• Grid Interconnection of Embedded Generation Part 2: Small-Scale Embedded Generation Section 3: Simplified Utility Connection Criteria for Low-Voltage Connected Generators

    NRS097-2-3 (2023): This specification clarifies conditions under which small scale embedded generators (<1MW) may connect to distribution feeders without negative network impact, and thus not require impact studies. Application of the specification speeds up connection approvals significantly (NRS Association).

  • VDE 4105 (2011) Power Generation Systems Connected to the low voltage distribution network

    (SAMPLE) VDE -AR-N 4105 (2011) – Technical minimum requirements for the connection to and parallel operation with low-voltage distribution networks. German standard summarising essential aspects to be taken in to account to ensure safe and reliable network operation.

     

  • IEEE 1547-2018 (Highlights)

    (Powerpoint) Provides an overview of the IEEE 1547-2018 Standard.

    This standard:

    Specifies functional requirements for all Distributed Energy Resources (DERs) connected to typical primary or secondary distribution voltage levels.  It applies regardless of type and size—synchronous, induction, and inverter-based resources of any size.

    Gives precedence to synchronous generator design standards for DERs with synchronous generator units rated 10 MVA and greater.

    Does not apply to resources directly connected to the bulk power system.

  • Engineering Recommendation G83

    Recommendations for the Connection of Type Tested Small-scale Embedded Generators (Up to 16A per Phase) in Parallel with Low-Voltage Distribution Systems.

    The purpose of this Engineering Recommendation is to simplify and standardise the technical requirements for connection of Small Scale Embedded Generators (SSEGs) for operation in parallel with a public low-voltage Distribution System, by addressing all technical aspects of the connection process from standards of functionality to site commissioning (Energy Networks Association).
