Applied supply side Management of electric Energy in Supply side. This is prior in order to
optimalize of using Hydro generation so it could operation as maximal as possible in the peak of system
loading. In this WG] eficiency of using minimum fuel as expected can be occur in Operation the
Thermal Generation.
In order to have an optimum .system, in Electric Power System that consist of unit Hydro Generation
and other Thermal Generation such as PLTU1 PLTP, PLTGDI PLTG. A loading regulation is necessary
to build in an electrical power generation, in order to have an optimum operation for electric power
system, in which minimum fuel cost in operation electric energy need all. It is important to do because the
electrical power generation serves electric power loads, that always change by the time, and also result
fuel-cost per unit time in rupiahs pers hours, changes by the time.
The cost of Electrical Power System operation is set as the goal to be minimized and the junction of
operation cost will be change. Gradient Method will be used in order to solve this hind of matters. The
optimum of generation regulation in this paper was restricted as generation regulation of real power
whenever the optimum generation using this gradient Method is more profitable then using merit order
method technically and economically.
In this case Computer program will be Applied using computer simulation in which Borland Delphi
release 7.0 as computer language programming, in order to to find an optimization of operation system
hydro-thermis power generation. As the result of Computer simulation program, is picture, table or chart
that would be easier to be understood.
