Detailed transmission network: Kirchhoff laws, power flow limit in each circuit, losses, security constraints, export and import limits for each electrical area etc.
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.Representation of spot markets and supply contracts.Detailed thermal plant modeling (unit commitment, generation constraints due to "take or pay" fuel contracts, concave and convex efficiency curves, fuel consumption constraints, bi-fuel plants etc.).Operational details of hydro plants (water balance, limits on storage and turbined outflow, spillage, filtration etc.).The model calculates the least-cost stochastic operating policy of a hydrothermal system, taking into account the following aspects: SDDP is a hydrothermal dispatch model with representation of the transmission network and used for short, medium and long term operation studies.
