Symmetrical Pole Placement Method-Based Unity Proportional Gain Resonant and Gain Scheduled Proportional (PR-P) Controller With Harmonic Compensator for Single Phase Grid-Connected PV Inverters

In this paper, a symmetrical pole placement Method-based Unity Proportional Gain Resonant and Scheduled (PR-P) Controller is presented. The proposed PR-P controller resolved the issues that are tracking repeating control input signal with zero steady-state mitigating of 3rd order harmonic component injected into grid associated use PI for single-phase PV systems. Additionally, has overcome drawbacks frequency detuning in increase magnitude odd number harmonics system constitute common concerns implementation conventional PR developed as an alternative to controller. Moreover, application unprecedented design process based on changing notch filter dynamics around resonant overcomes limitations essentially complexity dependency precisely modelled various controllers such Adaptive, Predictive Hysteresis connected power generation was validated employing Photovoltaic emulator (PVE) consisting DC-DC Buck converter, maximum point (MPPT) algorithm full-bridge inverter designed using MATLAB/Simulink platform. Details controller, simulations, analysis test results were presented paper.
