1. A method of controlling an electrical transmission network, wherein the transmission network comprises a plurality of high-voltage DC lines and n AC/DC converters identified by a respective index, with n being greater than or equal to 3, said converters being interconnected by said high-voltage DC lines, each of said AC/DC converters being connected on the one hand to an AC voltage bus identified by a respective index and on the other hand to one of said high-voltage DC lines, the method comprising:
each of the converters of index i applies a power setpoint Pdci with

j being an index designating any AC voltage bus and any converter connected thereto among the number n and different from the AC voltage bus of index i and from said converter connected thereto, Pconxij being a power reference exchanged between the bus of index i and the bus of index j via the electrical transmission network, with n the number of said converters connected to said AC voltage buses;
each converter of index i storing for each of said other converters, the maximum power reference sent
pConxijMax where i≠j
sent from bus i to bus j via the electrical transmission network;
each converter of index i storing for each of the other converters, the maximum power reference received
pConxijmin where i≠j
received by bus i from bus j via the electrical transmission network;
each converter of index i defining the power reference Pconxij so that it observes the stored values of maximum power sent and maximum power received.
