A review of different methodologies for solving the problem of wind power´s fluctuation

Without wind energy, nothing more than load forecast error is taken into account by system operation and there are already many available methodologies for unit commitment. However, by more wind farm penetration in electrical power production, the reliability of the generation system will decrease, because of the fluctuation and the partial unpredictability of wind power production. As a result, conventional methodologies of unit commitment are not suitable anymore and it is necessary to develop new technologies to solve the problem of wind energy´s fluctuation. This paper proposes a review of different methods for solving the problem of wind power´s fluctuation and forecast errors. It also discusses advantages and disadvantages of each method. At the end, based on analyzing current methods, a discussion for future is proposed.
