A dynamic photo voltaic emulator using dSPACE controller with high accuracy solar photo voltaic characteristics

An alternative method of testing maximum power point tracking and solar Photo Voltaic (PV) system performance with a solar PV emulator is presented in this paper. Solar PV emulators are Hardware-in-Loop setup, which mimics the characteristics of a PV panel. Further, these emulators are supplementary to strenuous field testing and commercial solar PV training systems available for research prototyping. In this paper, a solar PV emulator built using a DC-DC Buck Converter and dSPACE ds1104 controller is proposed. In addition, MATLAB/SIMULINK Environment is used to construct the Mathematical Model of Solar PV Module. The proposed Solar PV Emulator has the following features: (1) ease in interfacing with faster dynamic response, (2) ability to monitor and control in real-time using a control desk, (3) higher bandwidth DC-DC buck converter, (4) stable output with lower response time, (5) lower output voltage and current ripple, and (6) capability to reproduce near accurate static and dynamic characteristics of...
