Special
Features
(i)
Specific/optional consideration of transmission lines
and losses, multiple demand areas, component dependencies,
maximum and minimum monthly plant outputs;
(ii) Detailed
modelling of Power Purchase Agreements and Transmission
Carriage Tariffs in terms of (monthly) fixed, per
MW and per GWh costs;
(iii) Load
dispatch simulations, component scheduling and economic
analysis conducted on a monthly basis;
(iv) Deterministic
or probabilistic load dispatch simulation, with optional
consideration of hydro plant, thermal plant and transmission
line forced outages;
(v) Up to
5 hydrological conditions (hydro plant capacity and
energy availabilities), and 8 load dispatch blocks
(LP);
(vi) Recognition
of differential demand area unserved energy costs
and supply benefits (including exports), and hydrological
condition related preventive rationing;
(vii) Explicit
separation of investment and operating costs, supply
benefits and penalties;
(viii) Fully
annotated input and detailed output files together
with comprehensive graphical presentation facilities.
(ix) 'Mimic
Diagram' playback of system development and load
dispatch results. top
