Control of DIBBFC for PV and PMSG Based DC-DC Distributed Generation System

A unique converter, a double input buck buck-boost converter (DIBBFC), is considered to develop a DC distributed system with PV as its primary power source. The PV is incorporated in this distributed system at the low input end of DIBBFC. DC source generated using the uncontrolled PMSG is given to the other input terminal of the DIBBFC. Regardless of the changes made to the input or output side of the DIBBFC, the PV always functions at MPPT. After obtaining the peak available power of the PV, the high-voltage DC source, provides the remaining power to meet the requirement at the load end. In this work, three scenarios are presented. These are 1. Change in input torque at PMSG, 2. Change in solar irradiance, and 3. Change in load demand.
