Abstract
The fault ride-through and power smoothing system includes a buck converter for Maximum Power Point Tracking (MPPT) of a PV array power system, a buck-boost converter to connect a supercapacitor energy storage system (SCESS) to the DC link, and a voltage source converter (VSC) to transfer the DC link power to the grid. Three independent controllers are implemented, one for each power electronics block. The effectiveness of the controllers is examined on Real Time Digital Simulator (RTDS).
