Problems solved by technology

[0006] Aiming at the defects that the existing grid load transfer method based on time-of-use electricity price has a long feedback period, cannot flexibly respond to grid load changes, and does not consider user response, the main technical problem to be solved by the present invention is: to provide grid enterprises with the aim of reducing grid load , reduce the total power consumption, and fully consider the response of power users, and consider the power grid load transfer scheme that takes into account the interaction process between the power supply and the consumer

Embodiment Construction

[0033] An embodiment of the present invention provides a multi-agent based grid load transfer method under time-of-use electricity prices. Under the framework of the multi-agent system, a method of using time-of-use electricity price to load the load of the power system is proposed, which can be conveniently applied to practical occasions.

[0034] In this embodiment, power users are classified as follows:

[0035] (1) Active users are usually large-scale industrial users in the region, with heavy load, advanced production technology, strong sense of social responsibility, and strong load curve adjustment ability. Electricity costs account for a large proportion of production costs and are sensitive to electricity price adjustments. Participating in demand response is conducive to saving production costs.

[0036] (2) Intermediate users are usually small and medium-sized industrial and commercial users in the region, with large loads and the ability to participate in demand r...

Abstract

The invention discloses a method for transferring power grid loads under time-of-use electricity price based on multiple intelligent bodies. The method comprises the following steps that (1) a power grid load transfer target is set; (2) power consumers are classified, so that the different consumer intelligent bodies are formed; (3) a power grid enterprise intelligent body is set and an electricity price adjustment scheme of the power grid enterprise intelligent body is established; (4) the time-of-use electricity price is set and adjusted by the power grid enterprise intelligent body, electricity price information is released to each power consumer intelligent body, and power consumer load information is received; (5) the electricity price information and load adjustment information of other consumer intelligent bodies are received by each consumer intelligent body, the load of each consumer intelligent body is adjusted, and load information of each consumer intelligent body is transmitted to the power grid enterprise intelligent body; (6) the latest two steps are repeated until the transfer target is completed. According to the method, the power consumers are modeled, so that the consumer intelligent bodies of different types are formed, the uncertainty of the consumer responses and the dynamic change of power utilization characteristics are considered, the time-of-use electricity price is used pertinently to transfer the loads, the power supply efficiency is improved, and the power use mode is optimized.

Description

technical field [0001] The invention relates to the field of demand response time-of-use electricity price, in particular to a multi-agent-based power grid load transfer method under time-of-use electricity price. Background technique [0002] Demand response is the supply side of the power grid that provides price or incentive signals to urge power users to change their electricity consumption patterns, guide users to use less electricity during peak hours, and use more electricity during low valleys, improve power supply efficiency, optimize electricity usage patterns, and achieve energy conservation and environmental protection. long-term purpose. Demand response is divided into price-based demand response and incentive-based demand response. Price-based demand response means that users respond to changes in retail electricity prices and adjust electricity demand accordingly; incentive-based demand response means that demand response implementing agencies formulate deter...
