Modeling distributed generation in the buildings sectors.

摘要

Distributed and dispersed generation technologies generate electricity near the particular load they are intended to serve, such as a residential home or commercial building. EIA defines distributed generation (DG) as being connected to the electrical grid and intended to directly offset retail sales, and dispersed generation as being off-grid and often used for remote applications where grid-connected electricity is cost-prohibitive. Dispersed generation1 One form of DG is combined heat and power (CHP), which reuses waste heat from on-site generation for purposes such as space heating and water heating. Such technologies are typically used in both commercial and industrial sectors. The following information focuses on how EIA models DG, including CHP, in the residential and commercial sectors. in the buildings sector is not currently gathered by EIA electricity surveys or modeled in the National Energy Modeling System (NEMS), largely because of the difficulty in tracking installations and consumption.
