2 Jörg Heuer | Siemens AG | München | Renewable Model Region Harz: Climate Protection and Energy Efficiency by Modern ICT and Innovative Operation Strategies Kurt Rohrig, Florian Schlögl Energy Economy and Grid Operation ISET e.V. Jörg Heuer Embedded Networks Corporate Technology SIEMENS AG

3 | Jörg Heuer | Siemens AG | Seite 2 von 12 Regulation targets stimulation of open Energy Markets Reduction of carbon footprint requires significant integration of RES Energy Systems under Change – The Drivers Unbundling in Energy Systems Dynamic coordination of volatile RES and DER ICT for loose coupling and integration of DER

4 | Jörg Heuer | Siemens AG | Seite 3 von 12 The German E-Energy Initiative Main goals of the E-Energy Initiatives ●Coordination of DER ●Based on ICT for ●Extensive use of renewables ●System stability and ●Market liberalisation E-Energy Initiative in a nut shell ●Funded by the Ministries of economics and ecology ●Six Model Regions have been selected ●Various, region specific approaches are studied ●A launch pad also for E-Mobility

5 | Jörg Heuer | Siemens AG | Seite 4 von 12 The Region Harz – An Introduction „The“ renewable region in Germany ●Already today the regions is penetrated by DER (***) ●Significant pump storage is available (***) ●DER is seen as a significant industry in the region by the local population and the politicians System limits are evident ●Power fluctuations is a challenge for the system stability ●In peak situations the transmission networks are not capable to transport the generated energy QuantityPN [MW] PV118 (500)2 (10) Wind135 (185)250 (350) BHKW52 (100)12 (25) Storage1 (2)80 (180) Household100 (1000)0,5 (5) Industry20 (40)100 (200) Electro vehicles3 (100)0,03 (1)

6 | Jörg Heuer | Siemens AG | Seite 5 von 12 Include RES, Loads and Storage Coupling by means of market mechanisms and control Interface with Grid Operation Support by massively distributed ICT systems Renewable Virtual Power Plant RES Controllable Loads Storage Control Communication Market Communication Approach studied – A Regional Virtual Power Plant

7 | Jörg Heuer | Siemens AG | Seite 6 von 12 Operation of RES – Wind Farm Cluster Management Coordination of distributed wind farms Coordination with the transmission network Taking weather information under account Already demonstrated by ISET © by ISET

8 | Jörg Heuer | Siemens AG | Seite 7 von 12 Electro Mobility – A Multipurpose Storage System Integration of eMobility ●Manageable load ●Manageable storage ●Potential: 89%  Rush Hour Integration of Domains ●Electrical Grid ●Varying Communication NW ●Logistics and Driver Info Practicability in the Project ●RegModHerz will be complemented by HarzEE-Mobility ●A mobility management system interfacing with the VPP ●Integration of eMobility to maximise use of RES

9 | Jörg Heuer | Siemens AG | Seite 8 von 12 System Coupling by Incentives – The Market Place Market Places ●Separation of a regional and a whole sale market place ●Introduction of dynamic pricing on the regional market place to couple consumption to generation ●Raises awareness of fluctuating energy resources ●A slow control loop by pricing signals is expected Bidirectional Energy Management Interface (BEMI) ●Price driven automation of device control (e.g. climate control) ●External interface based on CIM data models ●Internal interface is installation dependent (e.g. KNX)

10 | Jörg Heuer | Siemens AG | Seite 9 von 12 System Coupling by Control – The Technical VPP The ICT Gateway for Energy Management ●Enables status monitoring and control of massively distributed energy systems ●External Interface based on IEC61850 and web services ●Unified modelling of DER ●Internal interfaces are installation dependent (e.g. Profibus) Massively distributed ICT Systems ●Have to cope with a statistical loss of control ●Not engineerable systems ●Support of automatic administration ●Have to ensure system stability in stress situations e.g. by congestion control

11 | Jörg Heuer | Siemens AG | Seite 10 von 12 Technical Grid Operation – The VPP Backbone Status monitoring based on PMUs ●Increased precision of balancing ●Supports coordination of loads and generation ●Identifies the demand of aux services ●Strong requirements on the communication infrastructure Joint communication NW and electrical Grid simulations ●Based on Netomac and NS2 ●Enables large scale evaluation ●Demonstrates interdependencies between the networks PMU PCC 1 PCC 2 PCC 3 PMU U, I, f, t t P t PMeasurments: - f  global parameter - U, I  local parameters - t  global time stamp P,Q RKWH

12 | Jörg Heuer | Siemens AG | Seite 11 von 12 Conclusion and Outlook Conclusion ●ICT to loosely couple DER and RES aiming strategic triple ●For coupling market and control communication is deployed ●Fundamental challenge is the complexity of a massively distributed VPP Outlook ●Lab Tests by Q2/2010 ●Field trials are scheduled for Q4/2010 ●Complementation by HarzEE-Mobility project including eCar fleets
