Abstract

ABSTRACT： The variable speed wind turbines with virtual inertia can improve the system frequency stability, and the power angle transient stability of the power generation system will undergo significant changes due to the change of controllable inertia. Firstly, this paper derives the mathematical model of the interconnected two-regional power grid with wind power at both ends. By theoretically analyzing the influence of wind turbines inertial adjustment on the interconnected system transient energy in two-regional power grid, the system power angle transient stability level is evaluated. Then, for improving the adverse effects of the wind power inertial control on the system power angle transient stability, this paper proposes a variable virtual inertia control strategy of doubly fed induction generator (DFIG) based on transient energy. By rapidly adjusting the inertias at both sides of two-regional power grid, it not only can avoid the power angle instability caused by fast inertial response after failure, but also improve the transient stability of the system. Finally, a simulation model of two-regional interconnected system with high wind power penetration is established to verify the effectiveness of the proposed control strategy.
