Special
Features
(i)
Specific (optional) consideration of transmission
lines (including losses), multiple electricity and
water demand areas, monthly maximum and minimum plant
outputs;
(ii)
On screen definition of system components and configuration
('drag and drop');
(iii)
Coincident optimisation of water flows (reservoir
releases), generation plant load dispatch and aqueduct & transmission
line flows;
(iv)
Reservoir operating policies defined by calendar
weekly or monthly varying long-term stored water
values;
(v)
Electricity demands, water demands and inflows can
be input as seasonally varying (profiled) quantities
or as time series;
(vi)
Up to 24 load dispatch blocks, with the facility
to specify individual minimum and maximum generating
plant outputs by block;
(vii)
Explicit consideration of demand area dependent supply
deficit costs and preventive rationing measures;
(viii)
Real-time graphical outputs showing user selected
(daily) reservoir contents, generating plant outputs,
river reach and transmission line flows.
(ix)
Automatic storage of results in MS-ACCESS database
format for subsequent viewing and retrieval.
(x)
Calculation of marginal costs by load block at
electricity demand centres and transmission nodes,
and at water demand areas.
(xi)
Mimic diagram displays of simulation results. Average,
daily and individual load block values can be shown.
(xii)
Graphical, tabular and spreadsheet compatible file
outputs for any combination of simulation time
series values.
