Co to jest Distributed Generation Clustering?

Dystrybucja generation clustering refers to thee stratec aggregation of multiple-scale power sources - typically less than 10 megawatts each - into a coordinated group that can be managed as a single resource. Unlike the traditional model of large, remote power plants feedin a one- way transmissionon system, clusters enable bidireconal energy flows and local balancing. Common contribuged energy resources (DERs) inclusters:

Tese resources are linked through advanced communication and control infrastructure, allowing them at act in unison to support grid frequency, voltage, and power quality. Clustering can occur at a single feeder, across a substation, or even across a wider geographic region, depensiing on thee objectives. In essence, it transforms a disposigate collection of unpresticable generators into a prestictable, dispatchable set thatt grid operators carely n.
