The document will be based on IEC TS 62898-3-3 (Self-regulation of dispatchable loads), but modified according to the needs of the European framework, e.g. revision of the scope, alignment to the EN 50549 family of standards, including the enhancement of the testing chapter according to EN 50549-10 (in a possibly separate document), and so forth. This technical specification deals with frequency and voltage stabilization of AC electricity networks by dispatchable loads, which react autonomously on variations of frequency and voltage with a change in active power consumption. This document gives requirements to emulate the self-regulation effect of loads including synthetic inertia.
The loads recommended for this approach are noncritical loads, this means their power modulation will not significantly affect the user as some kind of intrinsic energy storage, e.g. electrical, thermal, mechanical either before or after the electrical energy to-end use conversion, or if large time constants are involved. Both options effectively decouple the end energy use from the electricity supply by the electric network. The self-regulation of loads is beneficial both in interconnected operation as well as during emergencies in island mode.
This document gives the details of the self-regulation behaviour but does not stipulate which loads shall participate in this approach as an optional function. This document is a voluntary quality standard.
This document covers continuously controllable loads with droop control and ON/OFF -switchable loads with staged settings. Both strategies may either be applied at the level of individual units (load devices) or at the level of installations, meaning clusters of load units that act as a single controllable entity. The scope of this document is limited to loads connected to nominal voltage levels up to 35 kV. Only 50 Hz electric power systems are covered. Reactive power for voltage stabilisation and DC microgrids are excluded in this document.
