Short-term transmission line maintenance scheduling in a deregulated system

In this paper we present a decomposition approach based on duality theory f or line maintenance scheduling with transmission and voltage constraints. T he given formulation consists of a master program and sub-problems with two independent programming. In the master problem, maintenance problem is sol ved and in the subproblems, transmission and voltage problems are solved in dependently, Since canceling a transaction or purchasing reactive power rel ates to the loss of revenue, the trade-off between maintenance cost and rev enue loss will be optimized in the proposed method, The test results on the modified IEEE 118-bus system demonstrate that limits on transmission and v oltage affect the line maintenance scheduling and increase the maintenance cost. While introducing the loss of revenue as one of the objective functio ns, the proposed method is flexible enough to accommodate various pl icing objectives and methods.
