A LP and MILP methodology to support the planning of transmission power systems

The paper describes four optimization solutions that can be used to support the transmission system planning. The problems are focused on the identification of the primary transmission system operations that optimize the power flows on the transmission lines. The approaches are based on a DC model of the transmission system and the optimization problems can be solved recurring at LP and MILP. The mathematical model and the optimization problems have been described in detail, reporting a list of applications that can be handled by the proposed methodology to evaluate the effects on transmission and generation expansion. A 9 bus test grid has been used to support the methodology explanation.
