Scheduling of generation in deficit power systems

Scheduling studies are carried out on a deficit hydrothermal power system. The problem is formulated as one of minimizing the severity of power cuts. The maintenance schedule of the thermal plants is selected by minimizing its deviation from an ideal, unrealizable schedule. The thermal plants are production-scheduled on the basis of their maintenance schedule. The influence of the stochastic nature of the load and the hydro inflows on the scheduling is evaluated. The hydro plants are scheduled through the extension of the techniques of the surplus case. Illustrative studies on an actual deficit hydro-thermal system are described
