­­SDDP is a hydrothermal dispatch model with representation of the transmission network used for short, medium and long term operation studies. The model calculates the least-cost stochastic operating policy of a hydrothermal system, taking into account the following aspects:

    operational details of hydro plants (water balance, limits on storage and turbined outflow, spillage, filtration etc.);

    detailed thermal plant modeling (unit commitment, "take or pay" fuel contracts, concave and convex efficiency curves, fuel consumption constraints, multiple fuels etc.);

    representation of spot markets and supply contracts;

    hydrological uncertainty: it is possible to use stochastic inflow models that represent the system hydrological characteristics (seasonality, time and space dependence, severe droughts etc.) and the effect of specific climatic phenomena such as the El Niño;

    detailed transmission network: Kirchhoff laws, limits on power flows in each circuit, losses, security constraints, export and import limits for electrical areas etc;

    load variation per load level and per bus, with monthly or weekly stages (medium or long term studies) or hourly levels (short term studies).
