE USER INTELLIGENT INTERACTION RESPONSE EXCHANGE SYSTEM AND METHOD”, filed on Mar. 14, 2022 with the Chinese Patent Office, which is incorporated herein by reference in its entirety.
The present disclosure relates to the field of demand response of low-voltage users, and in particular to a response interaction system for intelligently interacting with a low-voltage user and a response interaction method for intelligently interacting with a low-voltage user.
Demand response is an important way to improve flexibility of a power system, facilitating realizing the dual-carbon target and constructing a new type of power system. According to the conventional technology, users that participate in the demand response are only industrial users. With the development of Internet of Things technology, residential loads may participate in the demand response. Residential loads are high-quality and flexible adjustable resources, so that participation of the residential loads in low-voltage demand response is conducive to increasing the users participating the demand response and further improving the total amount of available scheduling resources.
Based on an incentive pattern of affecting a load, the demand response may include a price-based demand response and an incentive-based demand response. For the price-based demand response, an end power consumer is guided to independently adjust electricity consumption and electricity consumption time based on a price signal. For the incentive-based demand response, the end power consumer is encouraged to reduce a load through economic compensation and electricity price rebates. Based on the demand response, adjustability of a load side of the power system can be significantly improved, thereby improving the operation efficiency of the power system, optimizing investment and construction, enhancing the new energy consumption capacity, and flattening the load curve.
Currently, power grid corporations eagerly hope that the low-voltage users participate in the demand response to enhance the energy consumption capacity, and the low-voltage users may obtain economic benefits from participating in the demand response. However, at present, the low-voltage users do not enthusiastically participate in the demand response, mainly due to the fact that it is not convenient for residential loads to participate in the low-voltage demand response. Usually, it is required for the residential user to download multiple APPs (applications) to receive demand response information. In addition, APPs released for the demand response in different regions are not the same or unified. Furthermore, after obtaining the demand response information, it is required for the residential user to perform relevant operations to realize the demand response. However, due to factors such as publicity, the residential user is prone to erroneously operate, resulting in failure of the demand response and even electricity accidents.
A response interaction system for intelligently interacting with a low-voltage user and a response interaction method for intelligently interacting with a low-voltage user are provided according to the present disclosure, to solve the problem of inconvenient and prone to misoperation for the low-voltage user in participating in power demand response according to the conventional technology.
