Real-time Implementation of Robust Controller for PV Emulator Supplied Shunt Active Power Filter

The aim of this paper is an implementation of shunt active power filter (SAPF) supplied by PV generator dedicated to power quality improvement, power factor correction and smooth PV energy injection. SAPF is full bridge inverter controlled by direct current control (DCC) algorithm which consists of an outer voltage regulation loop integrating a fractional order integral plus proportional controller (FO-IP) and an inner current control loop. The PV generator is composed of an emulator with multilevel irradiations, boost converter and P&O algorithm to ensure maximum power tracking. The validity of the global control system has been performed using real-time bench built around a real-time dSPACE card. The results obtained confirm the high performance in steady and transient states of the proposed controller.
