摘　　要：随着越来越多的分布式电源并入电网,需要考虑分布式电源并网后可能对电网产生的影响,文中从经济性、可靠性和安全性三个方面建立了综合指标评价体系及各个指标的计算方法,然后采用层次分析法(AHP)求取各指标的权重,同时通过效用分析将各指标的计算值模糊化得到其效用值,最后将所有考查指标加权求和得到方案的综合评价值。以福建某地区中压配网为例,建立33节点系统,对不同方案下分布式电源接入方案进行了评估,并对最终评估结果进行了分析,验证了方法和体系的合理性、可行性。More and more distributed generations are integrated into distribution network,which brings some chal- lenges to the grid. This paper introduces a comprehensive method to evaluate the impacts of grid-connected dis- tributed generation in three aspects as economy,reliability and security. The calculation method corresponding to each index in different aspects is also given. Analytic hierarchy process （AHP）is adopted to build the hierarchy of index and set the weight to each of them. Then,the comprehensive evaluation is achieved by setting the index weights and using the fuzzy algorithm,which converts the calculation results of each index into dimensionless quan- tity. The method is illustrated by a case study of a 10 kV distribution network in Fujian Province. Different grid- connected distributed generation conditions are evaluated, which verified the rationality and feasibility of the method.
