In a competitive bid-based markets, power generation groups desire to improve bidding strategies that maximize their profits. This paper provides the optimal bidding strategy model of the agent which is a price-maker hydro-electric producer in day-ahead electricity market. In a market with both price makers and price takers, price makers will most likely bid above their marginal costs. The main concern of the problem is that the market-cleaning price depends on how much the price maker bids, and the quantity the price maker produces depends on the market-cleaning price. The most difficult of the problem is for hydro producers as price maker, where the problem is non-convex, inflows are uncertain, and hydraulic coupling in the same generation group. A price-based cascade reservoirs schedule has to consider market price uncertainty and the information revealing nature of electricity markets. For this environment stochastic programming models are suggested to derive the optimal cascade reservoirs policy. In order to overcome the difficulty of solving double uncertainty optimization problem, using the fuzzy clustering neural network model to predict the future inflow. Then it will obtain the cascade reservoir schedules by considering the different price risk conditions, and the best bid price and the bid quantity by optimizing the dispatching. The proposed method is applied by the dispatching center of Guizhou’s electricity market, which a hydroelectric generating group makes up 80% of all electricity generation.
