摘要：
In this paper, a novel temperature-dependent optimal power flow (TDOPF) is proposed to improve conventional optimal power flow (OPF). In conventional OPF, the resistance of branches is assumed to be constant and temperature effects on line resistance has been neglected, which will result in a great deviation with actual operation situation. Based on the weak coupling property of electrical and thermal variables, the de coupled TDOPF is proposed to improve the efficiency of TDOPF algorithm. All the OPF algorithms are sufficiently solved by a novel simplified primal-dual interior point method. Finally, it is shown by the numerical simulation results that the proposed TDOPF and its decoupling algorithm are available and effective.
