Abstract
<span lang="EN-GB">Distributed control strategyrepresents the most promising solution to enhance the lackluster energetic performance of mismatched PhotoVoltaic (PV) systems. Moreover, many factors that contribute to such poor performance are still to be explored. To fully understand the advantages offered by the Distributed Maximum Power Point Tracking (DMPPT) approach, the implementation of a DMPPT emulator is necessary. Based on the above needs, this paper describes the realization and use of a Buck based DMPPT emulator and shows its high flexibility and potential. The realized device is capable to emulate the output current vs. voltage (I-V) characteristics of many commercial PV modules with a dedicated Buck DC/DC converter not only in controlled atmospheric conditions but also with different currents rating of the switching devices. The system implementation is based on a commercial power supply controlled by a low-cost Arduino board. Data acquisition is performed through a low-cost current and voltage sensor by using a multichannel board by National Instruments. Experimental results confirm the validity and potential of the proposed DMPPT emulator.</span>

Summary
The world is currently in a dramatic climate crisis due to the growth of greenhouse gas emissions. Various Maximum Power Point Tracking (MPPT) control techniques have been proposed in the literature to track the MPP and force the system to work at the MPP point, including high-performance MPPT techniques [9]-[19], reconfiguration architectures and algorithms, [20]-[29] and Distributed MPPT (DMPPT) approach [30]-[41]. Among of all these techniques, the DMPPT (Figure 2) is by far the most promising solution to enhance the reduced energetic performance of mismatched PV systems [30]-[41]. The present paper is organized as follows: the mathematical model of a single Buck based DMPPT unit is described in detail in Section 2; Section 3 highlights the still open issues regarding the DMPPT approach; Section 4 is dedicated to the design and description of the proposed Buck based DMPPT emulator; experiments and tests are presented in Sections 5; Section 6 draws the conclusions
