多站融合选址综合评估研究

Comprehensive location evaluation of multi-station integration

多站融合通过融合变电站、光伏电站、充电站等站点功能实现多能源优势互补,但其选址评估中须兼顾多站点影响因素,选址评估权重设计中各单站特性指标权重设计困难,共性指标对各单站影响程度具有差异。为此,文中提出了多站融合选址评估指标体系的构建方法,实现了多个站点指标融合。同时,设计了基于层次分析法的组合权重计算方法,以多站融合指标体系为基础,按单站求出各自所有指标的权重,再设计多站融合的单站的权重,将2种权重结合得到所有指标的组合权重;进一步利用模糊综合评价法对候选站址的各指标进行评分,经过计及权重的综合评价选出最优站址。通过算例验证了所提评估体系和方法的有效性。

Multi-station integration realizes the optimal usage of multiple energy by integrating the functions of substations,photovoltaic power stations,charging stations and other stations,but the location evaluation needs to take into account the influence factors.In the location evaluation weight design,it is difficult to design characteristic indices and common indices for each single station.The common indexes have different degrees of influence on each single site.To solve the problem,a method for the construction of multi-station integration location evaluation index system is designed.Also,the integration of each single station indices is realized.At the same time,the combination weight calculation method based on the analytic hierarchy process and multi-station index system is designed.Firstly,the weights of all indices are calculated for all single stations.Then the weights of the single station are designed.Finally,two weights are combined to get the combination weights of all indices.The fuzzy comprehensive evaluation method is used to score each index of the candidate sites,and the optimal site is selected after a comprehensive evaluation considering the weight.The effectiveness of the proposed evaluation system and method is verified by an example.
