含风光储的城市微电网优化配置

Optimal Configuration of Urban Microgrid with Wind/Photovaltaic/Energy Storage System

多种能源互补的微电网供电模式是解决未来能源问题的有效途径之一。根据风、光等分布式发电的特点,结合储能系统的特点,提出了独立微电网的典型结构和系统运行策略。在此基础上,提出了含风/光/储的微电网电源容量优化配置模型,建立了含设备成本等年值与年运行费用以及可再生能源利用率的目标函数,采用多目标非支配排序遗传算法进行求解。以某地区独立微电网为例,验证了所提优化方法的有效性,为独立海岛微电网的优化配置提供了理论依据和技术支撑。

Multi-energy hybrid microgrid power supply mode is one of the effective ways to solve the future energy problems. According to the characteristics of distributed generation such as wind, solar and so on, the typical structure and operating strategy of the separated microgrid were proposed. Based on this, the optimal configuration model of mi- crogrid power generation with wind/photovohaic/energy storage was put forward, and the objective function of annual operating expenses and renewable energy utilization was established. The multi-objective non-dominated sorting ge- netic algorithm was used to solve the problem. The effectiveness of the proposed optimization method was verified by the example of a certain area microgrid,which provided a theoretical basis and technical support for the optimization of the island microgrid.
