独立储能参与的电能量和全过程调频市场联合出清模型

An ovcrvicw and analysis of the current Status of energy storage participation in domestic and international electricity markets is provided to address the challcnge posed by the gradual decrease in the Proportion of synchronous resources in the power System affecting System frequency security. Commencing with the genuine need for energy storage to engage in rapid frequency regulation and bolster System frequency security, a derivation is carried out based on a Clearing modcl for the electrical energy and reserve markets with energy storage involvement. This study systematically analyzes the System's frequency response processes with and without energy storage involvements, sets the criteria for energy storage to off er rapid frequency regulation and secondary frequency regulation, creates a Joint Clearing modcl for the electrical energy and reserve markets with independent energy storage participation and the frequency rcgulation ancillary Service market (incorporating fast frequency rcgulation), and cstablishes the pricing mechanisms for electrical energy, operating reserves, rapid frequency rcgulation, and secondary frequency regulation within this modcl. The proposed model encompasses four crucial stages: inertia response, rapid frequency rcgulation, primary frequency rcgulation, and secondary frequency regulation, showeasing the comprehensive frequency security attributes of the power System. The Simulation outcomes reveal that compared to the Joint Clearing model lacking energy storage partieipation, the proposed model reduces System operational expenses by approximately 0. 72% and 0. 47% in the case of the IEEE-30 and NREL-118, rcspcctivcly, thereby fortifying System frequency security while cutting down operational costs.
