基于层次分析和风险熵权的多站融合综合能源系统多指标综合评估

Multi-index comprehensive evaluation of multi-station integrated energy system based on analytic hierarchy process and risk entropy weight

针对多站融合综合能源系统的综合评估,文中充分考虑电网企业特点,提出一种基于层次分析和风险熵权的多指标综合评估方法。文中将社会责任和风险控制作为关键指标,与能源利用率、成本效益、能源耦合效率共同作为子系统指标集,由子系统综合评估得分构成顶层指标集;采用基线网络法对各层指标集进行归一化,采用层次分析法和风险熵权法求解各层指标集的主观、客观权重,进而算得各自综合权重向量;依次加权计算求得子系统综合评分和多站融合综合能源系统综合评估结果。通过算例分析,验证了文中提出的综合评估方法能够客观全面地评价多站融合综合能源系统的运营情况,辅助其进行运营模式和运营策略优化。

For the comprehensive evaluation of multi-station integrated energy system,considering the characteristics of power grid enterprises,a multi-index comprehensive evaluation method based on analytic hierarchy process and risk entropy weight is proposed.In this paper,social responsibility and risk control are taken as key indicators,together with energy utilization rate,cost-effectiveness and energy coupling efficiency as subsystem index set,and the top-level index set is composed of subsystem comprehensive evaluation scores.The baseline network method is used to normalize the index set of each layer,the analytic hierarchy process and risk entropy weight method are used to solve the subjective and objective weights of the index set of each layer,and then,their comprehensive weight vectors are calculated.The comprehensive score of subsystem and the comprehensive evaluation results of multi-station integrated energy system are obtained by weighted calculation in turn.Through the example analysis,it is verified that the comprehensive evaluation method proposed in this paper can objectively and comprehensively evaluate the operation of multi-station integrated energy system,and assist it in the optimization of operation mode and operation strategy.
