2022年夏季川渝高温干旱事件对电力供需影响分析
The impact of high temperature and drought events in the Sichuan and Chongqing region during summer 2022 on the power supply and demand
摘要
Abstract
The impact of the frequent occurrence of extreme weather and climate events on the power system is intensified under climate change.In this study,the daily temperature,precipitation and meteorological drought index of the Sichuan and Chongqing region from 1961 to 2022,the daily inflow flow and power generation of Luding,Lizhou and Wawushan hydropower stations from July to September 2022,and the daily electricity consumption and daily peak load data of Chengdu City and Sichuan Province from June to September 2022 were used to analyses the high temperature and drought event in the summer of 2022 and its impact on hydropower generation and power demand.The results show that there was a significant increase in temperature and the number of high temperature days,and an increase in the risk of high temperature and drought in the Sichuan and Chong region from 1961 to 2022.In the peak summer of 2022(July-August),Sichuan and Chongqing experienced the highest temperature since 1961,as well as less precipitation,the largest number of high-temperature days,and the greatest extent of drought.Rainfall and inflow flow are important factors affecting hydropower generation,and the response of hydropower generation to inflow flow is nonlinear.There is a significant positive correlation between summer temperature and electricity consumption,and the daily electricity consumption and peak load exhibit the highest sensitivity to average daily temperature.关键词
