“…The PV interpolation model is a mathematical function that intercepts the short circuit current and the open circuit voltage for producing the I = f(V) characteristic curve of the PV module. Many researchers have considered this model in the PV emulator establishment [14,36,37].…”

“…However, the wrong sizing of external factors and parameters as well as their dependence cause significant oscillations at the emulator output. To overcome this problem, authors in References [14,15] have chosen a fixed step size of the duty cycle for controlling the PV emulator to produce a more stable output. Furthermore, authors in Reference [16] have considered the hybrid-mode controlled method to improve the dynamic performance of the PV emulator affected by the small step size.…”

Applied tests on a real photovoltaic panel for a consolidated analysis require complex experiment setup and permanent availability of climatic conditions. This method is ineffective and can damage the PV system. As a result, PV emulators are highly requested in solar energy conversion and generation research, which rests essentially on a maximum power point tracking control algorithm (MPPT) and an adapting power stage as the DC-DC converter and PV inverter. The PV emulator guarantees a controllable light source environment to act as a real PV system in the laboratory. This paper deals with the study and development of an experimental PV emulator based on logarithmic approximation of the ideal single diode model (ISDM), which is implemented using analog electronic components. Mainly, the PV model, the controller, and the power stages, forming the PV emulator, are described. This simple, low-cost, and efficient device is considered as a nonlinear power supply template replacing the real PV system for any operating point irrespective of the environmental condition changes. The emulated current-voltage and power-voltage curves are validated via resistive load and batteries. Then, the performance of the proposed PV emulator is evaluated by its ability to recharge properly two 12V 7 Ah batteries.

“…Commonly, the calculated PV reference current is used as a reference current for the load current linear regulator, such as proportional-integral (PI) or proportional-integral-derivative (PID) regulator [6], [8], [10], [11]. In [7] and [9] the duty cycle is iteratively updated until the measured load current is equal to the calculated PV reference current.…”

“…Important issue in practical realization of the PV emulator is implementation of the PV mathematical nonlinear model. The PV model could be implemented on various digitals platforms, such as microcontrollers or digital signal processors [5], [7], [8], [11], [13], field programmable gate arrays [9], [14], etc. Especially interesting is using Matlab/Simulink environment for real time implementation of the PV emulators, by utilization of data acquisition boards [12], [15], [16].…”

This paper presents a one solution for photovoltaic (PV) emulator. A main part of the developed PV emulator is buckconverter with recently proposed new I2 dual current mode control (I2 DCMC). The given simulation and experimental resultsdemonstrate excellent performances of the proposed PV emulator: matching between the characteristics obtained from the developedmathematical (simulation) model of the PV module and from the PV emulator, adaptability to the emulated changes in solar insolationand temperature, simple and efficient manipulation with PV module parameters and operating conditions, which is useful especially foreducation purposes, and fast dynamics.

“…Then by using simulation tools like MATLAB or Labview, these data are used as input data for developed hardware [3][4][5]. It is typical for this approach that physical quantities -currents and voltages -are scaled to quantities that are safe for handling and accessible for low cost measurements [6][7][8]. In this way, emulation of different PV modules was done, but there was lack of papers for obtaining emulation of a photovoltaic system in order to predict electricity generation.…”

The paper describes fast emulation of one selected photovoltaic system. This type of emulation reduces emulation time multiple times regarding standard emulation. By speeding up emulation time it is possible to predict electricity generation in advance on a daily basis. This facilitates the evaluation and comparison of electricity generation of photovoltaic systems of different power and/or different photovoltaic (PV) modules. The emulated electrical energy of the selected photovoltaic systems will make it possible to put forward recommendations concerning the choice of the optimal photovoltaic system with regard to the climate elements of the region
