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?

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
