AI Technical Summary

Technical Problem

In existing technologies, the dynamic characteristic mismatch between hydrogen energy systems and battery energy storage systems poses challenges to traditional coordinated control methods in achieving stable and efficient system operation, especially under rapid disturbances, which may lead to computational delays and the risk of subsynchronous or supersynchronous oscillations.

Method used

The microgrid control system using hydrogen energy buffer batteries achieves autonomous adjustment and global coordination of heterogeneous energy storage units by deploying a local adaptive virtual impedance controller and a wide-area coordinated signal generation unit. It uses local electrical quantity monitoring and global variable calculation to calculate the virtual impedance value and dynamically adjusts control parameters to match the response time of different energy storage systems.

Benefits of technology

It achieves natural decoupling of the control loop, eliminates subsynchronous or supersynchronous oscillations, improves the stability margin and response efficiency of the system, and ensures the safe and stable operation of the system under rapid disturbances.

Abstract

The application relates to the technical field of smart grid control systems, and discloses a micro-grid control system using hydrogen energy buffer battery energy storage, which comprises a hydrogen energy subsystem and a battery energy storage system, the hydrogen energy subsystem and the battery energy storage system are connected to a direct-current bus or an alternating-current bus of a micro-grid through a current transformer, a local adaptive virtual impedance controller arranged in each current transformer, and an independent wide-area coordination signal generation unit; the local adaptive virtual impedance controller is used for executing local fast autonomous control. The micro-grid control system using hydrogen energy buffer battery energy storage can independently adjust a dynamic virtual impedance according to local electrical quantities, and realizes natural decoupling of a control loop from a physical layer. Self-organization based on local information can actively avoid control bandwidth overlap, so that the root cause of subsynchronous or supersynchronous oscillation is fundamentally eliminated, and the stability margin of the system is significantly improved.
