Abstract
To improve the steady-state control effect of photovoltaic grid connected inverters,an automated control method for steady-state error of photovoltaic grid connected inverters considering three-phase voltage imbalance was de-signed.Using a data acquisition system to smooth the operating data of the inverter,constructing a steady-state function for photovoltaic grid connected inverters,determining two control objectives:steady-state error of output voltage and steady-state error of transmission current.By calculating control parameters and predicting the results of the controller,an auto-matic controller for steady-state error of the inverter is designed,and corresponding control algorithms are generated.U tilize control algorithms to adjust control parameters and achieve automated control of inverter steady-state errors.Experimental tests have found that the method designed in this article has high robustness,and the steady-state error value decreases,re-sulting in better control performance.关键词
