| Abstract: | The control strategy of the three-phase PV grid-connected system is analyzed and studied in simulative experiment. First, a mathematical model of solar ceils is established, then the algorithms based on perturb ＆ observe to track maximum power point is used. Secondly, the structure of three-phase PV grid-connected system is introduced, and the space vector SVPWM controller is used to control the grid-connected inverter. Finally, the simulative results on Matlab/ Simulink software show that SVPWM inverter control strategy is superior to the traditional hysteresis current inverter control strategy. |
