This project proposes the implementation and development of a control technique for three-phase multifunctional grid-tie inverter, in order to enable the compensation of instantaneous power oscillation. Thus, in addition to injecting active power into the grid, the three-phase inverter will perform compensation functions of currents and voltages disturbing at point of common coupling. The main objective is to carry out theoretical and experimental studies with the purpose of validating, through the conservative terms, power and reactive energy of the Conservative Power Theory, a methodology that allows the identification (decomposition) as well as the compensation of the oscillatory components of the power and reactive energy. Emphasizing that the methodology and control system will be evaluated and tested for an unbalanced nonlinear load operating in conditions where the voltage distortions and unbalances are considerable.
