Abstract
The invention discloses a power feedback control system and method of MGP system, including detecting the actual active power sent 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 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; through the adjustment module adjusts finely the frequency of the converter and adjust the phase difference of frequency modulation to achieve controlling power output, so when the new energy predicts its output power based on power feedback control using MGP before connecting to grid, the output of the control system will not delay and affect the stability and reliability of the control system, ensuring the smooth introduction of new energy grid-connected methods.
