Power generation system

The invention provides a power generation system. The power generation system can comprise an integrated system and a power transformation system. The integrated system can comprise a plurality of inverters and a plurality of first switches, and the plurality of inverters and the plurality of first switches are connected in series in a one-to-one correspondence mode. Each inverter converts direct current from a direct current source into alternating current and outputs the alternating current to the corresponding first switch. The plurality of first switches gather alternating currents from the corresponding inverters and output the alternating currents to the power generation system, and the plurality of inverters and the power transformation system are isolated. And the power transformation system adjusts the voltage value of the collected alternating current and outputs the voltage value to a power grid. According to the invention, a plurality of direct current sources can be accessed to a power grid, comp
