The Long-Term Maintenance Scheduling in Distribution System: PEA Case Study

This paper presents the long-term maintenance scheduling for the Provincial Electricity Authority of Thailand (PEA) distribution system. The objective is to minimize the customer outage cost and utility reliability cost while maintaining the system reliability and considering the limited maintenance resource. The problems have been solved by mixed-integer linear programming (MILP). The algorithm is performed on 28 distribution feeders located in the Southern area of PEA to demonstrate the results.
