This paper presents a modeling framework for operations planning for generation and transmission for a period of a year or few months that incorporates (in an approximate way) the dynamic constraints on generator output and the static transmission constraints. The model is capable of performing the following tasks: generation scheduling, interutility transmission scheduling, maintenance scheduling, fuel allocation to thermal/nuclear plants, reactive power planning, DSM and nonutility generation purchase planning. The model checks the operating feasibility of the long term planning decisions by unit commitment and OPF modules in an interactive way. There is a feedback mechanism to modify the long term generation and transmission schedule to reflect the operational feasibility of the long term planning exercise. The model makes use of compromise programming to perform multiobjective analysis. A case study for a 120-bus test system (four area IEEE 30-bus systems) is carried out to illustrate the application of the proposed modeling framework
