Introduction HGI is an industry forum of

Broadband Service Providers

Manufacturers of Home Gateways, Networks, Chips, Software

HGI sets technical requirements for all facets of the digital home: Home Gateways, Home Networks, Services

Home Energy Management and Control is of active interest service to HGI.

Outreach has started to external organisations representing the smart meter and different technical facets of this service

HGI’s Energy Efficiency Work

Phase 1

Energy Efficiency of home gateways

HG test program including energy efficiency

Phase 2

Energy Efficiency of the home network and end devices

Phase 3

Energy Management and Control Service

DRAFT ONLY – NOT FOR PUBLICATION – COPYRIGHT HGI Phase 3 – Home Energy Management and Control

Consumers need to understand, visualise, monitor, and control the energy being consumed in their home

• Awareness lower consumption

Various approaches from

Energy Providers

Smart Meter

Over the top providers

Broadband Service Providers (BSP)

HGI is articulating the role of BSP & looking for collaboration among the different players

Broadband Service Providers

Energy related service providers

White goods manufacturers

End-User

DRAFT ONLY – NOT FOR PUBLICATION – COPYRIGHT HGI

Motivation and Business ModelEnd-User

Saving money – no additional revenue, some revenue displacement (utility > ASP)

Being Green – minimal additional revenue

Ancillary Services – possibly some additional revenue

Service possibilities

Inform

Analyse

Advise

Control

Ancillary – security etc.

DRAFT ONLY – NOT FOR PUBLICATION – COPYRIGHT HGI

Motivation and Business Model - IIUtilities

Electricity Generator Sell as much electricity as possible

Reduce peak to mean ratio of supply – reduce costs at power stations

Electricity Distributor Ensure continuity of supply

Avoid local overload

Avoid investing in new distribution infrastructure

Peak shifting AND load shedding

Electricity Retailer Sell as much electricity as possible

Possible revenue from Green information, but will not fully compensate for reduction in electricity revenue

DRAFT ONLY – NOT FOR PUBLICATION – COPYRIGHT HGI

Motivation and Business Model - III

Overall – not a lot of new revenue, some displacement, stickiness, and cost savings

Opportunity for BSP – to focus on the end-users services of home energy management – NOT the smart grid piece

Overall HGI HEM Architecture

DRAFT ONLY – NOT FOR PUBLICATION – COPYRIGHT HGI

Why the HG as the HEM controller ?

Always there – unlike Smartphones, laptops

Always on – unlike PCs

No great dependency on OS – unlike PCs

Support for third party applications via SWEX

Managed

Good linkage into HANs

But….

Not ubiquitous (BB, HGs, EE HGs)

Competitive area

Not a lot of new revenue

Use Cases Clusters1. Visualization of current energy and power data

2. Visualization of historical data

3. Alarm in different events

4. Home Domain Overload management

5. Optimize energy cost

6. Demand response

7. End User Control

8. Consumer/Prosumer tariffs simulator

14

DRAFT ONLY – NOT FOR PUBLICATION – COPYRIGHT HGI Visualization of current energy and power data Aim: to provide information to the customer on their current

energy consumption

6 sub cases: Visualization of total current energy consumption

Visualization of total current consumption + cost information

Visualization of current energy consumption of Smart Appliances + total consumption

Visualization of the current energy consumption of Smart devices + total house consumption + cost information

Visualization of estimated energy consumption of Smart Appliances and the cost before starting the Appliance

Information on energy mix

15

DRAFT ONLY – NOT FOR PUBLICATION – COPYRIGHT HGI

Visualization of historical data Aim: to provide customers with historical and

statistical information on their energy consumption, providing both the total energy consumed with time, and that of individual appliances

4 sub cases: Visualization of the historical data for the customer (total

in-house consumption and that of individual Smart Appliances)

Visualization of historical data compared with a benchmark Visualization of historical data charged at a new tariff Visualization of consumption data compared to that in

previous time intervals

16

DRAFT ONLY – NOT FOR PUBLICATION – COPYRIGHT HGI

Alarm in different events

Aim: to provide alarms promptly to customers

4 sub cases:

Notification of Home Domain Overload

Notification if a user configured limit is reached

Black out

Abnormal appliances consumption

17

DRAFT ONLY – NOT FOR PUBLICATION – COPYRIGHT HGI

Home Domain Overload management

Aim: to encourage the use of appliances when there is enough power in order to avoid overloading

2 sub cases:

Home Domain Overload management in the case of smart and non-smart appliances

Request confirmation to start if the available power (in the home) is not sufficient to run a Smart Appliance

18

DRAFT ONLY – NOT FOR PUBLICATION – COPYRIGHT HGI

Optimize energy cost

Aim: the system performs actions in order to reduce and optimize the energy cost. The optimization of energy cost in case of multi-tariff contract and configuration of a monthly cost limit

3 sub cases:

Multi-tariff energy use optimization in the case of smart and non-smart appliances

Automatic time shifting of some phases or functions of the Smart Appliance for favourable economic conditions

Configure cost limit

19

DRAFT ONLY – NOT FOR PUBLICATION – COPYRIGHT HGI

Demand response Aim: it takes into account possible requirements related to the

future interaction between clients and the electricity market The customer could be presented with daily (or even hourly) offers

coming from the current energy supplier or possibly alternative suppliers which aim to modify clients’ behaviour. Such offers could be via by a new player in the energy market called the Aggregator, who has the business objective of aggregating many small customers and to offer this aggregated set to the energy market. The Aggregator could offer the following capabilities to an energy supplier: Power limiting within a given geographical region and temporal slot Peak clipping Peak shifting

1 sub case: Demand response management

20

End User Control

Aim: to provide the customers with the ability to control all appliances within their Home Network

4 sub cases:

Appliance configuration

Start/Stop appliances

Override of HEMS recommendation by user

Unsuccessful override of HEMS recommendation by user

21

Consumer/Prosumer tariffs simulator

Aim: to provide customers with the ability to optimize their tariff. The customer can choose the best tariff from each provider, simulate the consumption with that tariff and then change tariff if they wish

2 sub cases: Compare provider tariffs and simulation of the user

consumption with a new tariff

Compare provider tariffs and simulation of the prosumer new tariff

Architectural Issues

How the functionality/logic controlling the home energy management is split between the local control within the home and remote control from the cloud (utility/service provider/3rd party) ?

Composition of HG/EG

Integrated

HG with “dongle” for home networking support

Subtended EG

What data must flow from the smart meter to the HG/EG

Smart appliances: should the logic be concentrated in the HG/EG or distributed

27

DRAFT ONLY – NOT FOR PUBLICATION – COPYRIGHT HGI

Configuration/Addressing questions

MAC based, proprietary, IPv4, IPv6

Is it necessary to support IP and non-IP addressable devices ?

How is initial configuration done with regard to:

Address allocation (if any)

Device discovery

Network topology discovery

How are shared medium devices, in particular wireless attached, constrained to attach to the intended network ?

28

DRAFT ONLY – NOT FOR PUBLICATION – COPYRIGHT HGI

Security and Privacy Questions

What level of security is required with particular regard to appliance control ?

What mechanisms are needed/proposed to guard against DOS and terrorist attacks ?

Required levels of privacy

Summary

Home Energy Management service is being addressed through HGI and collaborating groups

Addressing the home management/control service as opposed to the smart grid piece

Key architectural issues are being worked in partnerships with many industry partners

Smart meter – HG data transactions are an important part of this
