Welcome Back

Hello there!

Welcome to GridEdge Intelligence! We're excited to have you join our community and look forward to your involvement.

Our goal is to help you accelerate selection, adoption and implementation of standard communications protocols for grid edge resource integration into grid operations.

Here's What's Inside

What is an Application Protocol?

An Application Protocol communicates information and commands between the Distribution Utility Operator and DERs such as:
‍
  • Configuration
  • Nameplate ratings/device capabilities
  • Security credentials
  • Events
  • Requests – e.g., load reduction
  • Event Optin or Optout
  • Settings of devices
  • Status of devices
  • Commands
  • Meter reads
  • Program enrollment
  • Group settings/management
The initial focus of GEI is on the leading application-level protocols for the grid edge: DNP3, IEC 61850, IEEE 2030.5, IEEE 1547/UL 1741, OpenADR, SunSpec Modbus – as opposed to the transport layer protocols (Wi-Fi, Zigbee, Wi-SUN, etc.).
Note: an application protocol could be sent over any communications network that supports the protocol – wireless, cable, satellite, RF, Fiber optic, etc.
