提高电力系统能源效率有助于社会经济的可持续绿色发展。首先建立电力系统能源效率评估指标的选取原则,据此在现有常用的评估指标的基础上,从电力系统能源技术效率、能源经济效率、能源环境效率三方面建立基于新能源产业导向的电力系统能源效率评估指标体系。利用Min-max标准化法对指标进行归一化处理,根据专家意见和层次分析法建立电力系统综合能源效率评估模型。以某实际地区电力系统为例,评估分析其系统能源效率,分析影响地区电力系统能源效率的主要因素,以及各因素可带来的系统能源效率提升空间,最后给出提升电力系统能源效率的措施建议。
Increasing the energy efficiency of the power system contributes to the sustainable and green development of the social economy. Firstly, the principle of selecting energy efficiency evaluation indicators for power systems is established. Based on the existing commonly used evaluation indicators, a power system based on new energy industry orientation is established from three aspects: power system energy efficiency, energy economic efficiency, and energy environment efficiency. Energy efficiency evaluation indicator system. The indicators were normalized using the Min-max standardization method, and an integrated energy efficiency assessment model of the power system was established based on expert opinion and the AHP. Taking an actual regional power system as an example, the assessment and analysis of its system energy efficiency, analysis of the main factors influencing the regional energy system energy efficiency, and the various factors can bring about the system energy efficiency improvement, and finally provide measures to improve the energy efficiency of the power system Suggest.
