The theory of voltage source voltage control technology is been researched in this paper. According to the basic principle with regulation of active power to frequency and reactive power to amplitude in the parallel operation of the inverter, and this principle is is applied to photovoltaic grid inverters. The active and reactive power is independent controlled, so that the inverter output power control is much more flexible. Voltage control algorithm is discussed in detail, gives the calculation method of the Id, Iq and sine wave synthesizer. The simulation model is established in Matlab/Simulink and the experimental verification, simulation and experimental results show that the Voltage Source Voltage Control technology is feasible.
