This research project proposes the discussion and study of an energy management system (EMS) for low voltage microgrids, aiming to optimize generation and consumption of energy in local and/or distributed level. The microgrid may be composed by several generation units, e. g., PV-generators and/or wind-power generators, and those technologies have a switched power interface (SPI), which is responsible for the control of power flow between the microgird and the main grid and also may be regulated to improve voltage stability, ensure the power quality (PQ) and elevate the efficiency of the microgrid. The approach is based on Conservative Power Theory. The main goal is to evaluate the applicability of control techniques based on conservative terms (power and energy) and/or orthogonal current components calculated using system measurements to manage generation and/or power conditioning in the microgrid. Thus, the EMS will be an intelligent platform that will integrate various local and/or cooperative control algorithms running in each component of the microgrid, allowing the smart operation of the energy suppliers and the maintenance of power quality indexes in the microgrid.
