荷-网-源协调控制后电网降损能效评估指标体系

摘要

Grid loss reduction has an important impact on the economic operation of power system. In terms of the supply side, grid side and load side, this paper comprehensively considers the factors, which have an effect on the grid loss reduction. Then the evaluation index system of grid loss reduction is established, and the detailed explanations of the meaning and calculation of the indexes are presented. Through the analysis of grid loss reduction potential in Gansu province, this paper uses analytic hierarchy pro⁃cess to calculate the weight of each index in the assessment index system, which provides solutions for the comprehensive evaluation of grid loss reduction and energy efficiency after load⁃ network⁃source coordinated control.%电网损耗的降低对于电力系统的经济运行具有重要的意义。分别从负荷侧、电网侧和电源侧3方面综合考虑电网降损的影响因子，建立了电网降损能效的评估指标体系，阐述了体系中各指标的意义，给出了各指标的量值计算方法。通过分析甘肃地区的电网降损潜力，采用层次分析法计算出评估指标体系中各指标的权重，为荷—网—源协调控制后电网降损能效的综合评估提供了解决方案。
