An Overview of Distributed Generation Integration Techniques, Present Trends and Future Scope

Distributed generation integration is a new booming and fast-adopting technology. The small rating components, compactness, local power demand fulfilment and renewable-based input energy sources are the attractive features of distributed energy resources. They offer a reliable and secure supply at distribution level. The system as a whole is relieved from heavy power congestion with the presence of these local energy sources. However, DERs suffer from low inertia issues, power quality problems and changing input energy and load patterns. This paper reviews the DG technologies in service, their contribution in total energy demands and need for active distribution networks and future challenges.
