Load shedding has been extensively studied for years. It has been used as an important measure for emergency control. This paper shows that the problem is NP-hard and introduce a way to obtain load shedding strategies based on ordered binary decision diagram (OBDD). The advantages of our method include that priority relationships among different loads are explicitly characterized and all solutions that violate static constrains including power balance, priority, and real power flow safety are excluded. This will make search for load shedding schemes that satisfy transient stability much more efficient.
