Examples of DERs include rooftop solar systems, battery storage systems, generators, electric vehicles, and demand-side management programs. DERs can be technologies that generate and store power but can also be technologies or operator functions that manage how much and what kind. . 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. . Distributed generation, also distributed energy, on-site generation (OSG), [1] 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). These small-scale, decentralized energy systems help increase grid resilience, lower energy costs, and promote the adoption of renewable energy.
