A novel approach based on global positioning system for parallel load flow analysis

A power system is separated into as many subnetworks, referred to as a bordered block diagonal form (BBDF) matrix, as the processors of a parallel computer. Balance loading on all processors is essential to ensure the success of any parallel approach. In this study, a novel method involving the node ordering approach on the basis of calculating the maximum number of fill-in and the degree of every node as the cutest block nodes is proposed. To promote the performance, the synchronized phasor measurement units (PMU_s) installed on the cutest block nodes capture the state variable for solving the load flow equations. Simulation results of the Taiwan Power Company 288-bus system are presented to verify the feasibility of the proposed approach and its capability to implement parallel computing for load flow analysis.
