This work analyzes the impact of high levels of penetration of the distributed photovoltaic microgeneration on the low voltage electrical grids (127V/220V/380V) 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 electrical grid during imbalances between generation and consumption. In the proposed study, it was made computational simulations with the commercial softwares MATLAB/Simulink® and PSIM®. Experimental results of the proposed control with the equipment of the Laboratory of Otimization of Electrical Systems (LOES), from Federal University of Paraíba.
