Smart metering l.jpg

Smart metering


Present technology l.jpg

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 l.jpg

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 l.jpg

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 l.jpg

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 l.jpg

Examples for realisation


Smart metering in austria l.jpg

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 l.jpg

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 internet11 l.jpg

Smart metering and the Internet


Smart grids l.jpg

Smart grids


Smart grids13 l.jpg

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 grids14 l.jpg

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 grids15 l.jpg

Smart grids

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


Advantages l.jpg

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 l.jpg

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


Historical development18 l.jpg

Historical development

traditional grid vs. smart grid

ABB, 2009 „Auf demWegzumintelligentenStromnetz“


Examples for realisation in austria l.jpg

Examples for realisation in Austria

BundesministeriumfürVerkehr, Innovation und Technologie, 2009 „IntelligenteEnergiesystemefür die Zukunft“

  • National pioneering projects

  • Smart consumer: municipality Großschönau -consumers as key players

  • Smart services in Greater Linz

  • Vöcklabruck: intelligent measurement and information system

  • Biosphärenpark Grosses Walsertal: smart distribution grid

  • Smart infrastructure in Salzburg

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


Model region salzburg smart infrastructure l.jpg

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 l.jpg

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
