In order to make the new energy terminal of voltage source converter based high voltage direct current (VSC-HVDC) interconnected system with new energy access participate in the frequency adjustment of AC network as a whole, an active power control strategy for the converter station terminal with frequency-voltage dead zone is proposed. This strategy using frequency-voltage dead-zone limit and real-time control of the output power of VSC-HVDC. When the frequency of AC network changes on the system side, the kinetic energy reserve of the wind rotor increases or decreases the active output in a short time, so that the speed of the wind Turbine decreases or increases. By increasing/reducing the kinetic energy reserve in the rotor of the wind motor, the unbalanced active power at the AC system terminal can be alleviated, through the VSC-HVDC interconnected system to make frequency response to participate in frequency modulation.Finally, simulations with PSCAD/EMTDC verify that the proposed control strategy is able to enhance the frequency stability of the VSC-HVDC interconnection system with new energy access.
