基于改进帝国竞争算法的交直流混合微网经济调度

摘要

随着直流负荷的应用越来越广,交直流混合微网成为备受关注的一种微网形式.针对交直流混合微网运行特性,综合计及经济成本和环境折算成本,考虑功率平衡约束、储能电量约束、可控微源出力约束等约束条件建立了交直流混合微网经济调度模型;对基本帝国竞争算法进行改进,该改进通过交直流混合微网经济调度模型特点引入启发式规则对帝国势力进行重构,建立了计及帝国势力增长速率的殖民竞争过程.采用改进帝国竞争算法对建立的模型进行求解.通过1个算例验证了所提出方法的正确性和有效性,能够保证交直流混合微网经济调度的经济性.%With the more and more extensive application of DC load,AC/DC hybrid microgrid has become a kind of microgrid attracting more attention.According to the operation characteristics of AC/DC hybrid microgrid,the economic dispatch model of AC/DC hybrid microgrid is established considering economic cost,environmental benefits,the constraint of power balance,energy storage capacity constraint,controllable micro source output constraint.The basic imperial competition algorithm is improved by introducing the heuristic rules to reconstruct the imperial forces through the characteristics of the economic dispatch model of AC/DC hybrid microgrid and reconstruction of the colonial competition process considering the growth rate of empire.The improved imperial competitive algorithm is used to solve the model.Finally,a numerical example is given to verify the correctness and effectiveness of the proposed model,which ensure the economic performance of AC / DC hybrid microgrid economic dispatch.
