摘要
随着南方区域电力市场建设的不断推进,在区域现货市场调电试运行中出现了因机组调频容量调出导致断面越限的案例。为提升安全校核效率,实现调频安全校核流程与现货电能量市场的有效衔接,提出调频辅助服务市场实时安全校核全流程优化策略。文中优化设计了适用于区域电网的精细化断面分类策略,用于快速筛选调频单元封闭类断面、联络类断面以提升安全校核效率。针对不同类型断面,设计了考虑第三方独立储能及可调节负荷的典型调频调出场景,并将随机的自动发电控制(AGC)指令转化为确定性的调频容量调出场景。在此基础上,针对区域现货市场建设中各阶段的不同需求,提出两种调频安全校核与现货市场的衔接路径。最后,根据南方区域调频市场实际运行情况,验证了所提方法的准确性和有效性。
With the continuous promotion of the construction of the China southern regional electricity market,there have been cases of cross-section overlimit due to the dispatch of unit frequency regulation capacity during the trial operation of power regulation in the regional electricity spot market.In order to improve the efficiency of security verification and achieve the effective integration of the frequency regulation security verification process with the electricity spot market,a real-time security verification optimization strategy for the whole process of the frequency regulation auxiliary service market is proposed.A refined cross-section classification strategy suitable for regional power grids is optimized and designed to quickly screen the closed and connected sections of frequency regulation units to improve the security verification efficiency.For different types of cross-sections,typical scenarios for the dispatch of frequency regulation capacity considering third-party independent energy storage and adjustable loads are designed.Random automatic generation control(AGC)instructions are then transformed into deterministic scenarios for the dispatch of frequency regulation capacity.On this basis,two connection paths between the frequency regulation security verification and the electricity spot market are proposed to meet the different needs of different stages in regional electricity spot market construction.Finally,the accuracy and effectiveness of the proposed method are verified based on the actual operation of the frequency regulation market in southern China.
