Z-source inverter applied to wind power system with battery energy storage system

This paper presents a wind power generation system (WPGS) with battery energy storage system (BESS) based on the Z-source inverter (ZSI) connected to grid. The wind turbines using squirrel cage induction generators (SCIG) are widely accepted due to their robustness, simplicity, light weight and low cost. The SCIG is connected to grid through voltage source converters VSC, and WPGS is reinforced by BESS in order to keep power grid balance. The BESS has a battery bank, which is integrated with the system through a bidirectional DC-DC converter. Moreover, the ZSI is an alternative power conversion topology that can boost the input voltage using passive components. The operation and performance of ZSI is analyzed, the decoupling method real and reactive power is proposed for a double closed-loop control system, which ensures the stability in voltage capacitor of ZSI. Also, the traditional sine pulse width modulation technique is modified to achieve the shoot-through characteristic of ZSI. The proposed system has high performance, minimal component count and increased efficiency. Simulation results verify the efficacy of proposed control strategies.
