基于改进AHP和CRITIC法的配电网规划方案综合评估

Comprehensive evaluation of distribution network planning based on improved AHP and CRITIC methods

针对当前配电网可靠性评估过程中决策因素的不确定性和权重难以量化问题,在配电网网架结构层面提出了一种改进AHP和基于指标相关性的CRITIC指标确定法相结合的智能配电网规划方案评价方法。该方法首先基于配电网网架结构层面建立可靠性评价指标体系,利用改进的层次分析法与CRITIC法计算各评价指标的主客观权重,并采用最小二乘法计算得到综合权重。该方法综合考虑了主客观权重对规划方案的影响,避免了单一观点的局限性,并有效地利用了各指标的数据信息。通过算例分析表明,本文提出的评价方法能有效地评判配电网网架结构层面各决策方案的合理性。

Aiming at the problem of uncertainty and difficult quantititative weight of decision factors in the current reliability assessment process of distribution networks,at the level of distribution network structure,an evaluation method of intelligent distribution network planning scheme combining improved AHP and CRITIC index determination method based on index correlation is proposed.In the research,a reliability evaluation index system is established based on the grid structure of the distribution network,the improved analytic hierarchy process and CRITIC method are used to calculate the subjective and objective weights of each evaluation index,the comprehensive weight is calculated using the least squares method.This method comprehensively considers the impact of subjective and objective weights on the planning scheme,avoids the limitations of a single point of view,and data information of each indicator is effectively used.The simulation analysis shows that the evaluation method proposed in this paper can effectively judge the rationality of various decision-making schemes at the structural level of the distribution network grid.
