摘　　要：为解决光伏高渗透低压台区的电压越限、三相不平衡等问题,引入含储能柔性互联装置(FID),实现台区间的功率互济与优化运行。针对低压多台区柔性互联的运行评价方法,提出一种基于AHP-CRITIC组合赋权的改进TOPSIS评价模型。首先,从含储能FID接入对台区改善较为明显的运行电压、运行功率、运行经济3个方面建立评价体系;其次,通过AHP法与CRITIC法确定主、客观权重,利用纳什均衡理论实现AHP-CRITIC组合赋权;然后,基于加权灰色关联度改进TOPSIS,进一步反映指标内部变化。最后,以实际台区为算例,分析所提方法的有效性。To address the issues of voltage over-limit and three-phase imbalance in low-voltage distribution areas with high photovoltaic penetration,an energy storage-inclusive Fault Indication Device(FID)is introduced to facilitate power mutual aid and optimize the operation of the distribution areas.In response to the operational assessment challenges of flexible interconnection in multiple low-voltage distribution areas,an improved TOPSIS evaluation model based on AHP-CRITIC combination weighting is proposed.Firstly,an evaluation system is established from three aspects:improvement in operating voltage,operating power,and operating economy,with the introduction of energy storage-inclusive FID.Secondly,the main and objective weights are determined using the AHP and CRITIC methods,and Nash equilibrium theory is employed for AHP-CRITIC combination weighting.Subsequently,the TOPSIS method is enhanced based on weighted grey relational degree to further reflect the internal changes of indicators.Finally,the effectiveness of the proposed method is analyzed using an actual distribution area as a case study.
