Abstract: The invention discloses a power feedback control system and method of MGP system, including detecting the actual active power delivered by the generator to the grid through the measurement and calculation module; making a difference between the measured active power and the given active power; calculating the frequency regulation amount through the PI regulation module according to the difference, and taking it as feedback; calculating the frequency reference value of the converter in the control system; and fine tuning the frequency of the converter through the PI regulation module; regulating the phase difference through frequency modulation; realizing the goal of controlling the power output, so that when predicting the output power of new energy before MGP is connected to the grid based on power feedback control, the output of the control system will not be delayed and the defects that affect the stability and reliability of the control system will not appear, to ensure the successful introduction of new

Abstract: The invention discloses a method for MGP new energy grid-connected control, wherein, the synchronous motor is connected to a synchronous generator; the new energy module drives the synchronous motor to rotate through a frequency converter; the frequency converter controls the power transmission; and the synchronous motor drives the synchronous generator for grid connection. The present invention has the beneficial effects that: the control method and system provided by the invention can improve the stability and reliability of the grid.
