  • Patent number: 11057269
    Abstract: Method and system arranged for configuring Intelligent Electronic Device, IED, process bus network switches from a substation specification according to IEC 61850 standard, said method comprising: calculating, from a substation topology file and from control function and substation bay library files, a Substation Specification Description file and substation traffic demand flow files comprising a GOOSE message profile subscription file and a Sampled Values message profile subscription file; generating destination MAC addresses; simulating the process bus communication network using said substation traffic demand flow files and process bus communication network topology, said topology comprising said process bus network switches, respective links and IED links; calculating the shortest path between each publisher IED and each subscriber IED; calculating a switch multicast filtering rule file, for each switch output port, comprising a multicast filter rule that allows the calculated shortest paths; translating

  • Patent number: 10819119
    Abstract: A method for wind power curtailment optimization comprises calculating the power flow for a power network for the day-ahead; calculating a contingency analysis for the power network for the day-ahead, comprising forecasted power generation, power consumption and topology of said power network, together with a set of contingency scenarios; calculating a sensitivity factor of a power flow for each power network branch to a power injection by each wind power plant, wherein the sensitivity factor is calculated only for the periods of time of the day-ahead for which overloaded branches have been detected during the solving of the power flow or during the solving of the contingency analysis; selecting a subset of the wind power plants having at least one sensitivity factor above a predetermined threshold as curtailment candidates; and calculating the wind power curtailment restricted to the selected subset of wind power plants.
