Abstract:With the changes of the energy structure and load demand characteristics of Guizhou Power Grid, the peak-to-valley difference of the power system has gradually increased, and the peaking problem has become increasingly prominent. In order to explore the peaking response potential of high energy load, and study the feasibility of high energy consumption industry to participate in peaking auxiliary service, the energy structure and peaking status in Guizhou are analyzed, the characteristics of electricity consumption of typical high energy-consuming industries such as electrolytic aluminum, cement and steel and the feasibility of participating in power grid peaking are summarized. Finally, based on the implementation status of power system reform and auxiliary service market, a trading mode of peaking auxiliary market is proposed in this paper, which is suitable for high energy-consuming industries. The implementation of the trading system can achieve a win-win situation between the power generation side and the load side, which helps to improve the enthusiasm of the load side resources to participate in peaking, and has certain guiding significance for the construction of the peaking rights trading market.
