Control strategy for isolated wind-solar-diesel micro grid system considering constant load

Abstract

With the technologies of renewable energy maturing, the micro grid will become more competitive. Based on constant load, the paper builds an experiment of the isolated wind-solar-diesel micro grid system. Furthermore, the experiment achieves the goal that it can rationally regulate the diesel generators group, allocate the output power of the renewable energy according to the changes of the weather conditions and the power scheduling strategy. The feasibility and the effectiveness of the proposed approach are proved by the result of an isolated micro-grid experiment.
