Abstract—This paper proposes Particle Swarm optimization algorithm based on Membrane Computing (PSOMC) for solving optimal reactive power dispatch problem. PSOMC is designed with the framework and rules of a cell-like P systems, and particle swarm optimization with the neighbourhood search. In order to evaluate the efficiency of the proposed algorithm, it has been tested on IEEE 30 bus system and compared to other specified algorithms. Simulation results show that PSOMC is superior to other algorithms in reducing the real power loss and improving the voltage stability.

Index Terms—membrane computing, particle swarm optimization, optimal reactive power, transmission loss.
