需求响应下含微电网配电侧市场多目标出清模型

Multi-objective Clearing Model of Distribution Market with Microgrids Considering Demand Response

微电网的高效利用有助于加快电力行业低碳发展。随着电力市场改革的推进,科学合理的市场竞争机制将对微电网的市场化进程产生重要影响。为解决微电网富余电量竞价上网问题,在充分考虑到微电网特性情况下,建立了需求响应下基于分段竞价的多目标竞价出清模型,模型兼顾系统的经济性和低碳性,并提出可移动负荷的优化方法和更合理的混合结算方式。使用非支配排序遗传算法(NSGA-Ⅱ)获得多目标模型的Pareto解集并采用模糊聚类方法进行决策。算例结果表明,采用基于分段竞价的多目标竞价出清模型可以提升微电网的市场竞争力,改善系统的低碳性,对于低碳经济和环境保护将产生积极作用。

The efficient and rational application of the microgrid is conducive to accelerate the low-carbon development of the power industry.With the advancement of electricity market reform,a scientific and rational market competition mechanism will have an important effect on the marketization process of the microgrid.In order to solve the problem of microgrid surplus bidding online,and by fully considering the characteristics of microgrid,a multi-objective bidding clearing model based on block bidding considering demand response is established.The model takes into account the economy and the low-carbon performance of the system.Then an optimized method for translational load and more reasonable hybrid settlement method are proposed.The non-dominated sorting genetic algorithm(NSGA-Ⅱ)is used to obtain the Pareto solution set for the multi-objective model and the fuzzy clustering method is used for decision making.The results of the example showthat the multi-objective bidding clearing model based on the block bidding can improve the market competitiveness of the microgrid and improve the low-carbon performance of the system,and has played a positive role in lowcarbon economy and environmental protection.
