“…Further, micro-controllers and processors have also been exploited in designing the PV emulator systems [14], [15]. Applications of different real time controllers like Sitara Cortex 9, dspace, FPGA and ARM controllers for PV emulator systems have been reported in literature [16], [17]. However, cost and complexity of PV emulator system rises with the utilization of the above mentioned real time controllers.…”

Threatening environmental effects have forced the community to utilize green and clean alternative options for the generation of electric power. As a matter of fact, solar energy is a critical source of energy; so the demand for creative research is its peak. However, performing real time experiments on solar PV systems is limited by cost, manufacturing, weather constraints and requirement of large space. Thus an equivalent solar energy photo voltaic (PV) system is required for experimental verification and analysis based on precise simulations. In this research work a PV emulator system based on a buck converter is realized. The main objective of PV Emulator is to replicate the characteristic curves (I-V, P-V) of the real solar panel. In order to compensate the variations in both the load and the parameters of power stage, a robust control system is required. A fractional order sliding mode control scheme (FOSMC) has been designed and investigated in this research work. Results have proved the superior performance of the FOSMC as compared to other classical sliding mode control method. The FOSMC controller and PV emulator are implemented using rapid prototyping technique. INDEX TERMS Renewable energy, photo voltaic emulator, control system, fractional order control.

“…These include implementations in which the I-V profiles are generated through platforms such as FPGAs [16,17] , dsPIC [18] and labVIEW software [19][20][21][22]. The output is then produced by controlling dc-dc converters such as flyback [18,20] and buck converters [17].…”

Maximum Power Point Tr acking (MPPT) is an essential element of a PV system. Bench power supplies provide a reasonable approximation of solar panel behavior and can be used for initial testing. However, detailed testing with actual solar panels is required to accurately establish the performance of MPPTs. This could be a difficult and time consuming task, especially for medium and high power ratings, owing to constraining factors such as panel sizes, panel availability, testing area, daylight hours etc. An alternative to this is the use of Solar Panel Emulators (SPEs) which mimic the behavior of the panel with a reasonable accuracy. These emulators can be used to test circuits indoors for a variety of power ratings and I-V profiles while being significantly smaller in size. In this paper, we have designed and implemented a medium power SPE based on diode approximation model. By minimizing component usage, the cost of the emulator is largely reduced. The proposed circuit is simulated and then tested with loads of up to 60W with satisfactory results.Index Termsdiode model, implementation, low cost, solar panel emulator.
