孤岛模式下风光储微网容量优化配置策略研究

Confi guration Optimization of Capacity of Island-mode PV-Wind-Battery Hybrid Microgrid

为了保证供电可靠性并提高整个微网系统的经济性,本文基于典型风光储微网系统模型,以满足基本用电负荷为前提,进行微网系统最优容量配置。根据风电、光伏、蓄电池的自身运行特性及其成本,本文提出以系统投资成本、运行成本和维持系统供电可靠性等综合成本最小为目标的优化配置策略;利用遗传算法来获得系统的全局最优解;最后,利用HOMER软件对所得结果进行检验。仿真结果最终验证了模型和算法的合理性。

To improve the economy of whole microgird while the power supply reliability is ensured, this paper decided to make an optimal design of capacity configuration ,this study is base on the universal microgrid system and it must supply the basic power demand, we propo-sed an optimal configuration strategy ,which is aimed to make the capitalized cost and the ope-rating cost and other productljion cost reaching an minimum value . We used the GA（Genetic Algorithm） to get the system globally optimal solution and inspect the result through the Homer software.the reasonableness of the proposed models is verified by case study results.
