基于改进AHP-TOPSIS的储能电站安全综合评估

COMPREHENSIVE SAFETY EVALUATION OF ENERGY STORAGEPOWER STATION BASED ON IMPROVED AHP-TOPSIS

为保障电池储能电站的安全运行,提出一种基于改进层次分析法(AHP)-逼近理想解排序法(TOPSIS)的储能电站安全综合评估方法。首先,综合考虑多方面评估指标,建立储能电站安全综合评估指标体系,对储能电站的安全状态进行全面、客观评估。其次,采用基于指数标度的改进AHP对各评估指标赋权,使得一致性最优,权重系数更精确可靠。然后,通过设计评估参考方案,采用改进TOPSIS实现各储能方案的横向对比及各储能方案与参考方案间的纵向对比,并确定各储能方案的安全等级。最后,以某地4个储能电站安全性能的综合评估为例,验证所提评估指标体系和评估方法的可行性与有效性。

In order to ensure the safety operation of battery energy storage power station,a comprehensive safety evaluation method is proposed based on improved analytic hierarchy process(AHP)-technique for order preference by similarity to an ideal solution(TOPSIS).Firstly,an evaluation index system is established by considering various evaluation indexes,so as to comprehensively and objectively evaluate the safety state of energy storage power station.Then,an improved AHP method based on exponential scale is adopted to determine the weight of each evaluation indicator,which makes the consistency optimal and the weight coefficient more accurate and reliable.Furthermore,through the design of the evaluation reference schemes,an improved TOPSIS is used to realize the horizontal comparison between different energy storage schemes and the vertical comparison between energy storage scheme and the reference schemes,and then the safety level of each energy storage scheme is determined.Finally,taking the comprehensive safety state evaluation of four energy storage power stations as an example,the feasibility and effectiveness of the proposed evaluation index system and evaluation method are verified.
