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

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
