(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
