Resumen
THE CONTROL OF MICROGRIDS AT SECONDARY HIERARCHICAL LEVEL OFFERS MULTIPLE CHALLENGES. WHEN THE ENTIRE MICROGRID IS SEEN AS A MULTIPLE-INPUT-MULTIPLE-OUTPUT (MIMO) SYSTEM AND THE VOLTAGE SOURCE INVERTERS (VSI) CONNECTED AS CONTROL ACTUATORS, DISTRIBUTED CONTROLLERS HAVE BEEN PROPOSED TO INDEPENDENTLY ACHIEVE ACTIVE POWER SHARING, REACTIVE POWER SHARING, FREQUENCY RESTORATION, OR VOLTAGE REGULATION AROUND NOMINAL VALUES. HERE WE ADDRESS THESE ISSUES SIMULTANEOUSLY IN GENERIC SINGLE PHASE MESH-MICRO-GRIDS WITH ARBITRARY NON-LINEAR LOADS, IN ORDER TO DERIVE FORMAL CONDITIONS THAT CAN BE USED TO CHECK IF A GIVEN CONTROLLER ALLOWS TO REACH ALL FOUR MENTIONED CONTROL OBJECTIVES. THE PAPER IS COMPLEMENTED WITH A SIMULATION EXAMPLE WHERE THE MAIN CHARACTERISTICS OF THE PROPOSED METHODOLOGY CAN BE SEEN.
