Future households' requirements for demand-side management are auto demand response (AutoDR) function and full control over distributed power sources. Existing solutions feature a direct link between power meters and appliances. A new concept called Smart Distribution Box (SmartDB) provides complete energy and power management solution. It represents an intermediate layer, extending smart grid power meter functionality to support AutoDR with fast and guaranteed response times, distributed power sources, and full control over energy management with extra safety functions. Demo implementation of Smart Distribution Box is composed of Energy Control modules and management applications running on mobile phones and Linux/Windows systems.
