Abstract

A novel approach involving the network diakoptics technique is proposed in this study to evaluate in parallel the penalty factor term. The transposed Jacobian matrix derived from the load flow equations can be separated into as many independent subnetworks, referred to as a bordered block diagonal (RED) matrix, as the processors of a parallel computer. However, effectively solving the cutset block of a BBD matrix in parallel is a relatively difficult task. To alleviate this limitation, the voltage controlled buses should be selected in any cluster, hence, the penalty factors associated with the cutset block are ones and the computation time is reduced. Simulation results of the IEEE test systems and the Taiwan Power System confirm the feasibility of the proposed approach and its capability for implementation parallel processing for the economic dispatch analysis.
