备用与现货电能量市场模型衔接机制研究
Research on Interconnection Mechanism Between Reserve and Spot Power Markets
摘要
Abstract
The spot electric energy market and reserve market are closely integrated in terms of market organization and clearing model.To study the impact of different integration mechanisms on the overall generation costs,energy-reserve market prices,and other market performance indicators,this paper establishes a joint clearing model for day-ahead electricity-energy and reserve market.Based on the clearing sequence and different objective function cost items at the unit commitment stage,it builds four sequential clearing models.It conducts simulation on the IEEE118 node system to study and analyze the relevant performance indicators of the power market under different integration mechanisms and the reasons for the differences in formation.By changing system parameters and boundary conditions,the paper also studies the feasible clearance domain of the market under different integration mechanisms.The results show that the total generation cost and market electricity price of the joint clearing model are superior,which can better utilize system flexible resources and also have the largest feasible clearance interval.The energy-priority sequential mode,which considers reserve costs comprehensively in unit commitment,ranks second only to the joint clearing model in terms of overall generation costs,market electricity prices,and feasible clearance domains.Finally,according to the simulation and theoretical analysis results,the paper provides construction schemes for short-term sequential mode and long-term joint mode of integrating reserve and spot electricity-energy markets.关键词
