This thesis presents an intelligent controller based on the recurrent fuzzy neural network (RFNN) algorithm for the battery energy storage system (BESS) using in the wind farm power smoothing application. A two-stage BESS is composed of a bidirectional DC/DC converter and a three-level inverter. The purpose of wind farm power smoothing control is to mitigate the wind farm power fluctuation problem when it is fed directly to the grid. The proposed wind farm power smoothing control method can maintain the quality and stability of the power system and reduce the required BESS capacity and the investment cost. Moreover, the network structure and on-line learning algorithm of the RFNN are introduced in detail. Additionally, some simulation results are given to verify the design of the BESS via PSIM. Finally, the feasibility of the proposed control scheme is verified using some experiment results.
