Modeling and simulation of a grid-connected photovoltaic converter with reactive power compensation

With the increasing penetration of photovoltaic generation systems in the grid, the use of grid-connected photovoltaic converters for reactive power compensation has been proposed to increase the utilization of the system´s voltage source converter. Power factor correction and voltage regulation at the point of common coupling are among the proposed methods. This paper presents the modeling and simulation of a photovoltaic converter with reactive power compensation connected to the distribution grid. The system is based on a single-stage PV converter controlled using direct power control with space vector modulation (DPC-SVM). Results for day-time and night-time operation are presented.
