Understanding IEEE 1547-2018 – Interconnection Standard for DER on Distribution
About this course
This course is approved for IEEE 1.0 CEUs/ 10 PDHs as well as NABCEP CEUs.
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.
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.

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.

Voltage/Reactive Power and Response to Abnormal Operating Conditions
In this module we first cover how distribution system operators (referred to as Area EPS Operators in the standard) control voltage and reactive power on the distribution system. We discuss the impacts that DER can have on voltage and reactive power, and how IEEE 1547 requires new installation of DER to have the capability to control voltage and reactive power.
We cover the two Normal Operating Performance Categories (A & B) that the standard has defined for voltage/reactive power capabilities, and we discuss the different voltage control capabilities, particularly provided by smart inverters.
In the second half of this module, we look at the required response of DER to distribution events, and we look at how higher penetrations of DER such as Solar PV have contributed to abnormal events on the Bulk Power System in the US. We also look at the three Abnormal Operating Performance Categories (I, II, & III) that the standards have defined for DER, and look at key DER concepts such as voltage and frequency ride-through, cease-to-energize, momentary cessation, and frequency-droop.

In this module, we go through Clauses 6 - 10 of IEEE 1547-2018. In power quality, we look at requirements specifying the limitation of DC injection, voltage fluctuations induced by DER, current distortion, and overvoltage contribution. We look at unintentional islanding and intentional islanding requirements in the standard, before getting into the installation of DER on secondary networks.
