DETERMINATION OF NEEDED FACTS CONTROLLERS THAT INCREASE ASSET UTILIZATION OF POWER-SYSTEMS

The paper presents an approach far identifying the most effective Flex ible 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 continua tion 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 h elpful in coordinating the functionality of FACTS Controllers to enhan ce power system dynamics.
