Control of Interfaced Converters with Various Levels of PV Penetration into the Grid: A Case Study

Abstract

The regulation of interfaced converters with the integration of renewable energy sources (RESs) into the power grid with penetration effect is the subject of this article. Various amounts of RES penetration into the grid are used to present a suitable outcome of this investigation. The simulation findings for grid integration with varying levels of PV penetration are presented. A maximum PV penetration of 50% of peak demand is modelled, with a minimum of 10%. This project examines a variety of faults, including symmetrical and unsymmetrical faults. Two controllers are employed in the control process, one for boost converter with maximum power point tracking and the other for VSC controller. The VSC controller regulates the DC voltage. Inner and outer loops exist in the VSC controller. The current is controlled by the inner loop, while the DC voltage is controlled by the outside loop. With these future scenarios in mind, this paper presents existing solutions as well as new and future options to solve these concerns.
