Excluded from the scope of this document are:
- methods based on optical or ultrasonic PD detection,
- fields of application for PD measurements when stressed by non-repetitive impulse voltages such as lightning impulse or switching impulses from switchgear.
This edition includes the following significant technical changes with respect to the previous edition:
a) background information on the progress being made in the field of power electronics including the introduction of wide band gap semiconductor devices has been added to the Introduction;
b) voltage impulse generators; the parameter values of the voltage impulse waveform have been modified to reflect application of wide band gap semiconductor devices.

IEC TS 62898-3-2:2024 provides technical requirements for the operation of energy management systems of microgrids. This document applies to utility-interconnected or islanded microgrids. This document describes specific recommendations for low-voltage (LV) and medium-voltage (MV) systems.
This document focuses on developing standards of energy management systems aimed for microgrids integrated in decentralized energy systems or public distribution grids. It concerns some particularities that are not totally covered by the existing conventional energy system. The microgrid energy management systems are being studied by various actors (utilities, manufacturers, and energy providers) on actual demonstration projects and application use case. The aims of this document are to make the state of the art of existing energy management systems used in actual microgrids projects, to classify the relevant functions which can be accomplished by microgrid energy management systems, and to recommend necessary technical requirements for energy management systems of future microgrids.
This document includes the following items:
• main performances of key components of microgrid: decentralized energy resources, energy storages and controllable loads),
• description of main functions and topological blocks of microgrid energy management systems (MEMS),
• specification of information exchange protocol between main function blocks, linked to microgrid monitoring and control systems (MMCS).
Main functions of MEMS:
• power and energy management among different resources within microgrid including active and reactive power flows with different time scales,
• power and energy forecasts of microgrid,
• energy balancing between upstream grid and microgrid energy resources according to power and energy forecast and upstream and local constraints,
• economic and environmental optimization,
• possible service capacities such as capacity market auctions and resiliency anticipation: new business models,
• data archiving, trending, reporting and evaluation of operation capacities in various operation modes.
MEMS can have some other additional functions according to microgrid size and actual application cases:
• tariff and market trading management,
• utility ancillary services such as frequency regulation, voltage regulation, power quality and reliability improvement, demand response possibilities, change of operation modes linked to MMCS.

IEC TS 63191:2023 specifies recommendations about power quality measurement and assessment within installations.
This document outlines the various phases needed for the establishment of a demand-side power quality measurement plan for buildings and industry installations.
Such a power quality measurement plan will enable the optimization of the energy availability and efficiency, improve the assets lifetime and facilitate the resolutions of power quality problems. A power quality measurement plan encompasses the following phases:
• definition of the context, objectives and constraints;
• assessment of the initial power quality situation;
• definition of an action plan for the improvement of the power quality situation;
• implementation of the power quality measuring system;
• exploitation of the measurement system for the improvement of the power quality situation;
• maintenance of the measurement system.
This document will also help facility managers tailor their measurement plan to the specific needs of the electrical system under their control. It addresses all the disturbances present in such networks, but does not cover the disturbances present in public electrical distribution networks (supply side) as they are governed by specific documents such as EN 50160 and IEC TS 62749.
IEC TS 63191:2023 cancels and replaces IEC TR 63191, published in 2018. This edition constitutes a technical revision.

IEC TS 60079-44:2023, which is a Technical Specification, is to provide guidance to establish recommended minimum criteria to determine roles, establish expectations of the necessary skills and evidence of competence to assess and manage the competence of personnel conducting work in or associated with hazardous areas. The purpose of this document is to provide guidance to establish:
• recommended minimum criteria to determine roles,
• expectations of the necessary skills, and
• evidence of competence
in order to assess and manage the competence of personnel who are conducting work in or associated with hazardous areas.
This document provides examples and recommendations of minimum levels of competence for typical roles associated with hazardous areas by addressing the knowledge, skills, or abilities that is expected of personnel. Additionally, examples of the evidence of competence expected for each role are provided.
The aim of tThis document is to assist in defining, assessing, and managing unique requirements for the competence of individuals working in or associated with installations where an explosive atmosphere could be present. Such a programme could be specific to a facility or used in conjunction with other regulatory requirements where they exist.

This document applies to both electrical and non-electrical applications.
This document identifies the minimum level of knowledge and skills required to work in hazardous areas and the specific competence required for work associated with equipment for explosive atmospheres (commonly termed ‘Ex Equipment’) and the standards to which competence is to be assessed and attributed.
The purpose of this document is to provide guidance to establish:
• recommended minimum criteria to determine roles,
• expectations of the necessary skills, and
• evidence of competence
The principal application of this specification document is for personnel dealing with explosion-protected and associated equipment for use in explosive atmospheres, including the following work functions:
• Classification of areas;
• Producing, processing or servicing functions in a hazardous area and not directly involved in installing, maintaining or repairing explosion-protected equipment and systems;
• Designing, commissioning and maintaining explosion-protection strategies and equipment;

IEC TS 62351-100-4:2023, which is a technical specification, describes test procedures for interoperability conformance testing of data and communication security for power system automation and protection systems which implement MMS, IEC 61850-8-1 (MMS), IEC 61850-8-2 (XMPP) or any other protocol implementing IEC 62351-4:2018/AMD1:2020. The tests described in this document cover only E2E security testing and do not evaluate A-security profile implementation. Thus, citing conformance to this document does not imply that any particular security level has been achieved by the corresponding product, or by the system in which it is used.
The goal of this document is to enable interoperability by providing a standard method of testing protocol implementations, but it does not guarantee the full interoperability of devices. It is expected that using this document during testing will minimize the risk of non interoperability. Additional testing and assurance measures will be required to verify that a particular implementation of IEC 62351-4:2018/AMD1:2020 has correctly implemented all the security functions and that they can be assured to be present in the delivered products. This topic is covered in other IEC standards, for example IEC 62443.
The scope of this document is to specify available common procedures and definitions for conformance and/or interoperability testing of IEC 62351-4:2018/AMD1:2020.
This document deals mainly with cyber security conformance testing; therefore, other requirements, such as safety or EMC are not covered. These requirements are covered by other standards (if applicable) and the proof of compliance for these topics is done according to these standards.
T-profile testing is to be performed prior to E2E security profile testing. T-profile testing is described in IEC 62351-100-3 in the context of IEC 61850-8-1. T-profile testing for IEC 61850-8-2 is to be described in the corresponding IEC 61850-8-2 test specification.
