The
simulation process
The input data for
the simulation consists of:
 |
the hydrosystem
structure, namely the system components (nodes, reservoirs, aqueducts,
pumps) and their attributes, and the topology |
|
the hydrologic
time series, either taken from historical records or generated synthetically |
|
the operational
constraints (targets) referring to water consumption, minimum flow
preservation and reservoir storage control |
|
the parameters
of the operation rules for each reservoir |
The simulation procedure
at each time step can be described by the following steps:
Step 1: The
total useful storage of the system is estimated and the target releases
from each reservoir are calculated according to the parametric operation
rules.
Step 2: System's
components are transformed into digraph components and the values of the
digraph attributes (inflows, capacities and unit costs) are specified.
Step 3: The
flow allocation (transshipment) problem is formulated and solved.
Step 4: The
optimal flow values are assigned to the variables of the mathematical
model of the hydrosystem, in order to express real and not ideal magnitudes.
