Oak Ridge System Integration Model (ORSIM) for optimization of utility generation planning

Technical Report ·
OSTI ID:7367685

An electric power generating system integration model has been developed which simulates the multi-year operation of a mixed power system consisting of fossil, nuclear, hydro, and pumped-storage units. This model has been given the name ORSIM, an acrosym derived from Oak Ridge Systems Integration Model. For any specified refueling schedule for nuclear units and forecast of future load, the model determines a plan of operation for the system which attempts to minimize the total discounted operating cost over a specified study period. The analysis considers the effects of forced outages, spinning reserve operating constraints, and schedules introduction and retirement of generating stations. An optimum operating plan, designed to minimize the discounted total production cost, is calculated, as are the cost of operating each station in the system and the discounted total production cost for the derived plan of operation. 13 references.
