SAREF4TESS Ontology Requirements Specification
Käsitlusala: This CWA defines a semantic framework for modelling, integrating, and optimizing Thermal Energy Storage (TES) systems within modern energy ecosystems. It supports data harmonization and semantic interoperability between TES components and energy management systems.
This CWA addresses small to medium-scale TES systems, as applied in building and district-level energy systems. Larger TES installations are outside the main scope, although the semantic framework may be extended in the future. Industrial process heat applications are excluded from the current scope and identified as future work.
NOTE The document provides a state-of-the-art description aligned with the scope of the HYSTORE Horizon Europe project, focusing on the “All-in-One Solution” for latent TES and zeolite-water sorption for TCM TES. This represents a specific initial use case and may not fully cover other PCM and TCM based TES systems. Therefore, the ontology is designed to be extensible, providing future expansion of its abstraction level and domain of application.

Determination of power losses in high-voltage direct current (HVDC) converter stations
Käsitlusala: IEC 61803:2026 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 61803:2026 edition 3.0 and the previous IEC 61803:2020 edition 2.0. Furthermore, comments from IEC SC 22F experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content.
IEC 61803:2026 applies to all high-voltage direct current (HVDC) converter stations with line-commutated converters (LCC) as well with voltage-sourced converters (VSC) used for power exchange (power transmission or back-to-back installation) in utility systems. For line-commutated converters (LCC), this document presumes the use of 12-pulse thyristor converters but can, with due care, also be used for 6-pulse thyristor converters. Where VSC is referred to in this document, it is assumed to be of the MMC-type or similar, with very low harmonic generation. It is important to treat other types of VSC as appropriate. In some applications, synchronous compensators, static var compensators (SVC), or static synchronous compensator (STATCOM) are connected to the AC bus of the HVDC converter station. The loss determination procedures for such equipment are not included in this document. This document presents a set of standard procedures for determining the total losses of an HVDC converter station, except for VSC valves which are covered by the IEC 62751 series. The procedures cover all parts, except as noted above, and address no-load operation and operating losses together with their methods of calculation which use, wherever possible, measured parameters. Converter station designs employing novel components or circuit configurations compared to the typical design assumed in this document, or designs equipped with unusual auxiliary circuits that can affect the losses, are assessed on their own merits.
This edition includes the following significant technical changes with respect to the previous edition:
a) HVDC stations with voltage-sourced converters (VSC) technology have been included;
b) to facilitate the application of this document and to ensure its quality remains consistent, 5.1.8 and 5.8 have been reviewed, taking into consideration that the present thyristor production technology provides considerably less thyristor parameters dispersion comparing with the situation in 1999 when the first edition of IEC 61803 was developed; therefore, the production records of thyristors can be used for the power losses calculation;
c) the calculation of the total station load losses (cases D1 and D2 in Annex C) has been corrected.

IEC 61803:2026
Determination of power losses in high-voltage direct current (HVDC) converter stations
Käsitlusala: IEC 61803:2026 applies to all high-voltage direct current (HVDC) converter stations with line-commutated converters (LCC) as well with voltage-sourced converters (VSC) used for power exchange (power transmission or back-to-back installation) in utility systems. For line-commutated converters (LCC), this document presumes the use of 12-pulse thyristor converters but can, with due care, also be used for 6-pulse thyristor converters. Where VSC is referred to in this document, it is assumed to be of the MMC-type or similar, with very low harmonic generation. It is important to treat other types of VSC as appropriate. In some applications, synchronous compensators, static var compensators (SVC), or static synchronous compensator (STATCOM) are connected to the AC bus of the HVDC converter station. The loss determination procedures for such equipment are not included in this document. This document presents a set of standard procedures for determining the total losses of an HVDC converter station, except for VSC valves which are covered by the IEC 62751 series. The procedures cover all parts, except as noted above, and address no-load operation and operating losses together with their methods of calculation which use, wherever possible, measured parameters. Converter station designs employing novel components or circuit configurations compared to the typical design assumed in this document, or designs equipped with unusual auxiliary circuits that can affect the losses, are assessed on their own merits.
This edition includes the following significant technical changes with respect to the previous edition:
a) HVDC stations with voltage-sourced converters (VSC) technology have been included;
b) to facilitate the application of this document and to ensure its quality remains consistent, 5.1.8 and 5.8 have been reviewed, taking into consideration that the present thyristor production technology provides considerably less thyristor parameters dispersion comparing with the situation in 1999 when the first edition of IEC 61803 was developed; therefore, the production records of thyristors can be used for the power losses calculation;
c) the calculation of the total station load losses (cases D1 and D2 in Annex C) has been corrected.

Determination of power losses in high-voltage direct current (HVDC) converter stations with line-commutated converters
Käsitlusala: IEC 61803:2020 applies to all line-commutated high-voltage direct current (HVDC) converter stations used for power exchange (power transmission or back-to-back installation) in utility systems. This document presumes the use of 12-pulse thyristor converters but can, with due care, also be used for 6-pulse thyristor converters. In some applications, synchronous compensators or static var compensators (SVC) may be connected to the AC bus of the HVDC converter station. The loss determination procedures for such equipment are not included in this document. This document presents a set of standard procedures for determining the total losses of an HVDC converter station. The procedures cover all parts, except as noted above, and address no-load operation and operating losses together with their methods of calculation which use, wherever possible, measured parameters. Converter station designs employing novel components or circuit configurations compared to the typical design assumed in this document, or designs equipped with unusual auxiliary circuits that could affect the losses, are assessed on their own merits. This edition includes the following significant technical changes with respect to the previous edition:
- to facilitate the application of this document and to ensure its quality remains consistent, 5.1.8 and 5.8 have been reviewed, taking into consideration that the present thyristor production technology provides considerably less thyristor parameters dispersion comparing with the situation in 1999 when the first edition of IEC 61803 was developed, and therefore the production records of thyristors can be used for the power losses calculation;
- the calculation of the total station load losses (cases D1 and D2 in Annex C) has been corrected.

Dry, solid insulating materials - Resistance test to high-voltage, low-current arc discharges
Käsitlusala: This International Standard describes a test method which can provide preliminary differentiation between similar insulating materials, with respect to their resistance to damage when exposed to high-voltage, low-current arc discharges, occurring close to their surfaces.
The discharges cause localized thermal and chemical decomposition and erosion and eventually a conductive path forms across the insulating material. The severity of the test conditions is gradually increased: in the early stages a low-current arc discharge is repeatedly interrupted, whereas in the later stages, the arc current is raised in successive steps.
Because of its convenience and because of the short time required for testing, the test method is applicable for preliminary screening of materials, for detecting the effects of changes in formulation and for quality control testing.
Previous experience with this test, showed acceptable reproducibility with thermoset materials.
Using thermoplastics, some testing laboratories report unacceptably large variation in test results which lead to the recommendation not to use the test for thermoplastics.
NOTE Attempts are being made to reduce the variability of the results of tests on thermoplastics by controlling the electrode pressure and depth of penetration into the material during the test. Without such electrode control, tests on many thermoplastics may not be sufficiently meaningful to be performed.
This test method will not, in general, permit conclusions to be drawn concerning the relative arc resistance rankings of materials which may be subjected to other types of arcs.
The ranking of materials may differ from what is found in wet tracking tests (e.g. IEC 60112:2025, IEC 60587:2022 and IEC 61302:1995) and from their performance in service, where the intensity, recurrence frequency and time of exposure to arc discharges are very different.Nevertheless, a certain correlation with the Inclined-Plane-Test according to IEC 60587:2022 was found within one material group (e.g. silicone elastomers).
