多能互补城市能源系统的低碳能效评估方法OACSTPCDEI
Carbon efficiency evaluation method for urban energy system with multiple energy complementary
城市能源系统在清洁能源的消纳和能源梯级利用方面发挥着重要作用,低碳能效综合评估则对多能互补城市能源系统的建设和运行有着重要意义.首先,本文构建了包含能源利用;环境保护;系统运行;经济效益4个一级指标和21个二级指标的多维度评价体系,可对城市能源系统的特征进行全面刻画.其次,考虑到评价体系包含大量指标,导致各指标间存在信息重叠,提出了一种基于数据处理;降维;组合权重和灰色关联分析的能效评估方法,该方法可有效减少计算量,提高能效评估的准确性.再者,以…查看全部>>
Urban energy systems(UESs)play a pivotal role in the consumption of clean energy and the promotion of energy cascade utilization.In the context of the construction and operation strategy of UESs with multiple complementary energy resources,a comprehensive assessment of the energy efficiency is of paramount importance.First,a multi-dimensional evaluation system with four primary indexes of energy utilization,environmental protection,system operation,and econo…查看全部>>
