The invention discloses a PQ control method for active power distribution network port, the method comprises the following steps: (1) collecting three-phase voltage and current input at a the active power distribution network port; (2) calculating active power PPCC and reactive power QPCC inputted at the active power distribution network port according to the collected voltage and current obtainedin the step (1); (3) calculating difference [delta]PPCC between a set port reference active power P*PPC and the active power PPCC, inputting [delta]PPCC into the PI control module to obtain a port active power deviation compensation delta PPCC; (4) calculating difference [delta]QPCC between a set port reference reactive power Q*PPC and the reactive power QPCC, inputting QPCC into the PI control module to obtain a port reactive power deviation compensation delta QPCC; (5) respectively transmitting the port active power and the reactive power deviation compensation delta PPCC and delta QPCC toeach distributed power supply; (6) generating an active control signal by the distributed power supplies; (7) generating a reactive control signal by the distributed power supplies; and (8) inputtingactive and reactive power control signals to the respective inverters by each distributed power supply as control inputs.
