As electricity is generally used by everybody, as it crosses regional and national borders and is essential to a broad variety of industrial sectors, the development of standards for connecting generators to the grid and electricity-consuming products is very much in the interest of society. Consequently, international standards which can be used in technical specifications, regulations, executive orders and legislation are of considerable interest to Energinet.dk.

In addition to the connection of generators and equipment, the quality of the power generated is extremely important to the stability of the power system, and for this reason Energinet.dk also takes a keen interest in quality standards. Moreover, requirements concerning electrical noise and environmental impacts are important when it comes to connecting various types of equipment to the power system.

As electricity, quite apart from being extremely useful, can also be dangerous, safety standards are, of course, also of interest to Energinet.dk in various contexts.

How are we involved in developing standards?
All standardisation activities take place via Energinet.dk's membership of Danish Standards, which nominates experts to the various international task forces. Organisationally, the international standardisation bodies consist of technical committees (TCxx) within the various fields of expertise. Under the technical committees, the development of standards takes place in working groups and project teams (WGxx or PTxx). Under Danish Standards, a so-called mirror committee (S-xxx) has been set up for each technical committee, and under this working groups called A-xx. Energinet.dk plays an active role on both national and international committees and groups.

Where are we involved in developing standards?
The standardisation bodies on which we serve are concerned with the power system and the facilities and units connected to the power system. The primary international standardisation bodies with which Energinet.dk is involved are:

IEC - International Electrotechnical Commission
IEC prepares, maintains and sells standards applicable to electrical machinery, solar cells, wind turbines, current and voltage levels and quality requirements as regards the power generated as well as the noise emitted and received by electrical apparatus. Energinet.dk is very actively involved with the following IEC working groups and committees:

• IEC Technical Committee 57 - Power systems management and associated information exchange
• TC57 WG10 - IEC 61850 standard series - Power system communication
• TC57 G15 - IEC 62351 standard series - Data and communication security
• IEC Technical Committee 88 - Wind turbines
• TC88 WG27 - Electrical simulation models for wind power generation
• IEC Technical Committee 13 - Electrical energy measurement, tariff and load control

CENELEC - Comité Européen de Normalisation Electrotechnique
CENELEC prepares, maintains and sells European standards applicable to electrical machinery, solar cells, wind turbines, current and voltage levels and quality requirements for the power generated as well as the noise emitted from and received by electrical apparatus. Energinet.dk is an active member of the following CENELEC committee:

• IEC Technical Committee 8 - Systems aspects for electrical energy supply.
