“…Therefore, in order to evaluate the efficiency of MPPT algorithms, in some application, PV array electronic emulators (PVEE) have been employed [11][12][13]. This happens due to their ability to emulate the non-linear characteristics of PV cells or PV arrays in accordance with distinct climate conditions.…”

“…This happens due to their ability to emulate the non-linear characteristics of PV cells or PV arrays in accordance with distinct climate conditions. The most of the aforementioned electronic emulators have been deployed by means of power electronics converters, based on specifics equivalent mathematic models that represent PV cells [12][13][14][15]. Usually, the photocurrent, diode, and series resistance have been employed to represent most equivalent electrical circuits of PV cells [14,15], while other works also include a shunt resistance to represent the losses of PV current cell leakage [16,17].…”

This study deals with the development of a photovoltaic (PV) electronic emulator (PVEE), operating integrated with a graphic computing platform, for teaching topics related to PV systems in either undergraduate or postgraduate courses. The PVEE is deployed by a DC-DC buck converter to emulate on its output terminals several characteristic curves of a specific PV system, in which climate conditions such as solar irradiation and temperature are taken into account. Emulation of the PV module characteristic curves is embedded in a digital signal controller, which is based on a mathematical model that represents the electric circuit of the PV cell. The educational platform makes possible the following tasks: (i) define and change the PV cell model, (ii) define the number of PV modules, (iii) define and change the solar irradiation and temperature that the PV modules are subjected to, and (iv) visualise voltage and current quantities that are synthesised by the PVEE. From experimental tests, the PVEE is evaluated considering climatic variations involving solar irradiation, temperature, and load transients, whose purpose is to validate the theoretical development. Furthermore, the DC-DC boost converter is employed to perform the maximum power point tracking. Experimental results demonstrate the effectiveness of the proposed system.

Recently direct current (DC) microgrids have drawn more consideration because of the expanding use of direct current (DC) energy sources, energy storages, and loads in power systems. Design and analysis of a standalone solar photovoltaic (PV) system with DC microgrid has been proposed to supply power for both DC and alternating current (AC) loads. The proposed system comprises of a solar PV system with boost DC/DC converter, Incremental conductance (IncCond) maximum power point tracking (MPPT), bi-directional DC/DC converter (BDC), DC-AC inverter and batteries. The proposed bi-directional DC/DC converter (BDC) lessens the component losses and upsurges the efficiency of the complete system after many trials for its components’ selection. Additionally, the IncCond MPPT is replaced by Perturb & Observe (P&O) MPPT, and a particle swarm optimization (PSO) one. The three proposed techniques’ comparison shows the ranking of the best choice in terms of the achieved maximum power and fast—dynamic response. Furthermore, a stability analysis of the DC microgrid system is investigated with a boost converter and a bidirectional DC-DC converter with the Lyapunov function for the system has been proposed. The complete system is designed and executed in a MATLAB/SIMULINK environment and validated utilizing an OPAL real-time simulator.

 Abstract: Maximum value of power can be derived from the solar PV system under the external discomposure and the variable solar irradiance using MPPT technique. Different literatures supplicate a number of MPPT techniques that can capture the power at the particular point known as maximum power point (MPP). This paper focuses on the grey wolf optimization (GWO) based MPPT technique and represents the comparison between PSO MPPT and the proposed GWO MPPT under same solar irradiance. A converter of boost type is implemented in this paper to rise the solar PV voltage. The suggested MPPT technique contributes meticulous and agile expelling for an isolated PV system. Comparisation between the two above mentioned MPPT methods is analyzed by using Matlab/ Simulink environment.Keywords : Grey wolf optimization (GWO), maximum power point (MPP), particle swarm optimization (PSO), photovoltaic (PV) system, maximum power point tracking (MPPT), Simulink.
