层次分析法在孤岛微网综合评价中的应用

摘要

In the microgird network,the option of control strategy would impact the whole system running.It is necessary to study the different control strategies in the comprehensive evaluation of microgird.In this paper,the comprehensive evaluation index of microgird is analyzed.The index weight of factors and the comprehensive evaluation system with the analytic hierarchy process (AHP) and Delphi method are established to evaluate the microgird under different control strategies.For example,in one island micro network,the operation is evaluated with three control strategies including load follow,charge cycle and scenery wood.The result shows that the operation of micro network performs best with the charge cycle strategy.%孤岛微网系统中的控制策略,能够对系统的整体运行产生很大影响.在对孤岛微网进行综合评价时,对不同的控制策略进行研究是非常有必要的.采用层次分析法和德尔菲法对孤岛微网的综合评价指标进行分析,确定各指标的权重,构建孤岛微网综合评价体系,对不同控制策略下的孤岛微网进行综合评价.以某孤岛微网系统为例,对循环充电、风光柴、风光储3种控制策略下的微网系统进行综合评价.结果表明,在循环充电控制策略下,孤岛微网的运行最优.
