IntroductionStrategy and DirectionMembership and ExpertsWorking AreasWorking GroupsPublicationsTutorialsPreferential SubjectsEventsConclusionsSubstations play a key role as nodes within electrical networks, providing the capability for the network to deliver safe, reliable energy with high availability. To support the realisation of a sustainable society, substations’ research & development continues to make advances in new technologies and applications that offer substation owners and operators the flexibility, security and stability they need to continue to expand their systems in an efficient and environmentally friendly manner. However, transmission substations remain essential for bulk power transmission such as interconnecting load regions, large generation resources and energy storage, and offshore supplies. The focus area for SC B3 is the coordinated design and operation between transmission and distribution, to facilitate more flexible and active distribution networks.
