What is PD IEC/TR 62351-12- Distributed energy resources (DER) cyber-physical systems about?
PD IEC/TR 62351-12 is a safety standard on power systems management and associated information exchange.
PD IEC/TR 62351-12 which is a technical report, discusses cyber security recommendations and engineering/operational strategies for improving the resilience of power systems with interconnected Distributed Energy Resources (DER) systems. PD IEC/TR 62351-12 covers the resilience requirements for the many different stakeholders of this dispersed cyber-physical generation and storage devices, with the goal of enhancing the safety, reliability, power quality, and other operational aspects of power systems, particularly those with high penetrations of DER systems.
The focus of PD IEC/TR 62351-12 is describing the impact of DER systems on power system resilience and PD IEC/TR 62351-12 covers the cyber security and engineering strategies for improving power system resilience with high penetrations of DER systems. PD IEC/TR 62351-12 discusses the resilience issues for cyber-physical DER systems interconnected with the power grid, building on the concepts and the hierarchical architecture.
Note: While recognizing that many other requirements exist for improving power system resilience, PD IEC/TR 62351-12 does not address general power system configurations, operations, manual power restoration activities, or the many other non-DER-specific issues.
Who is PD IEC/TR 62351-12- Distributed energy resources (DER) cyber-physical systems for?
PD IEC/TR 62351-12 on data and communications security is relevant to:
- Stakeholders involved in the design, implementation, and operation of DER systems
- Manufacturers, integrator/installers of DER systems
- Information and communication technology (ICT) providers
- Security managers
- Testing and maintenance personnel
- Utility regulators
Why should you use PD IEC/TR 62351-12- Distributed energy resources (DER) cyber-physical systems?
In the energy sector, two key phrases are becoming the focus of international and national policies: “grid resilience” and “cyber security of the cyber-physical grid.” Grid resilience responds to the overarching concern.
Agri-resilience includes grid hardening, advanced capabilities, and recovery/recon Despite the focus on hardening, resilience strategies must also consider ways to improve grid flexibility and control. The ability of the cyber-physical grid to withstand and recover from malicious and accidental cyber events is often associated with grid resilience. Resilience is the ability to quickly recover and continue operations after a disruption. Unintentional attacks and failures can be detected and analysed quickly by a resilient power system. The “cyber-physical grid” implies that the power system is made up of both cyber and physical assets. PD IEC/TR 62351-12 states that distributed energy resources (DER) systems are cyber-physical systems that are increasingly being interconnected to the distribution power system to provide energy and ancillary services. However, distribution power systems were not originally designed to handle these dispersed sources of generation, while DER systems are not under direct utility management or under the security policies and procedures of the utilities. Many DER systems provide energy from renewable sources.
Overall, PD IEC/TR 62351-12 is helpful as it assists the user with cyber-physical systems, i.e., engineered systems that are built from and depend upon the cooperation of computational and physical components.
