Photovoltaic emulators (PVE) are power electronic systems that are able to reproduce the output “Current-Voltage” characteristics of photovoltaic panels in various operating conditions. They are indispensable for the design and evaluation of the operational components of a photovoltaic energy system, such as battery chargers and Maximum Power Point Tracking (MPPT). Those emulators prevent the experimental testing process on a site and ensure considerable savings in time and cost. In this article, we adopt the rapid prototyping technique incorporating an acquisition board and the toolbox “Real Time Windows Target” of Matlab. For that, we propose to use direct blocs schemes in Simulink in order to simulate and control a hardware target emulating a photovoltaic panel. The experimental platform’s obtained results show that the characteristics of the designed emulator output are in good agreement with those of a real photovoltaic panel, under different conditions of temperature, irradiation and load. © 2014 Praise Worthy Prize S.r.l.

The maximum power point (MPP) of a photovoltaic (PV) system varies with temperature and solar irradiation. The implementation a technical control of the PV power converter systems to search and make this systems to operate at maximum output power is required. The realization of the aforementioned converter and digital implementation of this particular control are presented with experimental results. Hill climbing techniques, which allows tracking the MPP in real time, is implemented. This technique involves in the implementation and comparison of the efficiency of both methods: "Perturb and Observe" (P&O) and the Incremental Conductance (InC). The proposed techniques are validated using the experimental data of 40Wp PV panel (PVP), controlled by a boost converter. Following the comparison of both chosen techniques, output power efficiency and dynamic response are discussed. We also present the advantages and drawbacks of two techniques by using the performed measurements results. © 2015, Praise Worthy Prize S.r.l. - All rights reserved. Source
