This manuscript presents new control strategies for PV and battery integrated Distributed maximumpower point tracking (DMPPT) systems. The presented system shows increased performance underlarge mismatching conditions thanks to the adopted strategies: (i) an adaptive DC-bus voltage extendsthe MPPT operating range of the converters dedicated to control single photovoltaic panels and (ii) theintegration of batteries at module-level further compensates the output voltage level of the converters.A novel output voltage estimation is presented as well, providing full control of the converters' outputvoltages with reduced sensing circuitry. In addition, a sequential control that coordinates PV voltagesand the DC-bus voltage is addressed, as a first step to suitably couple the distributed and the centraltracking of the system. |
