Abstract

In this paper, an isolated wind-photovoltaic hybrid power system with battery storage will be presented that can supply electricity to  two laboratories with a capacity of 1072 W peak electrical power depending on the need at the laboratory illuminating where used.A 1170W hybrid power generation system consists of a 190W 24V 3 pieces mono crystal solar panel and 600W 3-phase permanent magnet synchronized generator (PMSG) wind power generation system, rotating 3600 according to direction of wind, was installed.Besides, to store the consumption excessive electric energy or in case of lack of generation, to ensure energy continuity via renewable power system, 100 Ah 12V 6 pieces gel jeep cycle accumulator groups were installed on the wind-solar hybrid power generation system.  In the hybrid power generation system, the data record in 10 second intervals (as kWh) was realized separately from each generation system. Monthly totals of obtained data were arranged separately in tables and graphics.When these obtained data were analyzed, the monthly total electric energy generated by the hybrid power system and monthly total electric energy used by consumers were compared according to the 6-month data. As a result of the comparisons made, it was determined that the generation power of battery storage hybrid power generation system was above its consumption power and at the same time, consumption excessive electric energy was stored in proportional to its battery capacity.
