6 Energy transition: The need for change Climate change CO2 reduction Al Gore More efficient use of energy Saving of natural resources Sustainable resources Efficient use of resources. 6

7 Sustainable resources: a paradigm shift in energy networks: Production follows demand Demand follows production Peak Renewable energy Flexible production Semi-peak Wind Sun Base Base 0H 24H 0H 24H 7

18 Digitisation of the grid Smartgrid: the expectation 18

19 How consultants see it: a lot of ICT 19

20 What utilities probably will need 20

21 The internet of energy Energy 1.0 Energy 2.0 Centralised Distributed 21

22 Distributed generation and consumption Require (Active) load balancing between supply and demand (and storage) Centralized central knowledge and control -> DSO distribution system operator Decentralized decentral knowledge and control -> LSO local system operator = one of the scenarios (but with the biggest impact) 22

23 The concept of the local system operator LSO transformer area low voltage 23

24 The concept of the local system operator LSO transformer area 24

25 Local balancing: Limits of the network Voltage* High Capacity* Overload Powerfactor* < 0.5 Low * only as an example but also Power quality Short Circuit Current Inertia Frequency stability >

26 Local balancing: Limits of the network Voltage High Capacity Powerfactor Overload < 0.5 Market facilitation Low Market facilitation Market facilitation >

27 Local balancing: Limits of the network Voltage High Capacity Powerfactor Overload < 0.5 Market facilitation Market facilitation Market facilitation Low > 0.9 Security of supply (SOS) 27

28 Local balancing requires control Control of generation Who is in control? Control of consumption Control of storage picture kind courtesy of 28

29 Responsibility of the DNO: Control DNO Responsible for control DNO Take action when SOS is in danger = 29

30 DNO role as LSO DNO Take action when SOS is in danger = active control over electricity network!!!! Communication 30

31 DNO role as LSO = active control over electricity network!!!! ADSL RF LTE Communication PLC DECT MPLS 31

32 Communication requirements for SmartGrids real time (near real time) Robust: availability, reliability Secure: cyber moderate speed: 1-10kbps Wireless challenges Coverage: power/duty cycle technology control backwards compatibility Cost of ownership Ease of operation (baystations) 32
