  • Publication number: 20210288499
    Abstract: The invention relates to a method of operating a node of a power distribution system in an optimised manner so as to minimise transmission losses on an external power bus. A power generator feeds in electrical energy via an inverter capable of carrying out Volt/VAR control under the command of an optimiser associated with a supervised learning model such as a support vector machine. This optimisation takes place in two distinct training phases, one in which the supervised learning model is trained, another in which optimal control parameters for the inverter are obtained.
