This paper proposes a control strategy to smooth the output power of a wind energy system using battery energy storage system (BESS). The proposed control consists of an optimal power extractor, a BESS controller and a grid side controller. The optimal power is obtained using fuzzy controller by setting the duty cycle of the boost converter. Based on the simulation result, the proposed control produces a good performance under high fluctuating wind speeds. The use of fuzzy controller can capture more power than the perturb & observe (P&O) method to wind speeds variation. The proposed control strategy can maintain stable power injection. © 2018 ICIC International.
