World Energy Projection System Plus Model Documentation 2011: Commercial Model

摘要

The Commercial Model of the World Energy Projection System Plus (WEPS+) is an energy demand modeling system of the world commercial end-use sector at a regional level. This report describes the version of the Commercial Model that was used to produce the commercial sector projections published in the International Energy Outlook 2011 (IEO2011). The Commercial Model is one of 13 components of the WEPS+ system and can also be run as a separate, individual model. The WEPS+ is a modular system, consisting of a number of separate energy models that are communicate and work with each other through an integrated system model. The model components are each developed independently, but are designed with well-defined protocols for system communication and interactivity. The WEPS+ modeling system uses a shared database (the restart file) that allows all the models to communicate with each other when they are run in sequence over a number of iterations. The overall WEPS+ system uses an iterative solution technique that forces convergence of consumption and supply pressures to solve for an equilibrium price.
