Sizing a self-sustaining wind-Diesel power supply by Particle Swarm Optimization

Hybrid wind-Diesel systems can be an attractive solution for the supply of remotely located consumers or the provision of enhanced energy independence in the Near-East region, especially in Gaza strip. Such stand-alone system contains a wind turbine, batteries as short term storage as well as hydrogen storage tanks as long term storage devices. The proposed system leads to a remarkable reduction in the fuel consumption, in comparison with Diesel only systems. For proper sizing of the particular system components under minimization of the Life Cycle Cost (LCC), the metaheuristic computational method of Particle Swarm Optimization (PSO) was successfully applied; this is exemplarily shown by the electricity supply of a hospital in Gaza strip where the energy requirements are fully met under regard of specific constraints and restrictions.
