Optimal allocation and sizing of capacitor banks for maximum power transfer to selected areas

摘要

Voltage stability has become a very important issue of power systems analysis. Therefore, the main contribution of this paper is to develop computer algorithm using hybrid variant of mean-variance mapping optimization (MVMO-SH) algorithm to find optimal allocation and the appropriate size of capacitors, which are required for maximum power transfer to selected area in the network. The fitness evaluation in MVMO-SH algorithm is found by Newton Raphson Power flow (NRPF) to determine important voltage stability index called voltage stability margin index (P). The method of finding out voltage stability margin index is also proposed. The concept, mechanism and implementation of MVMO-SH are discussed in this paper. The obtained results indicate the effectiveness of the approach applied in this paper to find the best location and appropriate size of multiple shunt compensators to the desired targets which is maximum power transfer to the selected area.
