交直流混合微电网源储协同优化配置
摘要：为提高交直流混合微电网运行效益,需要为分布式电源配置储能系统,以提高微电网对可再生电源的接纳能力。本文以交直流混合微电网为研究对象,提出电源与储能相协同的混合整数优化模型,以确定电源与储能的最优配置。以电源与储能投资成本以及涵盖发电成本与购售电费用的运行成本最小为目标,协同考虑电源与储能的时序动态特性,并计及交直流联络线功率传输损耗。基于Benders分解算法求解混合整数优化模型。算例分析表明,源储协同优化配置方案能够有效提高交直流混合微电网投资运行经济性,验证了本文所提模型的有效性。
Abstract:To improve the operation economic efficiency and acceptance of renewable energy source of the hybrid AC/DC microgrid, it is necessary to configure the battery energy storage system for the distributed generation. In this paper, a mixed integer optimization model is proposed for the hybrid AC/DC microgrid to determine the optimal configuration of generation and storage. In this model, the minimum cost of generation and storage investment as well as the minimum operation cost of power generation and purchase and sale of electricity are taken as the optimized objectives constrained by the dynamic characteristics of generators and storage devices and the power loss through AC/DC converter. The model is solved as a mixed integer optimization based on Benders decomposition algorithm. The case study shows that the optimal configuration of coordinated generation and storage can effectively save the investment cost of AC/DC hybrid microgrid, and verifies the validity of the proposed model.
