Optimization of a Microgrid Integrated with Renewable Energies using PSO

Nowadays, microgrids (MGs) play a crucial role in modern power systems due to possibility of integrating renewable energies into the MG system. It is expected in near future collaborating microgrids as a community has a great affect in providing efficient energy for suppliers. Therefore, optimal operation of a MG, as a first step, is an important issue in this field. In this paper, by considering an integrated MG comprised of conventional generators, photovoltaic and wind a particle swarm optimization (PSO) is applied to minimize the cost function of the MG. Finally, the simulation results are discussed and analyzed to evaluate the system operation.
