Development of real time emulator for control and diagnosis purpose of Photovoltaic Generator

Abstract

this paper proposes a real time emulator for Photovoltaic Generator (PVG), permitting easy experimentation, for control and diagnosis algorithms tests. The DS1104 platform is utilized in order to implement the model developed in Matlab/Simulink software. The APS1102A Programmable DC/AC Power Source is utilized to emulate the current-voltage characteristics of the PVG model implemented in the DS1104 platform. The proposed emulator is tested and validated by considering real conditions variations (namely, temperature and irradiance), and as well as, by injecting some frequently occurring PVG faults. The PVG emulator proposed shows a perfect reproduction of the current-voltage (I–V) characteristics, and can easily handle control and diagnostic algorithms.
