Overview
IEC SRD 62913-1:2019 - "Generic smart grid requirements – Part 1" defines a common, systems-based methodology for deriving generic smart grid requirements from Use Cases. Built on the IEC systems approach and the IEC 62559 Use Case methodology, this SRD provides guidance, templates and a UML profile to ensure consistent, homogeneous requirement descriptions across smart grid standardization work.
Key topics
- Use Case methodology applied to smart grids: Detailed guidance on describing Use Cases and extracting functional and non‑functional requirements using the IEC 62559 approach.
- Systems approach: How to apply an IEC systems perspective to smart energy domains, breaking down scope and linking to conceptual models (e.g., SGAM-like views).
- Role and actor harmonization: Principles and governance for naming, harmonizing and managing domain roles/actors to avoid ambiguity across committees.
- Requirements capture levels: Structured levels of detail (business/process → system → technical) for capturing generic smart grid requirements.
- UML modelling: A dedicated UML Use Case profile and recommended diagrams (overview, domain, scenario, activity) for formal modelling and traceability.
- Governance and management: Recommended working principles, Use Case Manager function, and reporting templates to coordinate TC roadmaps and role models.
- Annexes and practical templates: Mappings to IEC 62559 templates, example telecommunication non‑functional requirements, lists of existing actors and conceptual models.
Practical applications
IEC SRD 62913-1 is intended to be a practical toolkit for creating reusable, harmonized smart grid requirements that feed into standards development. Typical uses:
- Creating a consistent repository of smart grid Use Cases and derived requirements for cross‑committee standardization.
- Translating high‑level business processes into system and technical requirements for utilities, vendors and integrators.
- Defining role/actor taxonomies to align terminology across domains (generation, distribution, market, customer).
- Producing UML-based documentation to support interoperability, architecture mapping and requirements traceability.
Who should use this standard
- IEC technical committees and standards developers preparing smart energy standards.
- Systems and solution architects in utilities and grid operators who map business Use Cases to system requirements.
- Vendors and integrators creating interoperable products and interfaces for smart grid environments.
- Policymakers and program managers coordinating smart grid projects requiring aligned requirements and governance.
