In recent years, the requirement for water resources in Taiwan
is getting
increasing. However, because of the elements of natural
environment,
there are many problems to arrange and make use of the present
water
resources. Also, it is hard to search for new reservoirs and
difficult
to build new reservoirs. This makes the problem more
complicated.
Therefore, how to arrange and make good use of present water
resources
becomes the important way to solve the problem.
The rule-curve of De-Ji Reservoir uses generating electric power
as
the main operating goal. Therefore, it easily causes serious
drought in
downstream area or drought focusing on certain period of time.
This
condition is even more serious in the year lacking of water.
This
research uses grey programming model to improve the drought
phenomenon.
This research, according to the 30-year historical flow records
of De-Ji Reservoir, firstly sets up Thomas & Fiering''s theorem
of
flow synthetic pattern, which uses 10-day as a unit, and this
research
also uses grey stochastic dynamic mold to set up reservoir
operating
model. This research deals with policy by FSDP and expands the
objective function of traditional dynamic programming to
establish the
grey programming model of De-Ji-Reservoir. Moreover, comparing
with the historical results in the same conditions, it
investigates
the historical flow records of abundant water, average water and
low
water and compares the conditions of yearly electric power and
drought.
The results of this research in the year of abundant water,
average
water and low water all can effectively avoid the abnormal
drought
condition which is resulted from the rule-curve of De-Ji
Reservoir.
Comparing with past research records, the general profit has
obviously
increased. In the practical usage, the grey programming model
has its
simplicity and increases its feasibility for long term operation
of
reservoir.
