Abstract:
Power flow calculation is fundamental and essential in power system design, planning and operation. The existing power flow calculation methods usually handle the generator reactive power limits with switching heuristics and suffer from low efficiency and convergence. To resolve the problem, this paper proposes an efficient power flow calculation method, where the reactive power limits of PV nodes are modeled by smooth complementary constraints. First, the constraints of the PV node's reactive power limits are handled by the smooth and approximate Fischer-Burmeister function. Based on this, a satisfactory power flow model is obtained. Then, to solve this model, an efficient and modified fast decoupled power flow algorithm is presented. Test results of many large-scale test systems show the validity, convergence and efficiency of the proposed method.
