Event-driven electric power system demand response method

Abstract

The invention discloses an event-driven electric power system demand response method. The event-driven electric power system demand response method comprises the following steps: firstly, evaluating different electric power failure events possibly existing according to electric power system basic tides and an electric power system fault list in a power grid dispatching center, judging whether operation reserve capacity is smaller than an expected value or not, determining fault types, and taking the adoption of emergency demand response schemes into account in combination with demand responseuser information; secondly, determining the participated user for demand response and the demand response quantity of each user after correlated constraint conditions are taken into account based on the driving of fault events, and establishing a demand response model in combination with the user action time of demand response and the dynamic model of an electric power system to form the emergencydemand response schemes; then, using time-domain simulation to evaluate the influence of each emergency demand response scheme possibly caused on system operation; and finally, carrying out fine adjustment on each emergency demand response scheme according to the time-domain simulation result of a designed EDRP model so as to form a demand response action table. According to the method, the minimum demand response cost can be realized under the condition that certain operation reserve is guaranteed, so that excessive response of the user is avoided.

Description

technical field [0001] The invention relates to the field of power demand side management, in particular to an event-driven power system demand response method. Background technique [0002] With the increase in demand for electricity due to economic and social development, while the power grid is facing a tight power supply situation, there are also problems with a large number of intermittent renewable energy sources, as well as the huge pressure of system peak regulation and frequency regulation. In addition to seeking solutions from the power supply side, user-side resources should be further explored, especially the integration of small-capacity user resources. Strong demand growth, limited power generation capacity, weak grid infrastructure, and high penetration of renewable energy grid-connected power generation as the main driving forces constitute favorable conditions for implementing demand response on the user side. [0003] The development of demand response pro...

Problems solved by technology

[0004] The introduction of electricity demand response in my country is mainly due to many factors. First, the growth of power peaks or peak-to-valley differences is still continuing, and the frequency of extreme weather is increasing. Service-oriented transformation, as the traditional management mode of mandatory orderly power consumption and power rationing during peak power loads, is no longer suitable for social development
