Abstract
As a renewable resource, photovoltaic power generation has become more and more attracted and applica-ble.According to Test Procedures for Photovoltaic Power Station Connected to Power Grid, this paper develops a grid disturbances device with functions of energy feedback applied to photovoltaic grid-connected detection, to simulate the disturbances of the frequency, amplitude of the voltage of power networks.The device has a back-to-back double PWM topological structure, including two-level PWM rectifier and three-level PWM inverter.The rectifier uses the voltage and current dual-loop control, and the inverter uses the voltage single-loop control.The control strategies can accurately track the reference, respond quickly and the steady-state error is small.The simulation and experiment re-sults show that the circuit design and control strategy are feasible and efficient.关键词
