Goal. Development of the experimental installation for testing of the software and hardware tools of management of a photovoltaic system of a local facility connected to the grid, which, along with checking its operability, will allow analyzing the operation and adjusting the settings of systems with different parameters under different weather conditions, load schedules and operating modes. Method. Experimental research with preliminary justification of settings based on calculations and simulation data obtained in the Matlab software package. Results. The structure and experimental installation on the base of the photovoltaic system with storage battery and using a photovoltaic battery emulator with software control of generation and load power were developed. The software modules of the system have been developed. According to the results of the simulation, the moments of time are determined when the operating mode is switched in the experimental setup. The experimental setup was tested in static and dynamic modes. Static tests were aimed at checking the functioning of the photovoltaic battery emulator in accordance with the specified solar radiation power and the temperature of the photo module, as well as checking the correctness of the model used in the program. Tests in statics with fixed parameters and in dynamics in the daily cycle, in general, confirmed the efficiency of the proposed solutions. Scientific novelty. The method of experimental research in the daily cycle of photovoltaic systems control with the use of software-controlled emulators of a photovoltaic battery and load with power and time scaling was developed. This, along with the acceleration of the experiment, allows us to estimate the effectiveness of the tested systems at different ratios of system parameters and adjust the functioning algorithms. Practical importance. The proposed solutions for the implementation of the experimental installation allow minimizing material costs and time costs in the process of testing and development of software and hardware control tools of a photovoltaic system with storage battery.
