Power flow control of isolated wind-solar power generation system for educational purposes

In this study, the electric energy required for feeding of small power receivers at two laboratories of Afyonkarahisar University Electric Education Department is met by hybrid wind-solar power generation system. For this purpose, 600 W 3-phase permanent magnet synchronous generator (PMSG) based wind power generation system (WPGS) and solar power generation system (SPGS) consisting of 190W 3 pieces mono crystal solar panel are combined to build a 1170W wind-solar hybrid power generation system. Besides, to store the consumption surplus 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 are installed on the wind-solar hybrid power generation system (WSPGS). Then, the block diagrams of the system elements forming the hybrid power generation system and SimPowerSystems in the Matlab/Simulink are used to realize the simulation of the wind-solar hybrid power generation system with battery support. When the curves obtained from the simulation results are examined, it is determined that the electrical and mechanical magnitudes in parallel to the dynamic behavior of the installed hybrid power generation system are so similar.
