Abstract


The design and control of power converters required for DC-DC and DC-AC conversions are critical to enhancing durability, reliability, and efficiency. The interfacing power converters are essential for power conditioning for efficient load management. In part 1 of this work, a grid supporting control, which makes the photovoltaic-based microgrid operate as a current source and at the same time contribute to the frequency and voltage regulation, is proposed and analysed under a changing load and photovoltaic source's intermittencies. The grid sup-porting scheme proposed implements droop alongside an MPPT, which dynamically modifies their operating parameter according to the microgrid and the host conditions. The performance of this control is evaluated based on its ability to improve the voltage and frequency control. Consequently, the design and control of power converters required for DC-DC and DC-AC conversions are critical to enhancing durability, reliability, and efficiency. The grid-supporting system developed is suitable for the double stage photovoltaic system operation. Thus, an adaptive grid supporting control using a droop control that integrates an MPPT for a DC-DC boost converter is added to an inverter based microgrid in grid supporting mode.  Thus, a primary control scheme for the interfacing grid inverter used with a DCDC converter is modelled in this work.
