Real-time Security Verification Method for China Southern Regional Frequency Regulation Market Including Third-party Independent Entities
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.
