Analysis Model of Electricity Purchasing Strategy for Electricity Retailers in Medium to Long Term Electricity Market

Abstract

With the improvement of trading rules in the power market and the exploration of the potential for user side demand response, the role of power retailers in market transactions is becoming increasingly important. The current research on electricity retailers' purchasing plans mainly focuses on the risk avoidance of electricity retailers' multi market combination purchasing, lacking relevant research on the impact of user electricity consumption prediction errors and error adjustment methods on the cost changes of electricity retailers. This article proposes a profit calculation model and an electricity consumption prediction and adjustment model for power retailers. The power retailers are divided into conservative, general, and radical types, and the impact of the adjustment methods of power retailers for user electricity consumption prediction errors on the profits of power retailers is analyzed.
