Analysis and Optimization of Frequency Support Characteristics for Grid-forming VSC-HVDC Transmission Systems of Large-scale Renewable Energy Bases in Gobi Desert and Other Arid Areas
With the increasing installed capacity of renewable energy and the rising proportion of DC feed-in year by year
the frequency stability issue of the receiving-end power grid has become increasingly severe. The grid-forming voltage source converter based high-voltage direct current (VSC-HVDC) system can provide frequency support for the power grid and enhance system frequency stability. Considering the frequency support characteristics of grid-forming VSC-HVDC
DC system parameters and frequency response characteristics of the AC power grid
a system frequency response model incorporating the support characteristics of the VSC-HVDC system is established. The impacts of major system parameters and control parameters on the frequency regulation characteristics are analyzed. A frequency support strategy based on linear active disturbance rejection control (LADRC) is proposed to improve the adaptability of grid-forming control
and a parameter tuning analysis method is provided. Finally
a grid-forming VSC-HVDC transmission system in Gobi Desert and other arid areas is built on the PSCAD/EMTDC simulation platform. The system frequency model considering the frequency support characteristics can accurately depict the frequency response. The proposed control strategy can significantly reduce frequency deviations and enhance the system frequency support capability and adaptability.
