Abstract

In order to improve the operation economy and autonomy of rural microgrid, an optimal scheduling strategy of multi-microgrid system is proposed, which considers economy, environmental costs and microgrid autonomy . Firstly, the rural multi-microgrid system structure and distributed power output model composed of three different types of rural microgrids are established, based on which the rural multi-microgrid system optimal scheduling model is constructed. Secondly, improved bald eagle search algorithm （IBES） based on Bernoulli chaotic mapping, Levy flight, nonlinear weight factor and adaptive t-distribution mutation strategy is proposed to enhance the efficiency and accuracy of the optimal scheduling model solution. Finally, MATLAB simulation software is used to build the rural multi-microgrid system model, and the proposed optimal scheduling method of rural multi-microgrid system is verified by comparative analysis. The results show that compared with the traditional bald eagle search algorithm （BES）, IBES improves the system economy and autonomy by 15.75% and 9.51%, respectively. In addition, the optimized scheduling strategy proposed in this study improves the autonomy by about 19.00% compared with the conventional strategy without considering autonomy. Therefore, the proposed optimal scheduling model and the IBES proposed in this paper can rationally distribute rural distributed generation and effectively improve the economic efficiency of the system and the autonomy of microgrid, which is of great significance for the development of new rural power distribution systems.
