AA1 covers the whole substation in a system approach as node of optimal power system.
. Development of new concepts including novel bus arrangements, mixed substations (hybrid) solutions, applications and functions.
. Considering technical, environmental and economical leading to total optimisation of electric power systems seen as the linkage between generators and consumers including impact of distributed generation, merging of transmission and distribution systems.
. Utilising new technologies and experience, e.g. more compact and multi-functional substations, sophisticated electronic equipment, FACTS, superconductivity etc., to get more overall efficient substation solutions.
