Distribution grids
are growing increasingly complex and dynamic as utilities
work to meet renewable energy portfolio standards, improve
operational efficiencies and facilitate the connection
of electric vehicles.
Smart switches need to support new
functionalities, such as load balancing and peak shaving and
must meet a whole new set of requirements, including more
frequent operations.
