摘要
Branch flow model is a scheduling model considering power flow. It is nonconvex and NP-hard. In order to solve the model quickly and convergently, we can relax the model into a convex optimization model by using the convex relaxation strategy. In this paper, we propose that under certain conditions, the two models before and after convex relaxation can be guaranteed to have the same optimal solution. So we can solve the convex optimization model which is easier to solve.
