This paper presents a harmonic and reactive current compensator using a voltage source pulse-width modulated inverter. The proposed operation is included as part of the function of battery energy storage system in this study. The control strategy of inverter switching devices is based on the calculation algorithm from the instantaneous power theorem. Its main feature is to maintain the operation system with unit power factor, as well as to suppress the harmonic current generated from nonlinear loads. In this paper, different control methods are applied in simulations. Ramp control can be improved by a fine-tuned compensator, and its performance is proved both in simulation and experiment. In the battery energy storage system, the harmonic and reactive power control mode is also important to the overall operation. The proposed method promotes the battery energy storage system for wider applications.
