储热参与电网调峰的技术及商业模式分析OACSTPCD

The conventional operation mode of"power determined by heat"employed by thermal power plants,along with the randomness and volatility of new energy power generation,constrains the peak regulation capacity.The incorporation of thermal storage technology into grid peak regulation can optimize the allocation capacity of the energy system.The fundamental principles,appropriate materials,advantages,disadvantages,and future develop-ment trends of three different thermal storage technologies,namely,sensible heat storage(SHS),latent heat stor-age(LHS)and chemical energy storage(CES),are introduced.Furthermore,the strategies of different thermal storage technologies for power system peak regulation at home and abroad as well as the applications of actual peak regulation projects are discussed.Given the special working conditions faced by thermal storage technology in power grid peak regulation,four critical evaluation criteria,including safety,performance matching,reliability and economy that must be considered for thermal storage technology to participate in power grid peak regulation are pro-posed.The main business models,including energy management contracting(EMC),two-part tariff(TPT),and ancillary service market(ASM)for thermal storage to participate in power trading are explored.These models serve as valuable references for enabling the widespread commercial operation of thermal storage technology within the context of grid peak regulation.
