Abstract：For cross-regional asynchronous-tied grid of voltage source converter based high voltage direct

current（VSC-HVDC）transmission system，a frequency support control strategy for energy storage devices based

on 5G communication was proposed. Firstly，the frequency-voltage droop control and frequency restoration control

strategies were designed for the sending-end and receiving-end VSCs respectively，so that the VSC-HVDC could

reflect the grid frequency fluctuations on one side to the other side. Then，a power synchronization control strategy

was designed for the VSC at the energy storage interface of 5G base station，enabling it to adaptively adjust output

power based on AC frequency. Furthermore，a cross-regional frequency support logic for energy storage devices

based on 5G communication was proposed. This logic selected the control mode of the VSC-HVDC based on the

degree of frequency deviation in the sending-end power grid. At the same time，based on the remaining state of

charge of the energy storage devices at the 5G base station，the energy storage devices with corresponding

frequency regulation capabilities were activated to participate in cross-regional frequency support. The simulation

results verify the effectiveness of the proposed control strategy in enabling energy storage to participate in crossregional frequency support and improving the frequency stability of the power grid.
