A regulation process of an electrical distribution network that comprises a main power source, among one or more electrical sources, configured to impose on the network the voltage and frequency of a power circulating on the network to which one or more loads are connected. The process includes, in the event of a variation of one of the frequency or the voltage detected on the network, during a primary regulation, one adjustment step by the main source of the other between the frequency and the voltage, to maintain constant the ratio voltage/frequency.

Regulation process of an electrical distribution network

The invention relates to a method of stabilization between a high frequency and a low frequency, of an electrical network supplying several sub-networks (), each sub-network comprising a sub-network manager () and supplying N consumer sites (), each site, j, comprising sheddable loads (), the method comprising for each sub-network the following steps: ensuring a communication between each site and the sub-network manager thereof; periodically measuring the value of the sheddable power in consumed at each site; deducing for each site an estimated sheddable power; and dispatching to each site j () a threshold frequency, such that sheddable loads () of this site are unplugged when the frequency of the network drops below the threshold frequency, in which the sub-network manager () calculates the threshold frequencies in such a way that the variation of the sheddable powers as a function of frequency is substantially linear.
