摘要
以提高经济性和自供电能力为目标,提出了一种并网型风光储微电网容量优化配置方法,并对其环保减排效益进行了分析。首先确定了适用于并网型微电网的运行控制策略,然后以微源的数量作为优化变量,构建了以年平均综合成本及自供电率为评价指标的数学模型,并采用非支配排序多目标遗传算法对模型进行了求解。最后引入效用理论对各优化结果进行综合评价,以得到不同设计要求下的推荐方案。算例验证了所提方法的正确性和有效性。
In order to improve the economical efficiency and self-supply ability of a grid-connected wind-solar-storagemicrogrid,a optimal capacity configuration method is proposed,and its emission reduction benefit is analyzed. Firstly,an operation and control strategy for the grid-connected microgrid is determined. Then,the number of micro-sources istaken as an optimization variable,and a mathematical model is established with the evaluation indices of annual averagecomprehensive cost and self-supply rate（SSR）. Moreover,non-dominated sorting genetic algorithm with multiple objec-tives is adopted to solve the optimization model. Finally,utility theory is introduced to evaluate the optimization resultscomprehensively,thus recommended schemes are obtained to different design requirements. The validity and effective-ness of the proposed method is verified by a numerical example.
