Based on the framework of substitute power product(SPP)market,this paper focuses on the marketization of regulation capacity and conducts in-depth exploration of the regulating energy trading mechanism and the coordinated bidding method for substitute energy and regulating energy.Firstly,the necessity and theoretical challenges in regulation capacity marketization are analyzed.It is pointed out that under the traditional time-of-use trading mechanism,the regulation capacity is neither separately priced nor easily quantifiable,exhibiting significant negative externalities,which fundamentally constrains the enhancement of regulation capacity in new power systems.Secondly,the formation processes of substitute power products and regulation contributions are unified and summarized as the generation process of regulation demand.A regulation demand formation model,a method for generating system regulation demand curves,and a regulating energy trading clearing mechanism are proposed.Finally,the coordinated bidding process of the SPP spot market based on regulating energy trading is elaborated in detail.This process includes single-round substitute energy trading and multi-round regulating energy trading,with each round cleared according to the equal incremental rate criterion,ensuring the process is simple and transparent.Case studies show that,compared with the traditional time-of-use trading mechanism,the SPP spot market achieves lower electricity purchase costs in the same scenarios and establishes a positive incentive mechanism for system flexibility enhancement through regulating energy trading.
