Distributed generation, also distributed energy, on-site generation (OSG),or district/decentralized energy, is electrical generation and storage performed by a variety of small, grid-connected or distribution system-connected devices referred to as distributed energy resources (DER). Conventional power stations.
Historically, central plants have been an integral part of the electric grid, in which large generating facilities are specifically located either close to resources or otherwise located far from populated .
For reasons of reliability, distributed generation resources would be interconnected to the same transmission grid as central stations. Various technical and economic issues occur in the integration of these resources into a grid. Technical problems arise.
It is now possible to combine technologies such as ,and to make stand alone distributed generation systems.Recent work has shown that such systems have a low .Many authors now think.
A microgrid is a localized grouping of electricity generation, energy storage, and loads that normally operates connected to a traditional centralized grid (). This single point of common coupling with the macrogrid can be disconnected. The microgrid can then.
