Abstract:
The relationship between temperature in midsummer and electrical loads in Zhejiang Province is analyzed by means of REOF,regression analysis,correlation analysis,etc.The evaluation model of electricity loads in midsummer is built.The cooling degree days are used as the index to estimate energy consumption for cooling in midsummer.The spatial distribution and the long-term variation features of cooling energy consumption in Zhejiang Province are analyzed.The main results are:(1) There is distinct positive correlation between daily mean temperature and daily mean power load and between daily maximum temperature and daily maximum(power) load.The evaluation equations built on the basis of this theory fit the real electrical loads for cooling well.(2) The cooling energy consumption(cooling degree days) in Zhejiang Province in midsummer fluctuated greatly in the last 50 years.The cooling degree days show a slight downtrend in the northern Zhejiang Province,an obvious downtrend in the southwestern part,and an obvious uptrend in the coastal area.
