A Novel Method Mixed Power Flow in Transmission and Distribution Systems by Using Master-Slave Splitting Method

Abstract Traditionally, transmission and distribution power flows are studied and developed separately. In order to face keen competition in the market, the coordinated operation between transmission and distribution systems is required. Therefore, in order to balance the boundary mismatch between the transmission and distribution system models existing in the results of traditional power-flow methods, the transmission and distribution systems are studied as a whole in this article. A novel master–slave splitting iterative method is developed for solving the hybrid mixed power-flow problem. Several case studies are carried out, and the accuracy, convergence, efficiency, and reliability of the proposed method are validated.
