Changing network conditions and system requirements

CIGRE WG A3.13 is studying the impact of changing network conditions and system requirements on the specification of conventional HV equipment within the scope of SC A3. They see three main developments leading to future networks: the strong increase in distributed generation, the increase in the transmission of bulk power over long distance and the increase in the application of power electronics. The impact of each development is described, conclusions are given or studies going on are highlighted.
