微电网多目标优化运行研究

Research on Multi-objective Optimal Operation of Microgrid

微网是解决国家电力系统问题的重要辅助手段之一。为协调微源、储能单元、电网、和负荷之间的能量平衡和流动,同时实现微网运行的经济调度、环境保护、可靠供电等要求,需要提出可行的能量管理策略。首先从经济、环境、电能质量、供电可靠性等方面提出目标函数,然后列出约束条件,最后介绍优化算法并进行分析比较。

Microgrid is one of the supplementary means to tackle the problems in national grid.To coordinate the flow and stability between distributed generators,storage batteries,grid and load while insure economic dispatching,environmental protecting and power supply reliability,it is necessary to do research on energy management of microgrid.First,the optimization models are presented concerning economy,environment,electricity quality and supply reliability.Then constraints are introduced.At last,optimization algorithms are presented,and comparison and analysis are also made.
