IEC publishes Part 221 on load shedding

The International Electrotechnical Commission (IEC) has published Part 221 of IEC 62386, the international DALI standard.

IEC 62386-221:2018 is one a series of Parts that describes particular requirements for control gear, and  defines the requirements for demand response by way of load shedding.

According to the IEC website, Part 221 “specifies the methodology of demand response which focuses on the curtailment of electric loads during peak demand times, thus avoiding the requirement to find new sources of generation capacity. By using load shedding, the lighting system responds to the demands of the energy supply.”

Part 221 applies to control gear supporting the demand response functionality.

Several new Parts of IEC 62386 have been published in the last several months. An up-to-date overview of the standard is available on the DiiA website.
