Output fluctuation of renewable energy generation such as wind power generation can lead to extend of tie line flow fluctuation. Therefore, power system transient stability may deteriorate. On the other hand, adjustable speed pumped storage generators have high speed adjusting output capability by ac excitation control with power electronic equipment having high response speed. This paper proposes output control of adjustable speed pumped storage generators using power flow fluctuation to enhance transient stability by suppression fringe component of tie line flow fluctuation. The feature of this control method is that, if transient stability is deteriorated by fringe component of power flow fluctuation, adjustable speed pumped storage generators choose fringe suppression control. Otherwise, adjustable speed pumped storage generators choose load frequency control. In order to check the effectiveness of the propose approach, numerical simulations are conducted on the interconnected 2-area power system model. The result shows that the proposed approach can suppress fringe component of tie line flow fluctuation and enhance transient stability.
