| dc.description.abstract | SOLAR ENERGY CAN BE CAPTURED BY PHOTOVOLTAICS (PV) AND CONVERTED INTO ELECTRICAL POWER. THIS ELECTRICAL POWER CAN THEN BE CONNECTED TO GRIDS BY POWER ELECTRONIC CONVERTERS, WHICH CAN ALSO OPERATE THE PV PANELS AT AROUND THEIR MAXIMUM POWER POINT (MPP), MAXIMIZING THE HARVESTED ENERGY. WHEN THE PV PANELS ARE CONNECTED IN AN ARRAY, THE PARTIAL SHADING EFFECT GENERATES A DISTORTION OF THE POWER CURVE CAN RESULT IN A POWER LOSS SINCE TRACKING ALGORITHMS MIGHT NOT BE ABLE TO DETECT THE MPP. TO SOLVE THIS ISSUE MICROINVERTERS HAVE BEEN PROPOSED, WITH A SMALL POWER ELECTRONIC CONVERTER BEING CONNECTED TO EACH PV PANEL, THIS ARRANGEMENT ENABLES INDEPENDENCE FOR MAXIMUM POWER POINT TRACKING AND ELECTRICAL ISOLATION. THIS PAPER PRESENTS A DOUBLE OUTPUT MULTIPORT MICROINVERTER CAPABLE OF FEEDING DC AND AC LOADS OR PROVIDING CONNECTION TO A SINGLE-PHASE AC GRID AND ENERGY STORAGE. THE PROPOSED STRUCTURE CAN BE OPERATED IN GRID-CONNECTED AND ISLANDED MODES. THIS PAPER DESCRIBES THE MICROINVERTER CONTROLLED WITH THE EXACT LINEARIZATION TECHNIQUE ON BOTH THE DC AND AC SIDES, OBTAINING A LINEAL TRANSFER FUNCTION REPRESENTATION OF THE NONLINEAR AND COUPLED POWER ELECTRONIC CONVERTERS. THE OPERATION OF THE PROPOSED TOPOLOGY AND ITS CONTROL STRATEGY IS VALIDATED USING A LABORATORY PROOF-OF-CONCEPT PROTOTYPE. | |
