Load flow calculation of integrated shipboard power system based on Particle Swarm Optimization algorithm

Modern shipboard power systems of surface vessels require accurate and efficient load flow solutions to keep its grid voltage static stable. A novel approach to Particle Swarm Optimization (PSO) algorithm for solving load flow calculation problem of integrated shipboard power systems is presented in this paper. The proposed new technique evolves a unique version of PSO by converting forward-backward sweep method into an iterative random searching in continuous solution domain. Case studies on a benchmark test system of a ship´s distribution network demonstrate the introduced methodology succeeds in being the effective one with good convergence on integrated shipboard power system with low X/R ratios.
