IEC 62351 - Power Systems Communication Security 12:5: Part 12, clause 5: DER architectures and cyber-physical concepts (the resiliency challenge, the five-level DER hierarchy, DER interfaces, resilience per level, protecting cyber-physical DER, cyber-physical threats and resilience measures)

Resilience is analysed on the five-level DER hierarchical architecture set against the Smart Grid Architecture Model (autonomous DER at customer and utility sites; facility DER energy management; third-party aggregators and retail energy providers; distribution operations; transmission and market), with the interfaces between levels, what resilience means at each level, and DER treated as cyber-physical systems whose protection, threats and resilience measures combine engineering strategies with cyber security techniques.
