Understanding IEEE 1547-2018 – Interconnection Standard for DER on Distribution

by Tim Taylor • Last updated 02/2023

Course description

It is anticipated that this course will be approved for NABCEP CEUs once it launches at the end of February 2023.

The time has arrived to become knowledgeable about IEEE 1547-2018.

In 2023, it is expected that many families/models of smart inverters will be certified by testing laboratories in accordance with UL 1741 SB, the test procedures for IEEE 1547-2018, and will become commercially available. In addition, more states or other authorities which govern interconnection requirements will have either completed the integration of IEEE 1547-2018 into their interconnection rules and agreements or made additional progress in that area.

Scope of Course
This is a technical course, which assumes you have some understanding of distributed energy resources (DER), particularly inverter-based resources (IBR), and utility distribution systems and engineering.

In this four-module course, you get detailed discussion and reference material on IEEE 1547-2018. We cover the background and need for the different requirements, present default and allowable ranges of inverter settings, and discuss how utilities have been integrating the requirements into their interconnection procedures and specifications.

  • Background and context for the creation and approval of IEEE 1547-2018 - IEEE Standard for Interconnection and Interoperability of Distributed Energy Resources with Associated Electric Power Systems Interfaces
  • General interconnection technical specification and performance requirements
  • Reactive power capability and voltage/power control requirements
  • Response to Area EPS abnormal conditions
  • Power quality
  • Islanding
  • DER on distribution secondary grid/area/street (grid) networks and spot networks Interoperability, information exchange, information models, and protocols
  • An overview of IEEE 1547.1-2020 IEEE Standard Conformance Test Procedures for Equipment Interconnecting Distributed Energy Resources with Electric Power Systems and Associated Interfaces
  • A discussion of IEEE 1547.9-2022 IEEE Guide for Using IEEE Std 1547™ for Interconnection of Energy Storage Distributed Energy Resources with Electric Power Systems

What You Get

  • Copy of all course slides
  • Links to online reference materials
  • Access to all video lectures for one year after course
  • Online interaction with course instructor Tim Taylor during the course
  • One downloadable copy of IEEE 1547-2018 (additional fee of $65)
  • NABCEP CEUs (anticipated once course is completely developed)

Who Should Take This Course

  • DER developers, operators, and aggregators
  • DER system engineers, consultants, and EPC’s
  • Utility distribution management, engineers and subject matter experts involved in DER interconnections
  • DER equipment vendors
  • Bulk power system operators and regional reliability coordinators with interest in distribution DERs and their impacts on bulk power systems

Pre-Requisites
The course is technically-oriented with a focus on the connection of inverter-based DER, such as solar PV, to utility distribution systems. It is recommended that attendees have a background in the electric operation of distribution systems and a basic understanding of inverter operation.

Students should have access to a copy of the actual standard, which we can procure for an additional fee of $65.

Why Take This Course
Higher demand for individuals with a working knowledge of IEEE 1547-2018 will occur as higher penetrations of DER are interconnected to distribution systems. The Inflation Reduction Act (IRA) of 2022 means that the amount of new utility-scale solar PV is forecast to increase dramatically. The IEEE 1547-2018 requirements being adopted will enable more DER connections while maintaining safe and reliable distribution system operation, balanced with secure and reliable operation of the bulk power system.
Individuals and companies will need to know IEEE 1547-2018 to facilitate interconnection to utility distribution over the coming decade. They will need to know what constrains the application of DER to utility feeders, what it means for inverters to be certified with the new UL 1741 SB that is the companion to IEEE 1547-2018, and what are the default settings and ranges of allowable settings of inverters specified in 1547-2018.

In this course, Tim Taylor, Owner of Electric Distribution Academy, brings his 30+ years of experience in utility distribution systems, utility-scale solar plants, and interconnection requirements to give students the background to succeed in the growing utility-scale solar PV industry.

Tim is readily available through the class discussion board and holds periodic office hours.
