基于混合整数规划的微电网日前优化调度模型

Day Ahead Optimal Dispatching Model of Microgrid Based onMixed Integer Programming

为了提升微电网的效益,妥善管理微电网内的分布式电源和储能的运行,实现微电网经济、技术效益的最大化成为了研究热点。文章以微电网内负荷平均供电单价最小为目标,考虑风、光、蓄电池组成的微电网与主网之间的能量交换,建立了一个混合整数规划模型,最后通过实例对模型进行了仿真,仿真结果表明考虑可再生能源的参与可以提高微电网的经济性,验证了所提模型的有效性。

In order to improve the effi ciency of microgrid,properly manage the operation of distributed power and energy storage in microgrid,and realize the maximization of economic,technological benefi ts of microgrid has become a research hotspot.In this paper,a mixed integer programming model is established to minimize the average unit price of power supply in the microgrid,considering the energy exchange between the microgrid and the main grid composed of wind,light and battery.Finally,an example is given to simulate the model.The simulation results show that considering the participation of renewable energy can improve the economy of microgrid and verify the effectiveness of the proposed model.
