Performance Enhancement of PV Systems Using Adaptive Reference PI Controller

Abstract

The Solar photovoltaic (PV) energy has many advantages which makes it one of the great sources for power generation. Photovoltaic systems are linked to the electrical grid with the help of a DC-AC converter and a DC-AC inverter. The project's major goal is to improve the grid's interoperability with PV installations. To get the desired performance, the converter as well as inverter characteristics are adjusted. The inverter is controlled by an ARPI (adaptive reference PI) controller, which improves the performance of the system by allowing for low voltage ride through (LVRT). It also smooths out the oscillations in PV-generated electricity that occur because of the due to environmental changes. The converter is utilized to provide MPPT while the PV system is under varied environmental conditions (MPPT). To assess the efficiency of the suggested method, a simulation of system performance employing the suggested ARPI is provided.
