Wind, solar and battery micro-grid optimal sizing in Tilos Island

This paper presents a flexible power plant modeling associated with a Multi-Objective Particle Swarm Optimization in order to obtain the optimal size of each plant component. The modeling can be adapted to a wide range of energy sources, storages and loads. The methodology is applied to a Wind Turbine / Photovoltaic array / Battery bank configuration located in Tilos, Greece. The optimization is set up to minimize the system cost and the energy imported from non-renewable sources. The results form a Pareto front representing the trade-off between the equipment cost and the micro-grid autonomy. An optimal solution for a given energy importation cost is detailed as an example
