Telecommunication Operators as Market Facilitators:Liberalisation of Energy Data & Home Energy Hubs
Marjan Šterk, XLAB

1. To research and analyse the ICT communication architecture to develop an intelligent Home Energy Hub and Home Energy Cloud service that will allow scalable, efficient, reliable and secure connection into VPP.
2. To setup a field trial consisting of 400 measurement points at 120 household or business sites.
3. To develop new business models connecting technology and business verticals of energy and ICT companies. New business models are required for successful mass adoption of smart grid home energy cloud in general.
Home energy hub: Objectives from R&D to business
Home energy hub & installation
Some requirements for VPP ready solutions at prosumers
1. Real time energy metering & reporting (< 1 min period)
2. Secure communication channel to VPP or DSO operator
3. User app with simple interface for energy profile tracking
4. ON/OFF manual or automatic capability
5. Integration with other smart grid market stakeholders
6. Upgrade path: meter smart meter + energy hub
Connecting the stakeholders and VPP
Stakeholders connections: Energy flows
Stakeholders connections: Information flows
Home energy hub: Starting point, winter 2012/2013
We want to measure:
power (real)
voltage
current
cos phi
•Total + individualcircuit breakers
We need on-off control
Off-the-shelf
• niche products
• proprietary, vertically integrated
• some public APIs
Custom hardware, what about communications?
•IP-based connectivity (4G LTE or 3G)
•Powerful (700 MHz ARMv6 CPU, 512 MB RAM)
•Free choice of upper-level communication protocol
•...or custom protocol?

Home energy hub within smart grid space
User app with minimalistic GUI: Simple
User app with minimalistic GUI: Informative
Web app GUI: Multi home energy hub dashboard per customer
Web app GUI: Single load tracking
Web app GUI: Single load with tracking, zoom in
Open interfaces: Open Power measurement dashboard
Open interfaces: Twitter notifications
Controllable loads statistics on field trial
Putting it all together
1. Complete home energy hub and cloud systems architecture
2. Message bus RMQ based cloud communication
3. Debian based FW/SW repository for long term support
4. Opening towards Web with Http
5. Value added services opportunities for utilities and operators
Opening up business opportunities via cloud
