A Multi Objective Approach for Optimal Design of Solar/ Wind/ Biomass/ Battery-Based Grid Connected Microgrid System

Due to the depletion of fossil fuels the dependency on the reliable and ecofriendly alternative sources has increased. The renewable energy sources have become alternative sources for the fossil fuels. However, there are some issues with the renewables which include uncertainty, reliability, high cost and intermittency of the sources. By integrating the multiple renewable sources together these issues can be minimized. In this study grid integrated wind, solar, biomass and battery based microgrid system is proposed using a multi objective artificial cooperative search algorithm (MOACS) with the objective to minimize the annual life cycle costing (ALCC) with high reliability (minimizing the loss of power supply probability (LPSP)). Different case studies have been presented and the comparative study proves the supremacy of the proposed approach.
