RED ELÉCTRICA DE ESPAÑA MIT PRINCIPAL REQUIREMENTS (I) q Provides telecommunication infrastructure status overview m m q q Provides telecommunications alternatives to automatically mitigate the failure and keeps alive the control loop →Selfhealing network Considers an identifies different levels m q Identifies and communicates failures Application, presentation, transport, network, link, phisical level Addresses various levels of hierarchy m Gathers necessary information from the lower level agents and selected peers m Alert the agents at higher levels based on analisys Should automatically discover the information and abilities available from other agents. MIT requirements from the TSO perspective 8

RED ELÉCTRICA DE ESPAÑA MIT PRINCIPAL REQUIREMENTS (II) q Generates a fast local control actions coordinated by global analysis. q Deals with a distributed system architechture q Modular, flexible, scalable to meet operational needs q Covers different temporal dimensions m q q Ranging from: ms (Protections Reaction), to hours (Market forecast), . . System preferably based on Plug and Play modules, HW and SW based on Standards (IEC 61850, CIM…) Provides situational awareness m The operator should understand the state of the system at a glance m Drill down to the details.
