Abstract:
In this dissertation vn Optimal Scheduling of Hydro-Thermal Systems, various aspects of scheduling i.e.
locati fg both active and reactive power to hydro and thermal units in a combined system have been discussed so as to achieve maximum availability of generating capacity, obtain energy at minimum cost and utilise the resources most effectively.
Optimal scheduling of power in hydro thermal systems is more involved as spared to optimal, operation of an all thermalsystem. Optimal operation of a'herinsl system is a static optimisation problem i.e. the objective
is to mixd .se instantaneous fuel cost which is ction - of type, size and loading of the thermal unit subject to the equality constraints of the power system (Demand and losses = Generation) as well as inequality constraints imposed by the equipment ratings. In case of operation of hydro thermal systems, the problem is of dynamic optimisa Lion i.e * one has to take into account the water usage policy over a period for optimum benefits..
