With the gradual development of electricity market reform, the peak load ancillary service market has been built in many regions of China. It is necessary to analyse the bidding strategies and earnings of thermal power units in different bidding modes and settlement modes. First of all, according to the cost of thermal power units, the cost of participating in peak ancillary services is studied. Then, based on the accurate prediction of the market clearing price in peak shaving, the bidding strategy and profit of thermal power units under the corresponding market rules are studied. Finally, considering the prediction error of the market clearing price in peak load regulation, the bidding price in peak regulation is taken as a random variable to study the optimal bidding strategy and the maximum expected return of thermal power units. The research results show that thermal power enterprises can improve their own profits by choosing the optimal strategy. Different bidding modes have little effect on the efficiency of market operation, while different settlement modes have obvious effect on the total market peak regulating cost and the peak regulating income of thermal power enterprises.
