Abstract

One of the most important issues which affects the power generation scheduling is the Start-Up and Shut-Down Costs of generation units. The amount of fuel consumed by a thermal unit from Starting up until synchronization with the power grid has been considered as the Start-up cost. While the fuel consumed for maintaining the thermodynamic requirements have been categorized as shut-Down Costs. These Start-Up and Shut-Down Costs are however for a hydroelectric generating unit due to independency in fossil fuels. Yet the degradation of equipment of such units is considerable due to the frequent Start-ups and shut-downs. In this paper, a fair methodology is provided for estimation of these costs and by implementing a Mixed-Integer Non-linear programming framework the effects of implementing these costs in the generation scheduling are studied. The decision variables in this framework were the optimum operating points of all generation units in the planning horizon. Also, Start-Up and Shut-down states for such generating units are considered as one control variable in the optimization problem. In order to evaluate the effectiveness of the proposed model, a typical hydro-thermal test system is accepted including 9 thermal and one hydroelectric unit. Different scenarios are evaluated in this paper to assess the effects of Start-Up and Shut-Down Costs in the short term planning. The simulation results confirmed that including these costs in the generation scheduling can dramatically reduce the total Start and stop actions.
