IEC TR 63043(E), which is a technical report, describes common practices and state of the art for renewable energy power forecasting technology, including general data demands, renewable energy power forecasting methods and forecasting error evaluation. For the purposes of this document, renewable energy refers to variable renewable energy, which mainly comprises wind power and photovoltaic (PV) power – these are the focus of the document. Other variable renewable energies, like concentrating solar power, wave power and tidal power, etc., are not presented in this document, since their capacity is small, while hydro power forecasting is a significantly different field, and so not covered here.
The objects of renewable energy power forecasting can be wind turbines, or a wind farm, or a region with lots of wind farms (respectively PV systems, PV power stations and regions with high PV penetration). This document focuses on providing technical guidance concerning forecasting technologies of multiple spatial and temporal scales, probabilistic forecasting, and ramp event forecasting for wind power and PV power.
This document outlines the basic aspects of renewable energy power forecasting technology. This is the first IEC document related to renewable energy power forecasting. The contents of this document will find an application in the following potential areas:
• support the development and future research for renewable energy power forecasting technology, by showing current state of the art;
• evaluation of the forecasting performance during the design and operation of renewable energy power forecasting system;
• provide information for benchmarking renewable forecasting technologies, including methods used, data required and evaluation techniques -

IEC TR 63037:2019 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 63037:2019 provides guidance to controlgear/integrated lamp designers for the development of products suitable to operate with future phase-cut dimmers. It describes the possible voltage signals and the expected response of the controlgear/integrated lamps. This document describes the expected response of controlgear during all operation states of a phase-cut lighting system and provides a complete understanding of the requirements for phase-cut dimmers. The response of a phase-cut dimmer is described in IEC 60669-2‑1:—, Annex EE. This document specifies the system performance aspects and test procedures for the control by mains voltage phase-cut dimming of the brightness of mains operated electronic lighting equipment intended to be controlled by mains voltage phase-cut dimmers, such as LED integrated lamps and light sources with external controlgear. Safety requirements are not covered by this document, but by respective product standards. This second edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- emission of audible noise;
- ghosting caused by issues that are not related to the power supply of the dimmer or synchronization;
- stability of phase angle waveform (for the dimmer), including symmetry and stability tests;
- flicker of light loads;
- repetitive ring up voltage;
- dimming range; and
- number of switching cycles have been added.Technology -

IEC TR 63036:2016(E) specifies the electrical interface and test procedures for the control by mains voltage phase-cut dimming of the brightness of mains operated electronic lighting equipment intended to be controlled by mains voltage phase-cut dimmers, such as LED integrated lamps, and light sources with external control gear. Electronic switches that use a comparable circuitry to a phase-cut dimmer but do not contain means for the adjustability of the phase-cut angle should fulfill the same requirements as a phase-cut dimmer. Safety requirements are not covered by this document, but by respective product standards.

IEC TR 62978:2017(E) gives guidelines on the current asset management perspectives for HVDC installations based on best practices of asset owners, operators, users, original equipment manufacturers and regulators within the power industry. This document covers HVDC systems with Line-Commutated Converters (LCC) and can be generally applied to Voltage Sourced Converters (VSC), not including specific equipment or sub-equipment required under VSC. This document provides base guidelines on fundamental aspects and prudent practices to be considered by stake holders in managing HVDC assets. Compliance to additional requirements and recommendations stipulated in this document by the supplier or OEM are non-obligatory, unless explicitly specified by the customer.
