This paper provides a review on various PV simulator technologies as well as presents a novel equivalent photovoltaic (PV) source that was constructed by using un-illuminated solar panels and a DC power supply that operates in current source mode. The constructed PV source was used for testing photovoltaic converters and various maximum power point tracking (MPPT) algorithms required for capturing the maximum possible output power. The mathematical model and electrical characteristics of the constructed PV source were defined and analyzed in detail in the paper. The constructed PV source has the advantages of high bandwidth over the switching circuit based PV simulators. The constructed PV source has been used for testing various power electronics converters and various control techniques effectively in laboratory environments for researchers and university students.

“…Therefore, the output characteristics of a PV array under various operating conditions are always simulated by a PV simulator, which can be made by an analog circuit, a digital circuit or an analog and digital hybrid circuit. There are several methods to implement a PV simulator, including: 1) amplifying the output of the current and voltage of a sample PV cell or photosensor diode with a controlled light source imitating sunlight or an LED light emission circuit to simulate variations in sunshine intensity [6], [7] 2) constructing a PV array by taking a PV cell equivalent circuit with analog circuits as a basic unit [8] 3) using a DC power supply controlled by a personal computer (PC) with a data acquisition card or a special real time digital simulator (such as RT-LAB) [9], [10] 4) adopting a unidirectional DC-DC converter with a basic topology controlled by a DSP, a PC, a microprocessor, a microcontroller, or some other [15] 6) using multiple multiphase DC/DC converters controlled by a PC or a DSP as the main circuit of the PV simulator [16], [17] 7) selecting a high frequency PWM rectifier for a three-phase voltage source controlled by the host computer as the main circuit of the PV simulator [18]. Despite achieving adequate simulative effects, most of the PV simulators still exhibit some problems, such as a limited effective working range, bigger ripples of the output voltage and current, lack of systematic modeling and design methods for the controller parameters, lower development efficiency, and so on.…”

This paper presents the design and realization of a digital PV simulator with a Push-Pull Forward (PPF) circuit based on the principle of modular hardware and configurable software. A PPF circuit is chosen as the main circuit to restrain the magnetic biasing of the core for a DC-DC converter and to reduce the spike of the turn-off voltage across every switch. Control and I/O interface based on a personal computer (PC) and multifunction data acquisition card, can conveniently achieve the data acquisition and configuration of the control algorithm and interface due to the abundant software resources of computers. In addition, the control program developed in Matlab/Simulink can conveniently construct and adjust both the models and parameters. It can also run in real-time under the external mode of Simulink by loading the modules of the Real-Time Windows Target. The mathematic models of the Push-Pull Forward circuit and the digital PV simulator are established in this paper by the state-space averaging method. The pole-zero cancellation technique is employed and then its controller parameters are systematically designed based on the performance analysis of the root loci of the closed current loop with k i and R L as variables. A fuzzy PI controller based on the Takagi-Sugeno fuzzy model is applied to regulate the controller parameters self-adaptively according to the change of R L and the operating point of the PV simulator to match the controller parameters with R L . The stationary and dynamic performances of the PV simulator are tested by experiments, and the experimental results show that the PV simulator has the merits of a wide effective working range, high steady-state accuracy and good dynamic performances.

“…For the solution to this problem, a rather large number of research results promote "PV module emulation system" [5,6,7,8,9,10,11], which reproduce the power-generating behavior of the target PV module under different environmental conditions. The benefits of such emulation systems are not limited to the solar energy, but have been demonstrated for other power sources including batteries [12] and fuel cells [13].…”

“…However, mathematical simulation that does not account for real hardware to generate power has a limitation in that we cannot observe the whole system including, for example, DC-DC converters and real load devices. Some recent PV module emulation systems that generate power based on analog circuits have been suggested, including one reported in [5]. Meanwhile, computer-based PV module emulations provide better flexibility based on more elaborated, parameter-adjustable PV models.…”

Photovoltaic (PV) cells are promising endurable renewable power sources that do not include mechanical components, which are subject to wear and tear. However, actual development of a solarpowered system requires elaborated design processes to find the best setup including location determination and development of a maximum power point tracking method, which requires numerous on-site experiments.This paper introduces a versatile PV module emulation system, which can cover a range of different PV modules and environmental conditions. We provide an accurate parameter characterization methodology with nonlinear curve fitting to minimize the model discrepancy over the entire operating range. The proposed PV module emulation system includes a pilot PV cell, temperature sensors, an accelerometer, and a magnetic sensor, and provides features for the PV module characterization and emulation modes. Experimental results show significant improvement in the emulation accuracy, which comes from the advanced PV module characterization method as well as high-precision hardware and control.
