The Relationship Between Load and Electricity Price in Different Time Periods Based on Granger Causality Test

Abstract

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.
