In order to maximize the ability to improve the tracking wind power schedule output, based on the ultra-short term forecasting of wind power, a charge and discharge power control method of energy storage system containing five control coefficients is proposed, and using the particle swarm optimization algorithm, a method to optimize the charge and discharge control coefficients for real time is put forward to reduce wind power short-term prediction error. Finally, taking the typical wind farm output for example, simulation verifications have been performed, the fixed coefficients and moving optimization coefficients methods were compared, and the factor affecting the accuracy of prediction is analyzed, the results show that the proposed control method is effective.
