Optimal model for deviation penalty of electricity in joint operation of wind power retailer and heat storage electric boiler

Abstract

Because of the randomness and fluctuation characteristics of wind power output, there is a deviation between the bidding output and the actual output of the wind power retailer, and it faces with a lot of penalty fees for deviated power. In order to promote clean heating in the northern heating area, the heat storage electric boiler (this article abbreviates as HSEB) have been gradually promoted. Based on the thermal storage capacity of the HSEB, the deviation of wind power output can be reduced to a certain extent. Considering the comfort range of the indoor human body, the indoor heat supply can fluctuate within a certain range, further increasing the regulation capacity of the HSEB. In this study, taking reducing the cost of deviation penalty as the objective function, and a joint operation model of wind power retailer and HSEB is established. By an example, the feasibility of using HSEB to reduce the cost of deviation penalty is verified.
