摘要
由于多微网出力的不确定性,且多微网之间的协调运行较差,从而导致其调度成本增加,因此对多微网的经济调度模型进行了改进。以综合发电成本最低、发电排放物对环境污染成本最低和电池损耗成本最低三者作为目标函数,并且考虑微源输出功率约束、功率平衡约束和微网与电网的交互功率,从而对多微网系统进行多目标调度,通过改进的粒子群算法对多微网的最低成本进行寻优。文中对双微网模型进行算例分析,通过仿真发现,该模型能有效降低微网的总体运行成本。
The economic dispatch model of multimicrogrid is improved due to the uncertainty of multi microgrid power output and the poor coordinated operation among multimicrogrids,which leads to the increase of their dispatch cost.The lowest comprehensive power generation cost,the lowest environmental pollution cost of power generation emissions and the lowest battery loss cost are taken as the objective functions,and the micro source output power constraint,power balance constraint and the interactive power between the microgrid and the power grid are taken into account,so that the multi objective dispatch of the multimicrogrid system can be carried out,and the lowest cost of the multimicrogrid can be optimized by the improved particle swarm algorithm.In this paper,the double microgrid model is used for case analysis,and it is found that the model can effectively reduce the overall operating cost of the microgrid through simulation.
