ETSI - ES 203 474

Environmental Engineering (EE); Interfacing of renewable energy or distributed power sources to 400 VDC distribution systems powering Information and Communication Technology (ICT) equipment

active, Most Current
Organization: ETSI
Publication Date: 1 March 2018
Status: active
Page Count: 30
scope:

The present document defines interconnection of site power installation feeding up to 400 VDC interface, to site renewable energy or to distributed DC power. The covered aspects are:

• general power architectures for:

- connection of a site renewable energy source (PV, wind generator, fuel cells, etc.) to a site power plant and especially the DC power system, (the site sources being on the buildings or around);

- exchange of power to and from a DC nano or micro grid for use and production out of the site (this includes dedicated remote powering network built for ICT access equipment but also more general purpose DC electric grids);

- conditions required to keep specified performance for the up to 400V power system:

electrical stability;

reliability and maintainability;

proper battery charge and management;

lightning protection coordination;

EMC and transient limits;

- specification of proper power sizing, Requirement for control-monitoring and power metering;

- assessment of performances (AC grid energy saving, reliability, flexibility, environmental impact, etc.).

The present document does not cover:

• renewable energy dimensioning;

• power injection into the legacy AC utilities which is already covered by many standards (e.g. from IEC);

• some of the smart power management possibilities through exchanges with DC nano or micro grid.
