Comparative Analysis of Different Control strategies in Single phase Standalone Inverter

In this research paper the analysis between different controllers used in standalone Single-phase Photovoltaic (PV) inverters has been presented. Mainly 2 controllers are used such as Proportional Integral controller (PI) and Proportional Resonant (PR) controller. Both PI controller and PR controller can regulate the voltage during load variation. By using PR controller the steady state error of the system can be reduced. The PR controller with standalone PV inverter has better performance by comparing to the PI controller, it has shown by using simulation results. The proposed control methods are significant for the single phase standalone inverter to get the desired output. The reenactment results demonstrate the legitimacy of the proposed PR control conspires. Both simulation and experimental results will be presented. A 3kW isolated PV Inverter was designed and simulated for this research.
