Abstract

To realize safe, clean and reliable energy supply in remote regions, integrating clean energy （such as wind, solar, and biogas resources） and constructing integrated energy microgrids （IEM） with renewable energy as the main body is one of the important ways to promote low-carbon, safe and efficient development of power systems in remote regions. Therefore, this paper presents a multi-objective programming method for IEM planning considering the coordinated operation of wind, solar, biogas, and energy storages. Firstly, based on the in-depth analysis of operation and correlation characteristics of various energy conversion equipment in the IEM, the mathematical models for wind, solar, biogas, and energy storage are established. Then, with the minimum system cost and the maximum utilization of renewable energy as the objectives, the multi-objective planning model of IEMs is proposed, while considering constraints for both planning and operation stages. Finally, the NSGA-Ⅱ algorithm is introduced to solve the proposed problem, and the simulation results verify the effectiveness of the proposed model.
