Abstract: This paper proposes operation modes of a typical solar power generation system. It is having solar as renewable energy source, storage battery and load, is connected to AC grid. This system uses converters and switches, and by controlling them it can be operated in different modes. In this paper, the behaviour of system for every transition of mode is explained, by controlling the switching devices, which is tested in Simulink package and results assure that power is supplied to load, and balanced forevery mode of operation.
Keywords: Operational Modes, Solar Power Generation, Storage Battery, AC grid.
