Determination of needed FACTS controllers that increase asset utilization of power systems

The paper presents an approach for identifying the most effective flexible AC transmission system (FACTS) controllers, locations, types and ratings that increase asset utilization of power systems. The approach is a combined static/dynamic procedure based on the use of a continuation power flow, an optimal power flow and an eigenvalue analysis. The application of this approach on a representative studied transmission system has resulted in an increase of the maximum stable loadability limit by 6.7%. The paper finally shows that the proposed approach is helpful in coordinating the functionality of FACTS controllers to enhance power system dynamics.
