Microgrids - Part 1: Guidelines for microgrid projects planning and specification
IEC TS 62898-1:2017+AMD1:2023 provides guidelines for microgrid projects planning and specification. Microgrids considered in this document are alternating current (AC) electrical systems with loads and distributed energy resources (DER) at low or medium voltage level. This document does not cover direct current (DC) microgrids. Microgrids are classified into isolated microgrids and non-isolated…
Power losses in voltage sourced converter (VSC) valves for high-voltage direct current (HVDC) system...
IEC 62751-2:2014+AMD1:2019+AMD2:2023 gives the detailed method to be adopted for calculating the power losses in the valves for an HVDC system based on the "modular multi-level converter", where each valve in the converter consists of a number of self-contained, two-terminal controllable voltage sources connected in series. It is applicable both for the cases where each modular cell…
Corrigendum 1 - High-voltage switchgear and controlgear - Part 202: AC prefabricated substations for...
IEC 62271-202:2022 specifies the service conditions, rated characteristics, general structural requirements and test methods of enclosed high-voltage prefabricated substations. These prefabricated substations are cable-connected to AC high-voltage networks with an operating voltage up to and including 52 kV and power frequencies up to and including 60 Hz. They can be manually operated from inside…

IEC TR 61850-90-7:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
IEC TR 61850-90-7:2023, which is a Technical Report, describes functions for power converter-based distributed…
2 SCOPE
This standard applies to any products containing a claimed recycled plastic content of at least 5%, which is either credited according to the Chain of Custody (CoC) mass balance model or actual physical recycled content.
This standard is not intended to determine the mechanical, physical and chemical qualities and properties of a product, nor the adequacy of the product’s constraint…
