the portion of the system that facilities the delivery of electric energy from the transmission system to the end user.
Allows for cost-effective market operation and access to a diverse generation supply, like your rooftop PV system.
Adapting the system to bidirectional energy flows can be expensive and time consuming. Often results in a nontransparent and unbalanced investment for RE developers.
Distribution systems are a pinch point for the development renewable energy distributed energy resources (RE-DER). Efforts to increase RE-DER compatibility, planning and investment are need. Modifications must be balanced against cyber and physical threat potential.
