Smart metering

Present technology

• electric meter device which measures the

amount of consumed electric energy

• consumption in Kilowatt hours

• Ferraris-meter most common technology

– Magnetic fields: consumer electricity, consumer

tension

• multirate meters (industry)

• somebody has to read off the electric meter

Smart metering technology

• combine electric metering with two-way-communication systems

• communication systems– displays real use

– transfers meter data to the supplier

• flexible tariffs (peak-load-pricing)

• supports micro generation technology (wind turbines, solar panels)

• different types of payment (prepayment or credit)

• forecast energy demand

Advantages of smart metering

• exact billing (mathematical projection)

• energy savings (3%)

• reading off stops

• flexible tariff changes (tariff or supplier)

• just one needed meter (two locally placed meters)

• metering production & consumption (PV, mini cogeneration units)

Disadvantages of smart metering

• implementation costs (800 million Euro up to two

billion Euro)

• privacy (data privacy, consumer protection)

• inferences on customer behavior (through

permanent recording)

Examples for realisation

Smart metering in Austria

• About 40.000 already

installed

• Pilot projects

• Technology by Siemens

• Energy providers patient

• Huge competition

• Disadvantages

Smart metering and the Internet

• Software to track energy usage behaviour

• Microsoft Hohm – Google PowerMeter

• Software connected with data from energy

provider

• Currently tracking the energy use, in future

controlling?

Smart metering and the Internet

Smart grids

Smart grids

• Definition:

„electricity networks that can intelligently

integrate the behaviour and actions of all users

connected to it - generators, consumers and

those that do both – in order to efficiently deliver

sustainable, economic and secure electricity

supplies.” (The SmartGrids Technology Platform. 2006)

Smart grids

Smart grids should not be mixed up with smart metering, it includes much more technologies etc.:

 

The SmartGrids Technology Platform. 2006. “What is a Smartgrid?”

Smart grids

Environmental Stewardship Committee at VTS. 2009. “Smart Grid”

Advantages

• Environmental benefits

• Renewable energy

• Increased efficiency

• Security and reliability

• Money savings

• Integration of decentralized energy poducers

• Open energy market

• Disadvantages: costs, privacy, technology

Historical development

• Up to now:• grid with centralised power plants

• unidirectional load flow

• limited grid integration for new electricity producers

• top-down operational planning with previous data

• Current trend:• implementation of decentralised power plants

• multidirectional load flow

• grid integration for new electricity producers

• planning with real time information

traditional grid vs. smart grid

ABB, 2009 „Auf dem Weg zum intelligenten Stromnetz“

Examples for realisation in Austria

Bundesministerium für Verkehr, Innovation und Technologie, 2009 „Intelligente Energiesysteme für die Zukunft“

•National pioneering projects

•Vöcklabruck: intelligent measurement and information system

•Smart consumer: municipality Großschönau -consumers as key players

•Biosphärenpark Grosses Walsertal: smart distribution grid

•Smart infrastructure in Salzburg

•Murau: energy vision – fail-proof power-supply for the region

•Smart services in Greater Linz

Model region Salzburg – smart infrastructure

• Vision to become the first Austrian model region

concerning smart grids

• Tough challenge to implement a smart infrastructure

(geographic situation)

• Finding solutions of an overlapping cooperation between

the energy sources and the infrastructure components

Steps of development

• Actually the Salzburg AG runs 26 hydroelectric power

plants, two thermal power stations and several

photovoltaic systems and biomass plants

• Creation of a better grid integration for suppliers of

renewable energy

• To guarantee an active customer participation (clarify

how to handle information)

• Finding the best technology solution for the customers

• Advance the implementation of bloc heating works
