BS PD IEC/TR 62351-12:2016, which is a technical report, discusses cyber securityrecommendations and engineering/operational strategies for improving the resilience of powersystems with interconnected Distributed Energy Resources (DER) systems. It covers theresilience requirements for the many different stakeholders of these dispersed cyber-physicalgeneration and storage devices, with the goal of enhancing the safety, reliability, powerquality, and other operational aspects of power systems, particularly those with highpenetrations of DER systems.The focus of this technical report is describing the impact of DER systems on power systemresilience, and covers the cyber security and engineering strategies for improving powersystem resilience with high penetrations of DER systems.While recognizing that many other requirements exist for improving power system resilience,this technical report does not address general power system configurations, operations,manual power restoration activities or the many other non-DER-specific issues. For instance,power system reliability relies on well-coordinated protective relays, stable power systemdesigns, and well-trained field crews, while control center cyber security relies on many bestpractices for communication network design and firewalls. However, this technical report onlyaddresses the additional reliability and resilience issues caused by 3rd-party managed DERsystems which may not be as well-secured or operated with the same reliability as the utilitymanagedpower system.This technical report discusses the resilience issues for cyber-physical DER systemsinterconnected with the power grid, building on the concepts and the hierarchical architecturedescribed in the Smart Grid Interoperability Panel (SGIP) draft DRGS Subgroup B WhitePaper - Categorizing Use Cases in Hierarchical DER Systems 01-14-2014.docx².Cross References:IEC 62351-9IEC 62443-3-3NIST Special Publication (SP) 800-30 NISTIR 7628:2010IEC 61850-7-420IEC TR 61850-90-7
