中文摘要:

随着大型城市电力供需矛盾的不断加剧，负荷特性调查分析显得尤为重要，这是电网公司做好规划工作的重要前提。本文以郑州电网为例，结合郑州电网历史数据及当前实际情况，对郑州电网2007—2013年负荷特性指标进行统计，并引入灰色关联度理论对影响郑州电网负荷特性变化的因素进行量化分析，找出引起负荷特性变化的主要因素。在灰色关联分析中引入熵权法，克服了传统灰色关联度计算的不足之处，分析结果可为电力系统负荷预测、电网规划建设等提供参考依据。

英文摘要:

With the growing electricity supply and demand in large city, load characteristics investigation and analysis is particularly important, it is an important prerequisites for the power grid companies to do the planning. According to the historical data and the actual situation of Zhengzhou power grid, statistics for the Zhengzhou power network load characteristics index from 2007 to 2013, and then quantitative analyzes the main factors affecting the change of load characteristics of Zhengzhou power grid using the grey correlation theory , finding out the main factors affecting the change of load characteristics. This paper introduce the entropy weight method to the grey correlation analysis, it overcomes the shortcomings of traditional grey correlation calculation, the results can provide reference for the planning and forecasting of power grid, etc.
