Optimal Hybrid Energy Solution for Island Micro-Grid

Electrification in remote islands is an urgent project to improve social life in the developing countries. With site survey, the electric power supply improvement in Batanes, Philippines, is selected as an example for optimal sizing practice for renewable power system study. A DC link system configuration is recommended to include diesel generators, photovoltaic panel, wind generator and battery bank as a hybrid energy solution to adopt. From real system and environment data, the generic algorithm is adopted to work with HOMER analytical software to figure out optimal installation capacity for system operation. In this paper, the proposed genetic algorithm adopts slightly different model as HOMER and find some significant optimal results with better solution efficiency. It comes out with an optimal hybrid energy system of PV/WT/Bat/DG in different strategies.
