Commelec
Open-knowledge reference entry

Commelec is a framework that provides distributed and real-time control of electrical grids by using explicit setpoints for active/reactive power absorptions/injections. It is based on the joint-operation of communication and electricity systems. Commelec has been developed by scientists at École Polytechnique Fédérale de Lausanne, a research institute and university in Lausanne, Switzerland. The Commelec project is part of the SNSF's National Research Programme “Energy Turnaround” (NRP 70).
Motivation
Due to penetration of a large amount of distributed generation, modern power systems are facing numerous challenges such as the absence of inertia, stochastic power generation, grid stress and stability issues. This could lead to problems related to power balance, power quality, voltage and frequency control, system economics and load dispatch. The conventional distribution grid was not designed to support the distributed generation of electricity. Therefore, Commelec framework is developed in order to guarantee a proper grid operation under these challenges without major grid reinforcements. It can provide both primary frequency control and secondary voltage control, being also capable to operate in islanded mode. In contrast to conventional droop-control, it keeps the equilibrium point without using the frequency as the main indicator of power imbalance.
This brief starts where responsible research should: with the source description of “Commelec” as open-knowledge reference entry. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as open-knowledge reference entry. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Dec 20, 2025. The linked authority identifier is Q96375340. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
- Subject orientation
- Search vocabulary

The closest primary source, responsible institution and strongest cited specialist reference.
Three-step research path
- Establish the record: confirm the title “Commelec”, its source revision and the description used here.
- Expand the search: follow Commelec primary sources, Commelec archive and Commelec research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
