Distributed generation (DG) involves small-scale power generation technologies located near the end-users, which reduces energy loss during transmission and decreases the need for extensive power lines. While DG offers benefits such as enhanced efficiency and reduced carbon emissions, it also faces challenges related to power quality and maintenance costs. Overall, DG plays a critical role in modern electricity generation and enhances grid resilience.

2. Introduction
Distributed generation (DG), also known as on - site generation, distributed
resources (DR), distributed energy resources (DER) or dispersed power
(DP) is the use of small - scale power generation technologies located close
to the load being served

3. Most countries generate electricity in large centralized facilities, such as
fossil fuel (coal, gas powered), nuclear, large solar power plants or
hydropower plants. These plants have excellent economies of scale, but
usually transmit electricity long distances and can negatively affect the
environment.
Introduction

4. Distributed generation reduces the amount of energy lost in the transmission of
electricity because the electricity is generated close to where it is used, and
possibly even in the same building.
This also reduces the size and number of power lines that must be created

9. Benefits of Distributed Generation
No high peak load shortages
Reduced high transmission and distribution losses
Linking remote and inaccessible areas
Faster response to new power demands

10. Disadvantages of Distributed Generation
Power Quality
Cost of Operation and Maintenance
Long term reliability of the units
( Not all the DGs types )

11. Distributed Generation Applications
Continuous Power
Emergency Power System
Standby Power System
Ancillary Service Power

12. Conclusion:
The distributed generation help us to reduce the cost of the transmission line and the
transmission losses.
Distributed generation play an important role in the field of the electricity
generation whereas Different issues related to power quality.
By generating electricity in smaller amounts closer to end-users, we can
dramatically increase energy efficiency, reduce carbon pollution, improve grid
resiliency, and curtail the need for new transmission investments.
