SEP 2 IP-based energy management for home

May 14, 2013

What exactly is smart energy profile (SEP 2) IP-based energy management for the home? Introducing the SEP 2, Tobin Richardson, chairman and CEO, ZigBee Alliance said ZigBee smart energy is the standard of choice for home area networks (HANs).

ZigBeeAbout 40+ million ZigBee electric meters are being deployed. ZigBee smart energy is being enhanced by network/communications options, support for forward-looking developments, etc. SEP 2 is a joint effort with the HomePlug Alliance. There is a vision of MAC/PHY agnostic SmartEnergy profile.

Robby Simpson, SEP 2 Technical Working Group Chair, system architect, GE Digital Energy, provided the features and benefits of Smart Energy. Features include price communication, demand response and load control, energy usage information/metering data, prepayment metering, text messaging, plug-in electric vehicles, distributed energy resources, billing communication, etc.

Example applications are many, such as smartphones, ESI in the sky, tablets, TVs, plug-in electric vehicles, PCs, solar inverters, thermostats, energy management systems, smart meters, building management systems, smart appliances, etc. There is support for a variety of architectures. The use of IP eases convergence and architecture changes. A consortium for SEP 2 interoperability (CSEP) has been established.

Skip Ashton, ZigBee Arch. review committee chair, senior apps director,  Silicon Labs said implementations of SEP 2 are available from a number of companies and across several MAC/PHYs. All standard documents are available for review.

Jeff Gooding, Southern California Edison (SCE), spoke about creating SEP 2 energy ecosysyems. SEP 2 can bridge multi-platform customer technologies to create a rich ecosystem. SEP 2 customer focused solutions can allow the utilities and energy service providers to use any customer communication channel. SEP 2 pilots at SCE include a gateway pilot and a smart charging pilot. Both are separate pilots.
