Abstract:In order to solve the power supply problem in remote areas, isolated microgrid scheme with multi-energy complementary was proposed, and optimal disposition result was obtained. In terms of the isolated microgrid scheme, based on the consideration of economic, environment, reliability, economic disposition model was built, and simulated by HOMER with load following control strategy to optimize output of distributed energy, thus getting the optimal result. The effectiveness of the proposed method was verified by calculation results of a test system and influence on result was analyzed when parameters changed. Furthermore, compared with the scheme based on the proposed critical economic distance, the method in this paper was demonstrated reasonably.
