Abstract:

提出含风力、光伏等分布式电源和微电网之间的混合集成供电系统及其优化配置方法。与分布式电源直接并网以及微电网集中供电方案相比,该混合供电系统具有明显的技术经济性,并且能够根据运行过程中遇到的故障及检修等情况,转换供电模式,供电模式灵活,可靠性高。在混合供电系统中,为了合理配置分布式电源、负荷以及储能,建立以投资成本、电网电量不足期望以及网损为目标函数的多目标优化模型。采用基于精英策略的非支配性排序遗传算法(nondominatedsortinggeneticalgorithmII,NSGA-II)求解出混合集成供电系统中分布式电源、负荷和储能的优化配置方法。通过IEEE33节点算例和某实际电网建设项目的测试表明所提出的模型和算法合理、可行。
