Jeudi 28 mars à 10h - Séminaire de Oswaldo López Santos (séminaire commun avec l'Axe Energie et le LIA MIRC) :

" Improved control of the boost inverter feeding AC loads as a part of a hybrid microgrid "
Hybrid AC/DC microgrids have several advantages such as flexibility, scalability, reliability and high efficiency, among others. Power conversion in these structures is accomplished by means of multiple converters providing unidirectional and bidirectional DC-DC and DC-AC power flow. To feed AC loads, it is possible to use the grid voltage for sharing demanded power or to use a stand-alone inverter producing the required AC voltage from energy produced and stored into the microgrid. This last case allows not only operation of the microgrid in islanding mode but also providing voltage for loads in grid connected mode when the quality of the grid is poor. As one of existing alternatives to do this unidirectional power processing task, the boost inverter provides a structure composed by two boost modules which is flexible in terms of power but has some additional complexity in terms of control when compared with traditional full bridge. Integrated in the context of hybrid microgrids for rural zones in developing countries, this seminar presents a sliding mode control approach for the boost inverter which shows improved performance because the voltage gains required for each module during one fundamental cycle is considerably reduced.
