Research on Demand Side Response System of Electricity Price Under Electricity Market Incentive Mechanism

Abstract

Aiming at the traditional day-ahead dispatching scheme of power generation,the paper proposes a power system security optimization dispatching modelthat considers the demand response of electricity prices under the electricitymarket incentive mechanism. Based on the peak and valley time-of-use elec-tricity price, the paper establishes an incentive compensation mechanism toencourage users to be active. Participating in demand-side resource schedul-ing makes the effect of “peak shaving and valley filling” more pronounced.Simultaneously, to rationally configure the reserve capacity of grid operation,the system incorporates the expected power outage loss into the proposedmodel to ensure the grid operation safety. The analysis of calculation exam-ples based on IEEE24 nodes shows that the power optimal dispatch modelproposed in the paper considering demand response and expected outage loss can reduce the operating cost of the power grid under the premise of ensuringa certain level of reliability and realize the economy of the power system inthe market environment and safe operation.
