Distributed energy resources, or DER, are small-scale energy systems that power a nearby location. DER can be connected to electric grids or isolated, with energy flowing only to specific sites or functions. DER include both energy generation technologies and energy storage systems.
DERs often always exist on the end-user’s side of the electric meter, although some smaller communities own DERs and use them as a power source. Some examples of distributed energy sources include:
Distributed energy systems are an integral part of the sustainable energy transition. DES avoid/minimize transmission and distribution setup, thus saving on cost and losses. DES can be typically classified into three categories: grid connectivity, application-level, and load type.
Some examples of distributed energy sources include: Distributed energy resources can be physical resources that are owned privately or by electric utilities, or they can be virtual assets composed of many physical DERs aggregated together as a single power source.
Distributed generation is the energy generated near the point of use. The ongoing energy transition is manifested by decarbonization above all. Renewable energy is at the heart of global decarbonization efforts. Distributed energy systems are complimenting the renewable drive.
DG is regarded to be a promising solution for addressing the global energy challenges. DG systems or distributed energy systems (DES) offer several advantages over centralized energy systems.
