Abstract
A method and system are provided for a distributed communications and control network that manages Distributed Energy Resources (“DER”) on a power utility grid. An integrated network and system uses a hub and spoke, substation-centric network architecture, and comprises: a plurality of edge DER (“E-DERM”) devices, each E-DERM device located at a DER point of interconnection; a single substation DER controller (“D-DERM”) located at a utility substation and configured to manage the plurality of E-DERM devices; integrated point-to-point secured communications between the D-DERM and each of the plurality of E-DERM devices using dual-channel, redundant paths; and closed-loop control software algorithms running autonomously on the D-DERM at the utility substation to monitor and control DER connected to power lines emanating from the utility substation.
