Generation and transmission equipment maintenance scheduling with load transfer

Generation and Transmission equipment maintenance scheduling (GTEMS) involves many aspects in power systems operation. Unreasonable arrangements will bring a lot of adverse effects. This paper studies the preventive maintenance. Through the regular inspection (preventive maintenance), the equipment's life span can be extended. This paper develops an optimal model of multi-objective optimization model for generation and transmission equipment maintenance scheduling considering load transfer in case of heavy load or equipment outage. Four objectives are considered for optimal maintenance scheduling. The solution method is a relatively dominant objective of immune genetic algorithm. The proposed multi-objective optimization GTEMS model and approach are tested on IEEE 30 bus system. The test results show the effectiveness of the paper.
