| Abstract: | Optimal power flow (OPF) is an ideal tool for solving many problems, such as spot pricing, congestion management, and available transfer capability calculation, in an electricity market. This paper presents a novel algorithm for the OPF problem based on a trust region method. The algorithm successively solves linear programming subproblems. Linear step size is adjusted by using the trust region method. A primal dual interior point method with multiple centrality corrections is applied to solving the linear programming subproblems. To improve the stability of the OPF algorithm, a physical strategy is used. Numerical results of a power system of 662 buses show that the algorithm is fast and robust, suitable to real time applications. This project is supported by National Natural Science Foundation of China (No.50079006). |
