Resumen
Distributed generation allows the Brazilian consumer to generate its own electricity and inject surplus into the grid, these systems in their entirety use inverters to connect to the grid. In order for the connection to the electricity grid to take place in the correct way, a control system is required that acts on the system inverter. This work presents the use of the LQG / LTR controller applied to single phase inverters connected to the electric power grid. In order to perform the LQG / LTR controller study, variations in the network impedance and a disturbance signal at the point of connection to the network are considered. To verify the results, the resonant controller was used for comparison purposes, since it has already been studied for systems connected to the network. Through this study, one can conclude the efficiency of the LQG / LTR controller in the face of uncertainties and disturbances at the point of connection of the single-phase inverter with the electric power grid.
