OPTIMIZATION MODEL FOR UNIT COMMITMENT IN POWER OPERATION PLANNING
The unit commitment in power operation planning concerns the scheduling of start-up/shut-down decisions and operation levels for power generation units such that the fuel costs over some time horizon are optimal. This paper proposes an optimization model to solve for the optimal daily and weekly power operations. The complex nature and diversity of generation, transmission system, and distribution of electric power leads to a variety of issues in mathematical models. The model composes of the combination of the thermal, hydro, gas turbine and combined cycle generators. Each generator type has different specific technological design, fuel type, fuel consumption, fuel capacity, heat rate, and general unit parameters. The general unit constraints include the minimum uptime, minimum down time, ramp-up/ramp-down constraint, and minimum spinning reserve. We consider a daily and weekly planning horizon with the time slot of 30 minutes and 1 hour respectively. The objective function is to minimize the total cost of fuel used for power generation. This paper presents the formulation of a mixed integer linear programming for this problem. The model is coded with ILOG CPLEX and tested with various seasonal demands to observe the behaviour of the model. Managerial insight is drawn from the control of the hydro generator and pumped-storage plant.
