基于经济性与环保性的微电网多目标优化调度研究

Research on Multi-objective Optimal Operation of Microgrid Based on Economic and Environmental Protection

微电网的研究及发展归根结底是为了应对目前能源、资源紧张,环境污染等一系列问题,因此微电网不仅要满足基本供电需求,还应提高其经济性与环保性。文中主要通过建立分布式电源模型及多目标优化模型对微电网内的分布式电源进行优化调度,根据对微电网的具体要求运用遗传算法进行优化计算,进行最优化配置。算例结果通过24 h内不同优化的结果进行对比,得到最优配置,验证了模型在微电网多目标优化方面的有效性,从而达到对微电网整体性最优化。

Ultimately, the research on microgrid is to find the good solution for coping with the series issues from scarcity of both energy and natural resource to sever environmental deterioration nowadays, and so on. The microgrid＇s development is not only to meet the basic demand of power supply, but also to enhance both the economy and the environmental protection. Through the establishment of the environmental protection model and economic model, the optimization of distributed power supply has been achieved by optimized operation for distributed generation of this system, and then by optimizing the computing model using genetic algorithm, which are on the condition of being constrained. The results of example are compared by different optimized results within 24 hours and get the optimization. As a consequence, the optimization of the whole microgrid has been improved accordingly, so as to achieve the whole optimal operation.
