“…Kawabe K, et al [10] proposed the control strategy of using large-capacity ES batteries for transient stability, but it requires high capacity of ES power supply in the system to implement emergency control of transient stability only by relying on ES power supply. Based on Hamilton system theory, Peng J, et al [11] proposed a coordinated emergency control strategy involving both cutting measures and superconducting energy storage. However, this method is suitable for the instability of generators connected to the same bus.…”

With the development of energy storage technology, energy storage power station has gradually become one of the main means to solve the voltage instability of the main network caused by uHV DC bipolar phase lock. Therefore, energy storage model has become a difficulty in research. Firstly, the structure model of power storage station participating in power grid voltage transient stability control system is constructed, and the control strategy of power storage station is analyzed. Secondly, in the power system analysis software package (PSASP), the ES model of transient voltage stability control is established by using user-defined modules, and each module in the model is introduced in detail, so as to realize the purpose of enhancing voltage transient stability control of energy storage power station connected to the power grid. Finally, the simulation results show that compared with the adjustable camera, the voltage recovery speed is faster when the same capacity ES is connected in the same place. For example, the voltage recovery speed of 110kV bus decreases from 2.42s to 1.69s, and the recovery speed is increased by 30.17%. And PCS of ES power station has enough short time (<1s) overload capacity, then the ES configuration capacity can be less than the camera capacity.

“…With large disturbance, the system operates in an undesirable condition and it may not perform as it is designed to. Besides, non‐linear control, such as variable structure control [2], adaptive control [3, 4], the Hamiltonian method [5], inverse system method [6], H‐infinity control [7] and so on, may perform well in many conditions. However, they need control laws and large amounts of online calculation which make them not so practical.…”

To improve the performance of the governing system as well as the stability of the power system, the authors propose grey prediction extension control (GPEC) in the design of generator governing system. Comparing with the conventional control strategy such as conventional proportional–integral–derivative control and simple extension control, GPEC is more suitable for the complex, huge‐dimension and time‐varying modern power systems. Both a simple hydropower system and a typical multi‐machine system are studied, respectively. The simulation results indicate that the proposed GPEC governor controller performs better in reducing overshoot and adjusting time with superiority in leading the system into a stable state.

To improve the transient stability of power grid, this paper proposes an emergency control strategy considering battery storage to participate in the transient stability of power grid. The phase plane trajectory convexity is used to identify the transient stability of the power grid. After the system is unstable, the dual-machine equivalence is carried out for the multi-machine power system regulated by the energy storage power supply, and the control quantity required by the energy storage power supply to restore the system stability in the single-machine system is calculated. The effectiveness of the control strategy was verified in the EPRI-7 system. The simulation results show that the transient stability emergency control strategy with energy storage power participating in the regulation can effectively improve the transient stability, reduce the emergency control failure, and inhibit the frequency and voltage reduction.
