The Impact

The impact of grid-connected photovoltaic power on power quality and reliability of power supply has gained more attention, with the continuous improvement of its generation capacity. This paper describes the power conditioning system of grid-connected photovoltaic power plants based on super-capacitor energy storage, which acts as the energy storage element to stabilize fluctuations in output active power of photovoltaic power generation system. Based on the configuration and principle of the power control system, a power and current double closed loop feedback hysteresis current control strategy is proposed in details, which controls the super capacitor energy storage system to absorb and complement the active power output fluctuations of the photovoltaic power generation system. The effectiveness and good operating performance of the device and control strategy are validated by simulation with PSCAD/ EMTDC.
