Power Generation Curve Clearing Algorithm based on High-Low Match Auction Mechanism

Abstract

In the era of power production with coal and gas as the main fuel, the output value of the power system is easy to control and adjust. Therefore, the traditional power trading only focuses on the research of transaction method of electricity quantity. After the addition of clean energy, the output value of power system fluctuates greatly and is difficult to control. At this time, the trading mechanism which only takes electricity as the main factor is no longer applicable. It is necessary to consider adding the fluctuation factors of electricity into the trading process, and use the power of the market to change the purchase decision and electricity consumption habits of users, so that the fluctuation of electricity use curve is consistent with that of power generation curve. Based on the high-low match auction mechanism, this paper designs a clearing rule considering the fluctuation of generation curve, and gives an example to verify it.
