Structural control of electric power networks for transient stability

This paper presents a sensitivity-based approach for structural control of electric power networks using FACTS (flexible AC transmission system) devices in order to improve the transient stability margin for one controlling unstable equilibrium point (u.e.p). It is comprised of the sensitivity analysis of critical energy of the TEF (transient energy function), network control strategy and evaluation. A related practical application to a 39-bus test system follows and shows that the structural control of power networks is effective for the enhancement of power system transient stability. >
