Distributed generation, also distributed energy, on-site generation (OSG), or district/decentralized energy, is electrical and performed by a variety of small, -connected or distribution system-connected devices referred to as distributed energy resources (DER). Conventional, such as -fired,, and plant.
Distributed energy storage is also a means of providing grid or network services which can provide an additional economic benefit from the storage device. Electrical energy storage is shown to be a complementary technology to CHP systems and may also be considered in conjunction with, or as an alternative to, thermal energy storage.
What is distributed energy?
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).
Could a smart grid be a decentralized power storage and generation system?
This trend is rapidly gaining momentum as DG technologies improve, and utilities envision that a salient feature of smart grids could be the massive deployment of decentralized power storage and generation systems, also called distributed energy resources or DERs.
Why is distributed energy storage a key enabler of smart grids?
Distributed energy storage is widely recognized as a key enabler of smart grids for its role in complementing renewable generation by smoothing out power fluctuations [56,57]. For instance, surplus energy can be stored during conditions of low demand and supplied back during periods of heavy load.
What is a distributed energy resource system?
Distributed energy resource (DER) systems are small-scale power generation or storage technologies (typically in the range of 1 kW to 10,000 kW) used to provide an alternative to or an enhancement of the traditional electric power system. DER systems typically are characterized by high initial capital costs per kilowatt.
How does distributed storage affect the grid?
In the case of applying distributed storage to a distributed generation installation, the impacts of distributed generation on the grid may be less; however, there is also lost revenue for the utility, offset by the ability to utilize the asset.
