摘要：
Based on time domain simulation analysis method, through observing and comparing the trajectories, under frequency load shedding (UFLS) is compared with under frequency pump shedding (UFPS) in their performance and effectiveness. Then UFLS and UFPS scheme setting methods are proposed. The coordination and optimization method between UFLS and UFPS is firstly proposed. The proposed method is verified through case studies, and the results show that this method is effective and feasible. © 2012 State Grid Electric Power Research Institute Press.
