基于改进AHP的配电网规划评价体系研究
|
摘要
如何在多个配电网规划方案中选择出最优方案,对于电力系统合理规划及保障电力系统安全运行有重要意义。提出了考虑微电网接入的配电网规划评价指标体系,采用改进的层次分析法(AHP)方法对配电网规划方案进行指标权重计算,并采用考虑指标权重的加权求和法求取方案最终评分。改进的AHP方法包括采集多个专家意见并根据各个专家经验的不同构造加权平均判断矩阵;对一致性检验方法进行改进以提高计算结果的一致性。最后通过算例分析,采用所提出的评价方法,对4种规划方案进行了综合评分,评分结果为方案1得0.285分,方案2得0.196分,方案3得0.307分,方案4得0.212分,该评价结果与专家评估结果相一致,验证了该方法在配电网规划评价上的科学性和合理性。
It is of great significance to the reasonable power system planning and guarantee the safe operation of the power system that determine the distribution network planning.This paper puts forward the evaluation index system of power distribution network planning considering micro grid access.Distribution network planning scheme for the calculation of index weight through the improved AHP method,and the final plan evaluation using the weighted sum method.Collecting multiple expert opinion and according to the different structure of the expert experience weighted average of the judgment matrix and improving the consistency check method is the AHP improved thoughts.Finally,through the case analysis,using the proposed evaluation method and comprehensive score of 4 kinds of planning.Grading result is the plan 1,2,3,4 respectively scored 0.285,0.196,0.307,0.212.The evaluation result and expert evaluation result are consistent,and this method was verified in the scientific nature and rationality of evaluation on power distribution network planning.
