Application of SMES coordinated with solid-state phase shifter to load frequency control

This paper proposes a sophisticated application of SMES to load frequency control (LFC) in an interconnected power system. The SMES is coordinated with a solid-state phase shifter to enhance the LFC. The frequency control concept and control design of a SMES coordinated with a phase shifter are presented. Numerical results demonstrate the significant effects of LFC by the proposed control and the economical advantage of MJ capacity of SMES.
