Abstract
Togetthe power load characteristics of Shenzhen, this paper analyze comprehensively the relationship between the maximum daily load and temperature in Shenzhen from 2012 to 2014. By introduction of load-maximum temperature gradient and load-minimum temperature gradient, we establish the relation model between the maximum daily load and the maximum daily temperature, minimum daily temperature, and prove its effectiveness by the correlation coefficient.Based this, we obtain the law of the maximum daily load influenced by temperature, which has important significance to improve the accuracy of load forecasting and guide the operation and planning of power grid. Thenby calculation, this paper also get the ratio of Shenzhen annual maximum cooling load, which can reach about 35%. It plays an important part in the summer load of Shenzhen.关键词
