Distributed Power Flow Calculation Method for Integrated Transmission and Distribution Grid
摘要
Abstract
Due to access of a large number of distributed generations and electric vehicles into power distribution networks, traditional mutually independent power flow calculations for power transmission grid and distribution grid are not suitable any more. In view of that the power transmission grid and the distribution grid are monitored and managed by different con-trol centers,this paper presents a method for integrated distributed power flow calculation for the power transmission and distribution grid based on master-slave-splitting method. This calculation method takes the global power transmission and dis-tribution grid as the research object and divides the problem of integrated power flow into three sub-problems including the transmission grid power flow calculation,power flow calculation for multiple distribution grids and boundary node coordina-tion. Newton method and the forward-backward sweep method is respectively adopted to solve sub-problems of power flow calculations for the transmission grid and the distribution grid,and integrated distributed power flow calculation of the trans-mission and distribution grid is realized by exchange of the boundary node voltage and equivalent power. Finally,simulation result of the global power system constructed by IEEE-30 node transmission system and IEEE-33 node unbalanced three-phase power distribution system indicates effectiveness of the proposed method.关键词
