Energy@home: an eco-system approach to Smart Consumption & Demand Side Flexibility

Energy@home Association

2 www.energy-home.it

Non-profit Association founded on July ’12. Networking & pre-competitive tool

Scope: smart home & demand side management, not limited to the italian market

Goal: create a market for new Value Added Services based upon device-to-device communication and demand side management

Approach: Open and International Standards, trials & regulations

Liaisons with ZigBee Alliance, EEBus

Energy@home starting point

A Smart Home able to communicate and provide value added services:

> making users aware of their consumptions > driving users towards efficient behaviours

> supporting users to exploit ToU Pricing > making demand side flexibility a service of the home

Communication is the main enabler of these scenarios (Device2Device in the HAN, …)

Eco-system:

– A single service provisioning

architecture

– Interoperable devices

• Standards (protocols + data models

+ use cases)

• The future is in integration!

– Single Box

– A unified homogenous user experience

In the longer term a cross-services

partnership-oriented horizontal solution

will win versus vertical independent silos

solutions

Energy@home vision: Smart Home Eco-system

www.energy-home.it

Interoperablity is one of main requirement for the Energy@home eco-system implementation

Interoperability is the ability that systems have to exchange informations and use them in order to perform required functions

Semantic IOP level (ontologies, data model)

Syntactic IOP level (messages obtained by applying rules)

Interoperability is required both at semantic and syntactic level

Energy@home could be one of the apps@home …

Energy@home approach: Open and International Standard

http://www.energy-home.it

On Jul. 2011, Energy@home and ZigBee Alliance signed a collaboration agreement that brought to the ZigBee Home Automation 1.2 standard

Market leader with most deployed low power wireless mesh standard

EEBUS

On Dec. 2012, Energy@home and EEBus E.V. Initative signed a collaboration agreement with the goal of converging on a common (and standard) Data Model EEBus sets the focus on open and inter-operable standards with the goal of permitting energy suppliers and households to exchange apps and services to improve comfort and efficiency

Why ZigBee

Energy@Home power profile

Power Profile Sequence of electrical loads activation / deactivation (Power phases); basic “uninterruptable” elements:

Expected duration Peak Power consumption Maximum activation delay Expected Energy consumption

• Sequence of Power phases -> Power Profile

• Derives from IEC TC57 use cases

• Represented in UML

– Automatic mapping to XSD & to REST

resources

• Extends IEC Common Information Model

Model & IEEE P2030.5

– Function-centric approach

– Vocabulary of function types, function

schemas

• Provides following Function Sets:

– Device Information

– Monitoring&Control

– Metering

– ApplianceStatistics

– ApplianceEvents&Alerts

– PowerProfile

– Time

• Includes a tutorial with a SEP2 mapping

example & all the steps to generate Java

classes from the XSD representation files
