ORSIM; optimizing utility generation planning. [IBM360,370,303x; FORTRAN IV (95%) and Assembly language (5%)]

Technical Report ·
OSTI ID:6207398
ORSIM is an electric power generating system integration model which simulates the multi-year operation of a mixed power system consisting of fossil, nuclear, hydroelectric, and pumped-storage units. For any specified refueling schedule for nuclear units and future load forecast, 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 scheduled introduction and retirement of generating stations. The model determines a maintenance schedule for the non-nuclear stations (nuclear stations are maintained during refueling outages) and the optimum allocation of energy-fixed nuclear and hydroelectric resources. It calculates the expected energy generated by each station in the system, by period over the planning horizon, based on input or calculated incremental operating cost. It also calculates the expected loss-of-load probability and unserved energy demand for each period in the planning horizon. An optimum operating plan, designed to minimize the discounted total production cost, is then calculated, as are the costs of operating each station in the system and the discounted total production cost for the derived plan of operation.IBM360,370,303x; FORTRAN IV (95%) and Assembly language (5%).; OS/360,370; 750K bytes of memory are required for execution, and card as well as printer output is generated.
