An MILP Approach to Scheduling of Expansion and Maintenance Measures in Electrical Transmission Grids

The increasing share of generation based on renewable energy sources and the resulting demand for transport capacities make grid expansion necessary. In order to conduct structural measures on the transmission grid, in many cases, the corresponding transmission lines need to be shut down. Measures i...

Summary:The increasing share of generation based on renewable energy sources and the resulting demand for transport capacities make grid expansion necessary. In order to conduct structural measures on the transmission grid, in many cases, the corresponding transmission lines need to be shut down. Measures include grid expansion and maintenance, with the completion of expansion measures changing the topology of the grid and allowing additional operational degrees of freedom. This contribution presents a novel approach based on mixed-integer linear programming to scheduling grid expansion and maintenance measures while optimizing grid operation. The method is applied to a synthetic 120-bus test system and the results show that suitable schedules can be obtained.
