Telecommunication Operators as Market Facilitators:Liberalisation of Energy Data & Home Energy Hubs
Marjan Šterk, XLAB
Radovan Sernec, Telekom Slovenije
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?
