Source-load-storage Coordination Partition Optimal Economic Operation of AC/DC Hybrid Microgrid Based on Bilevel Programming Model

  • 摘要: 交直流混合微网作为一种具有前景的微网形式,其优化运行是微网领域内的重要研究课题。该文综合计及交直流混合微网经济性和环保性;并考虑负荷平移构建优化运行模型。将负荷平移策略和储能充放电策略综合考虑为负荷转移手段,以荷储协调负荷转移策略为上层决策变量,并计及负荷平移中用户用电效益损耗以负荷协调转移效益最大估计为上层目标;以交直流混合微网优化运行策略为下层决策变量并考虑交流区和直流区优化运行成本最小为下层目标,建立源荷储协调二层规划模型。应用混沌粒子群算法结合Yalmip优化软件对其进行求解。最后通过算例验证该方法可以提高并协调微网收益和用户效益,并更适用于交直流混合微网实际运行。

     

    Abstract: AC/DC hybrid microgrid is a kind of promising microgrid, the optimal operation of which is an important research topic in the field. This paper established an optimal operation model by taking the economic and environmental protection of AC/DC hybrid microgrid and load translation into account. In this constructed source-Load-storage coordination bilevel programming model, the load translation and energy storage strategy were considered as the load transfer strategy, which was used as the upper level decision variables and the upper level objective function maximizes the transfer benefits concerning user’s benefit loss; The optimized operation strategy was used as the lower level decision variables and the lower objective function minimizes the optimal operating cost of AC area and DC area. To solve the model, chaos particle swarm optimization algorithm combined with Yalmip optimization software was selected. A numerical examples was given to verify that the proposed method can improve and coordinate microgrid’s revenue and users’ benefits, meanwhile is more suitable for the practical operation of AC/DC hybrid microgrid.
