考虑多场站短路比约束的新能源电力系统经济安全调度方法
An economic and secure dispatch method for renewable energy power systems con-sidering MRSCR constraints
摘要
Abstract
The increasing installed renewable energy capacity in power systems poses unprecedented challenges to dynamic stability and voltage support capability.Multiple renewable energy stations short circuit ratio(MRSCR)has emerged as a critical indicator for evaluating voltage support strength in renewable-rich power systems.This pa-per first investigates an online MRSCR calculation method based on a complex graph neural network(GNN)model.Subsequently,real-time MRSCR constraints are incorporated into a renewable generation dispatch optimization model,and a solution approach for handling complex MRSCR constraints.Finally,case studies are conducted to analyze and verify the proposed dispatch method considering MRSCR constraints.The results demonstrate that the proposed dispatch method effectively prevents the system voltage support strength from falling below critical thresh-olds due to renewable power fluctuations,thereby ensuring grid operational security.关键词
