Abstract
This paper investigated an optimal method of optimal power flow in large scale interconnected power grids. A decomposition collaborative model based on partial duality is analyzed, and a parallel algorithm based on DC optimal power flow model is presented in multi-region decomposition of interconnected power grids. The OPF computation of large power grid is decomposed into multi regions subproblems, which is a quadratic programming problem used to solve a DC optimal power flow. The condition of multi-region optimal convergence is discussed. The information of interchanging between regions is export price and boundary nodal bus phase angle. The IEEE RTS-96 systems with two, three and four interconnected regions are studied to illustrate the effect of the proposed approach and prove to have a great future in real time OPF computation of interconnected power system.
