| Abstract: |
| Grid-forming and grid-following power electronic devices have heterogeneous frequency regulation characteristics, which leads to complex dynamic interaction mechanisms in the inertial response stage of AC/DC hybrid power systems composed of the two types of devices. The traditional matching principle of inertia parameters is difficult to optimize the frequency response of the system. The system inertia response matching problem of power electronic devices is expounded, and the existing frequency regulation control methods of voltage source converter is summarized. The research status of configuration problem of power electronic device system is combed from three aspects: power frequency response analysis method, frequency regulation power allocation principle and frequency response characteristics. The research idea of unified modeling and inertia matching problems is put forward, aiming at improving the frequency stability of low inertial power system through inertia supporting power matching control and providing basic theory and key technical support for friendly grid-connection of high-proportion power electronic devices from the system level. |
