Unified modeling of UPFC-SMES in power system application

These instructions give you basic guidelines for preparing papers for conference proceedings. This paper discusses the modeling issues of incorporation of a Superconducting Magnetic Energy Storage (SMES) coil into UPFC for application in power systems. A UPFC can only absorb/inject reactive power and, consequently, is limited in the degree of freedom and sustained action in which it can help the power grid. The addition of energy storage allows the UPFC to inject and/or absorb active and reactive power simultaneously, providing additional benefits and improvements in the system. Detailed model of UPFC based on switching function and dynamic model of SMES are considered in modeling. Finally a steady-State load flow model of UPFC/SMES is presented.
