Integrated generation capacity and transmission network expansion planning with superconducting fault current limiter (SFCL)

As the size of a power system continues to expand, generation capacity and transmission network expansion may be restricted by the fault current limit. Superconducting fault current limiters (SFCLs) are one of the promising fault current limiting technologies that could have potential for greater use in power systems. The installation of SFCLs in a power system is expected to help reduce the fault current levels. This paper presents a fault current constrained planning method for integrated generation and transmission expansion considering SFCLs. In this paper, the fault current constrained planning problem of the integrated generation and transmission expansion is formulated as a co-optimization problem considering SFCLs. Results of a numerical simulation are presented to show the effectiveness of the proposed integrated generation and transmission expansion planning method considering SFCLs.
