Reactive Power Control of Distributed Photovoltaic Generation System in Low Voltage Electrical Grids

This work analyzes the impact of high levels of penetration of the distributed photovoltaic generation on the low voltage electrical grids (127V /220V /380V) of the electric power distribution system. It also presents a proposal of control based on αβ-dq coordinates for distributed generation with solar panels, which aims to inject reactive power to adjust the voltage at the connection point of the generation system with the electric grid during imbalances between generation and consumption. The simulations were performed using the Matlab/Simulink® software.
