In this paper, the impacts of strategic behavior of wind power plants on electricity markets is studied both in mid and short-terms. To this end, the following schemes forparticipating wind power plants in electricity markets are proposed and compared: 1) wind power plant as a price-takerproducer, and 2) wind power plant as a strategic producer whichgames in supply function. For this study, we need to know the bids of producers. To overcome this problem, it is assumed that themarket has approached to its Nash equilibrium and the proposed schemes are compared at their Nash equilibrium. To consideruncertainty in wind power, different scenarios are considered for wind generation based on its probability density function. Formid-term study, it is assumed that the only available information about realization of wind power is the probability density of windspeed. For short-term study, it is assumed that wind power can beforecasted with a specified probability density function. Finally, to evaluate the strategic behavior of wind power plants, the proposed schemes are compared by applying them to a test system.
