Long-Term Transmission Maintenance Scheduling

Abstract

Most of the maintenance scheduling methods available in the literature consider only the generation system and do not take into account the maintenance of transmission lines. Transmission line maintenance scheduling ought to minimize the total maintenance cost and TRANSCOs’ loss of revenue while satisfying the reliability and network requirements. It is essential for TRANSCOs to include forced outages of their components in transmission maintenance scheduling, which may otherwise result in unrealistic reliability indices. The proposed transmission maintenance schedule will be submitted by TRANSCOs to the ISO, which will check network flow constraints based on the generation information provided by GENCOs. The methodology for the solution of this long-term transmission maintenance problem is discussed in this chapter.
