Microgrids focus on localized energy independence and resilience, while VPPs manage distributed resources to optimize grid-wide energy supply and demand. . The two terms sound similar, but they are not the same. What is Distributed Generation (DG)? Distributed Generation (DG) refers to small, decentralized power sources located close to where the energy is used. Examples include rooftop solar, small wind turbines, natural gas. . The concepts of distributed energy and microgrids are based on that notion- that it is better when energy is generated and managed closer to point of use. They improve reliability, integrate renewables, and reduce dependence on the main grid. DER produce and supply electricity on a small scale and are spread out over a wide area.
