What is Distributed Generation

Distributed generation uses decentralized small, modular power technologies to generate energy (electricity and heat) at or close to the point of demand.

It is an approach that employs small-scale technologies to produce electricity close to the end users of power.

Electrical generation and storage performed by a variety of small, grid-connected devices referred to as distributed energy resources.

Electrical generation and storage performed by a variety of small, grid-connected devices referred to as distributed energy resources.

Production of energy from renewable energy sources at different geographical places. The production of energy is not as large as that of conventional power generation that makes up the conventional grid network.

Distributed generation also known as distributed energy or on-site generation can be defined as power generation near to the point of consumer load.

It is an approach that employs small-scale technologies to produce electricity close to the end users of power.

Distributed generation is defined as a small scale power generating unit which is located at nearer to the loads ( Waseem, Pipattanasomporn & Rahman, 2009 ).

Decentralized generation of electricity, involving small-scale power generation systems located at the site of consumption, often allowing the consumer to act as a producer of electricity within the power supply system.

Distributed generation (DG) is also called as dispersed generation or dispersed power generation or de-regulated power generation or distributed power resources or small to medium scale power generation, which is installed near to consumer loads. DG is a small source which may be electric power generation or storage ranging typically from less than few kW to 10 of MW that is not part of the central power source and is connected close to load. Power generating unit which is connected to a distribution network that produces power and supply locally within the network. DG refers to a system that generates electricity (and possibly heat), generally takes place close to the point where energy is actually used. IEEE defines the generation of electricity by facilities that are smaller than central generating plants so as to allow to interconnect at nearly any point in a power system.

Distributed Generation (DG) is a new trend in electric power generation. The basic concept sees an electricity “consumer”, who is generating electricity for his/her own needs, to send surplus electrical power back into the power grid. An example of DG are factories, offices and especially hospitals which require extremely reliable sources of electricity and heating for air conditioning and hot water. To safeguard their supply and reduce costs, some have installed cogeneration or CHP facilities, often using waste material, such as wood waste, or surplus heat from an industrial process to generate electricity. In some cases electricity is generated from a locally supplied fuel such as natural gas or diesel oil and the waste heat from the generator’s thermal energy source is then used to provide hot water and industrial heating as well. It is often economic to have a co-generation plant when an industrial process requires large amounts of heat that are generated from non-electric sources such as fossil fuels or biomass.

It is done from renewable energy resources and cogeneration. Distributed generation (DG) is generally less than 10MW in size, interconnected with distribution feeder, substation and at consumer level.
