Cybersecurity of Distributed Energy and Inverter-Based Resources
Scope Overview
- This standard covers the cybersecurity evaluation of network-connected, software-operated endpoint devices that manage significant energy flows and collectively pose a risk to grid stability, such as Distributed Energy Resources (DERs), Inverter-Based Resources (IBR), smart inverters, monitoring devices, control devices, and electric vehicle supply equipment (ESVE) .
- It specifies minimum basic and advanced cybersecurity requirements but does not include methods for validating these requirements, functional testing, or system-level testing .
Key Benefits
- Helps manufacturers ensure their energy management devices meet essential cybersecurity requirements.
- Supports grid stability by addressing aggregated cybersecurity risks from distributed energy and inverter-based resources.
- Allows flexibility in technology implementation, as the standard does not prescribe specific solutions.
