# Stochastic Energy Deployment System (SEDS)

The Stochastic Energy Deployment System (SEDS) model is a capacity-expansion model of the U.S. energy market. The model uses five-year time periods from 2005 to 2050. SEDS can be operated either deterministically or stochastically. When operated deterministically, SEDS uses a single value instead of the input-probability distributions for the uncertain parameters. In this mode, the results are immediate and informative, in terms of how the model responds to different inputs and assumptions. When operated stochastically, SEDS uses Monte Carlo simulations to make a number of sweeps through the time period. In each sweep, the random variables are sampled using a Latin Hypercube approach that improves on a standard Monte Carlo simulation. SEDS is being developed with a commercially available software package, Analytica, designed to facilitate the development of stochastic models (for more information on Analytica, visit Lumina^{[1]}). Contact James Milford of the Strategic Energy Analysis Center (SEAC) for more information.
