摘要：With the liberalization of the market on the selling side, the user’s electricity load shows a stronger volatility, and correspondingly, the price change has a certain degree of dynamics. This paper first selects the working day load of a certain power market to realize the peak-valley period division. Secondly, with the help of Eviews software package, studying the causal relationship between load and electricity price in different time periods, the following conclusions are obtained: the peak time period electricity price has a one-way causal relationship with the peak time period load, and there is a low causal relationship between the electricity price and the electricity load during the flat time period; the valley time period electricity price has a two-way causal relationship with the electricity load.
