IEEE 1547.3-2023

IEEE 1547.3-2023 is a technical guide for cybersecurity of distributed energy resources interconnected with electric power systems. It is aimed at helping organizations address cyber-related considerations for interconnected equipment and supporting systems, where communications, controls, and power interface functions may affect reliable operation. IEEE 1547.3-2023 matters because cybersecurity concerns can influence equipment integration, operational integrity, and coordination across connected energy resources and power-system interfaces.

IEEE 1547.3-2023 overview

This standard focuses on the cybersecurity context surrounding distributed energy resources and their connection to electric power systems. It is best understood as a guide rather than a device specification, offering technical direction for evaluating and organizing security-related concerns in interconnected environments. The document is relevant to systems where power conversion, monitoring, control, and communications meet at the point of interconnection. For users comparing standards, IEEE 1547.3-2023 helps define a clearer technical framework for secure integration and operational consistency.

Typical use cases

IEEE 1547.3-2023 is commonly consulted when planning or reviewing cybersecurity considerations for inverter-based generation, storage systems, and other distributed energy resources linked to utility or facility power networks. It may support engineering teams, integrators, and operators working on interconnection design, system control, remote communications, and equipment coordination. The guide is also useful during procurement and specification review when cybersecurity expectations for connected energy equipment need to be aligned with the broader electric power system environment.

Why this standard matters

Cybersecurity is increasingly important wherever distributed energy resources interact with electric power systems, since connected controls and communications can introduce operational risk if not addressed consistently. IEEE 1547.3-2023 helps support more disciplined design decisions, clearer compliance discussions, and better coordination between electrical and information-security requirements. Using this guide can reduce ambiguity during testing, integration, and acceptance activities, while also helping teams compare solutions on a more consistent technical basis. IEEE 1547.3-2023 is therefore useful for managing risk in interconnected energy applications.
