3.2 LONG RANGE HYDRO THERMAL SCHEDULING

Let a power system consist of one large hydel plant and one thermal plant say. The two plants cater to the total system load PD.

Fig 3.1 A power system consisting of a hydel and a thermal Plant.

The hydro plant can generate power PH more than power demand PD for a limited time t. That is,

 

PH,max ≥ PD

 

However, the energy available from the hydro plant is insufficient to meet the load because of the water constraints.

Let tmax be the number of hours required for an optimization solution (week/month/year) say.

The hydro energy produced is less than total energy required. The difference in energy shall ...
