Active power dispatch of new energy refers to an effective method ensuring the stable operation and optimal economic benefits systems through scientific rational planning control active output from generation. However, as proportion increases, system’s voltage support capacity decreases, leading potential collapse oscillation issues. The Multiple Renewable Energy Station Short-Circuit Ratio (MRSCR) is a critical indicator for with high penetration. This study aims introduce MRSCR constraints into guarantee sufficient grid integration strength operation. are approximated using least squares fitting method. Additionally, this compares margin indicators between wind thermal scheduling models without considering MRSCR. Case studies show that model improves minimal loss benefits.
