“…The paper focuses on presenting the method for PV systems testing with the use of real-time simulations in FPGA chip. In [7][8][9] such method was presented for PV systems components simulation, in [10][11] for multilevel converters simulation, in [12] for the electrical machine modeling, in [13] for induction motor control investigation and in [14] for permanent magnet motor drive simulation. We present results from modeling typical components for single phase PV systems (PV source, dc-dc boost converter, single-phase inverter, ac filters, operation of the grid connected inverter in closed system, regulation of voltage in the boost converter and the MPPT realization).…”

Abstract. The paper presents a method of investigation of grid connected systems with a renewable energy source. The method enables fast prototyping of control systems and power converters components by real-time simulation of the system. Components of the system such as energy source (PV array), converters, filters, sensors and control algorithms are modeled in FPGA IC. Testing the systems before its practical application reduces cost and time-to-market. FPGA devices are commonly used for digital control. The resources of the FPGAs used for preliminary testing can be sufficient for the complete system modelling. Debugging tools for FPGA enable observation of many signals of the analyzed power system (as a result of the control), with very advanced triggering tools. The presented method of simulation with the use of hardware model of the power system in comparison to classical simulation tools gives better possibilities for verification of control algorithms such as MPPT or anti-islanding.

“…It can be more useful than PC-based simulations for verification of the operation of a targeted controller solution with a real-time object. Algorithms typical for PV systems, such as MPPT (Maximum Power Point Tracking) or anti-islanding [4] can be very effectively analyzed in an HIL system. Similarly, a problem of partial shading [24], of PV can be effectively tested due to the complicated control of the integrated components.…”

This paper presents a novel, low-complexity method of simulating PV source characteristics suitable for real-time modeling and hardware implementation. The application of the suitable model of the PV source as well as the model of all the PV system components in a real-time hardware gives a safe, fast and low cost method of testing PV systems. The paper demonstrates the concept of the PV array model and the hardware implementation in FPGAs of the system which combines two PV arrays. The obtained results confirm that the proposed model is of low complexity and can be suitable for hardware in the loop (HIL) tests of the complex PV system control, with various arrays operating under different conditions.
