Abstract

This paper investigated an optimal method of optimal power flow in large 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 subproblems of multi regions, which is a quadratic programming problem used to solve a DC optimal power flow. The optimal convergence condition of multi-region is discussed. The interchange information among regions is export price and boundary nodal bus phase angle. The IEEE RTS-96 with two and three interconnected regions is studied to illustrate the effect of the proposed approach and to prove a great future in interconnected power system
