Distributed Energy Resources (DERs)

open access: yes, 2023
Distributed Energy Resources (DERs) are small-scale electricity generation and storage devices that are connected to the electric grid or operate independently from it. They can include renewable energy sources such as solar panels, wind turbines, biogas, and batteries, as well as controllable loads such as electric vehicles, smart thermostats, and ...
