摘要
Due to the uncertainty in consumers’ forecasted demand, it is inevitable that there exist deviations between retailers’ bidding demand in the day-ahead wholesale market and their actual demand, which will be penalized by the market operator. In order to investigate the impacts of the deviation penalty mechanism on retailers’ bidding strategies, a game-theoretic model of the day-ahead wholesale market considering retailers’ bid deviation penalty mechanism is proposed. In this model, it is considered that retailers strategically bid their load demand and generators strategically offer their supply functions. In addition, retailers have to pay penalties for their over-bidding and under-bidding deviations with different penalty prices. A scenario reduction technique is employed to describe the uncertainties of retailers’ actual demand. This model is solved using the nonlinear complementarity method. Numerical examples show that the deviation penalty mechanism can effectively induce retailers to reduce their bid deviations. This study will help the market operator to mitigate the retailers’ bid deviations by means of  appropriate penalty prices.
