Efficiency of photovoltaic modules operation modes in arctic conditions

Photovoltaic modules in hybrid power plants are increasingly used to supply power to isolated consumers, for example, those in the Arctic Zone. The control systems operating modes and settings selection, which ensures the efficient solar power plant operation, is of high importance and requires comprehensive research in the climatic conditions of the Arctic Zone. The paper presents the results of experimental studies into the efficiency of the operating modes employed at a solar power plant located in the city of Arkhangelsk. Autonomous operation mode, forced generation mode and pumping mode are analyzed. Recommendations on the use of these modes with effective settings parameters are suggested.
