The same feature makes it possible to evaluate infrastructure needs for electrical grid and gas transportation facilities. Intertemporal equations to permit examination of retrofitting and life extensions options. An uncertainty index to allow for stochastic and fuzzy logic. We think it will promote the consolidation and uniting of the E 3 optimization community. Commodities are defined as the energy carriers, energy demands, materials, money, and emissions, that flow through the RES network.
Processes are the means of transforming commodities from one form to another.
A process is described by its capacity and activity, with the units of each explicitly defined by the user. Data are organized by attributes that are either global to the model or provide knowledge of the nature of a piece, or time-series, of information to be associated with a process or commodity. An attribute qualifier , or index, provides further knowledge of the specific nature or particular instance of an attribute. Vintaging In traditional systems engineering models, attributes usually have one time index, and the data generally relate to one specific future year. However, the technical characteristics of an installation often change with aging.
