Optimal PMU Placement of the Power Systems Based on Incidence Matrix for Direct Solution of Power Flow

摘要

The character of the power flow equation which can be described by Incidence Matrix is indicated because of the similar character of the Y-matrix and the Incidence Matrix.The method of the optimal PMU placement for the direct solvable power flow is proposed based on incidence matrix. The validity and flexibility of the proposed algorithm are tested with typical standard power system and the results show that the less amount of PMU is needed to realize direct solution of power flow.
