Considering allowable deviation and wind speed distribution wind power business day-ahead market strategy bidding

With the development of large-scale wind power integration and electricity markets, wind farms business were asked to participate in the electricity market. Because of the volatility and unpredictability of wind power, the wind farm suppliers contribute to obtain benefits in the bidding at the same time, need to bear the imbalances cost of inaccurately reporting output resulting. This paper follows the objective laws of wind power itself, proposes charging the unbalanced cost that needs to consider the power tolerance when the wind speed of the wind farm satisfies the Weibull distribution, and derives the day-ahead market bidding model in detail for the wind farm business. The model aims to maximize the expected benefits of the wind farm business. The wind farm business in the day-ahead market obtains the revenue from the bidding output, and the unbalanced cost charged by the wind farm business exceeds the allowable deviation of the unbalanced market power. The example detailed analysis of the different wind speed distribution parameters and tolerances ratio on the wind farm business’s effect of day-ahead market bidding output.
