Corrective short-term transmission maintenance scheduling considering post-contingency restoration

If partial maintenance is permitted for those maintenance that is not urgent, it will help alleviate emergency conditions through proper restoration strategy. This letter presents a corrective short-term transmission maintenance scheduling model considering post-contingency restoration of some maintenance transmission lines (STMS-PCR), which allows re-scheduling of the maintenance schedules after contingencies. Numerical tests based on six-bus system show that the STMS-PCR method improves the economics and reliability of power system operations.
