2 What is CIGRE ?Founded in 1921, CIGRE , the Council on Large Electric Systems, is aninternational Non-profit Association for promoting collaboration withexpertsfromaroundtheworldbysharingkn owledgeandjoiningexpertsfromaroundthewor ldbysharingknowledgeandjoiningforces to improve electric power systems of today and tomorrow. Performstudiesontopicalissuesoftheelectr icpowersystem Performstudiesontopicalissuesoftheelectr icpowersystem,such as Supergrid, Microgrid and lifetime management of aged assets,anddisseminate new technologyand improve energy efficiency. Review the state-of-the-art of technical specifications for powersystems & Equipment and provide technical background based on thecollected information for IEC toassist international standardizations.
