The maintenance schedule optimization in an interconnected power system using the levelized risk method

This paper illustrated power system maintenance schedule optimization under the constraints of system interconnection by using the levelized risk method on the model for the five equivalent generating units. First, parallel operation of the assisting system´s capacity outage table and the load outage table and then series operation with tie lines´ outage table are obtained. Procedures for maintenance scheduling are explained and an iterative solution to the maintenance problem of the interconnected power system is realized in theory by the numerical recurrent convolution method.
