  3. Organizational readiness (1): Overall drivers for change • Agility and acceleration require a multidisciplinary approach • Realizing the targets of energy transition is a multidisciplinary challenge • Strong interaction between Markets, Technology & Regulation • In 2025 the DSO business will be predominantly a digital business • “bitts control watts” and “the grid as a platform” • Building digital competencies is key • The future energy system will not be bounded by existing organizational structures • Preparing for ecosystem alignment • Re-architecting the existing IT/OT/IOT landscape to align in the future business ecosystem Converged skill sets Markets Friction Friction Energy Market Strategy Business IT Technology Vendors Expert oriented skills sets Regulation Technology
  4. Organizational readiness (2): Preparing for new ecosystem alignment 1. Real-time energy distribution 2. Grid analysis & planning 3. Infrastructure Operation 4. Customer, market & data management Corporate Services & Data 2030Agility through loosely coupling Defining the scheduled grid maintenance & inspection portfolio Defining the grid expansion/ renewal/ reconstruction portfolio Executing of the portfolio Executing of the portfolio Physical Grid Asset Risc Manage ment Investment & Grid strategy Market & Customer Interaction Account management Data Management (smart meter, A&R) Customer Service CRM & Billing Service & asset restoratio n Real Time Energy Distribution Municipalities End Customers Commercial Market Parties End Customers End Customers Analytics & IOT DSO processes 2018 DSOs core business can be characterized by 4 core activities Each of the 4 core activities (worlds) has : • Its own characteristics an challenges in the energy transition • Its own dynamics, in relation to the external environment, which between themselves differ in direction & speed Agility from the technology landscape can be increased by: • Creation of strong focus and cohesion per world (efficiency & effectivity) • Loosely coupling as much as possible between these worlds The 4 worlds are supported by a 5e corporate world: • Containing typical corporate functionality (eg HR, FIN, LT) • Governing corporate data: data which is common and used in the 4 worlds -> “Loosely coupling” supporting business agility while maintaining overall business value
  5. Customer acceptance of smart assets: • Simple in use → automated operations • Low cost → large addressable market • Freedom of choice → no lock-in solutions Customer assets - grid integration, meaning: • Solving the grid challenges at high DER penetration rates • Increasing LV grid observability This requires: • De-facto standards, creating a market • Grid connection agreements to be enhanced with a logical interface • Additional regulation on access to data & services • New DSO market facilitating services via DERMS ? DER-Agnostic Grid DER- Aware Grid DER-Leveraging Grid DER-Centric Grid • Levels of DER are insignificant • Grid ignores connected DER • Levels of DER become noticeable • The grid is aware of the presence of DER, and accounts for them in distribution planning and operations • Levels of DER become useful • The grid makes use of DER, taking advantage of the services that they can provide Levelofregulatoryawareness EvolvingUtilityChallenges • Levels of DER become mission-critical • The grid depends on certain behaviors and/or services of DER in order to operate effectively Stages in DER-Integration Research based on Challenges on the grid edge: the integration of customer smart assets
  6. Key Question: Selecting platform(s) for the future ? • Seamles edge- cloud computing, also as basis for distributed SCADA systems • Cloud options: IAAS, PAAS, SAAS • Public or private cloud • Commitment of the developers community • Scope: IT OT IOT • Excellent cyber security Answering this question requires: • Assessing technical capabilities of platform options (POC) • Monitoring market momentum of relevant market players • Deep understanding of cloud business models • Vendor willingness to cooperate in the eco system with other vendors • Correct timing in investment decisions (not too late/ too early) Edge computing Connectivity Cloud computing Distributed platform IOT based platforms: recognizing the industry trends The grid emerging as a platform: “bitts control watts”
  7. The transformation of the technology market Who will be the winners ? No other “core” ERP considered for now (eg MS Dynamics or IFS) Post-modern 2025 options (some examples) Customer Engagement Meter Data Mgt (EDSN) Enterprise Asset Mgt Operational ERP / Project Lifecycle Administrative ERP Analytics, Big Data Platform (Advanced) Distribution Mgt Field Service Mgt IoT Platform E-Terra + new GUI + “App” Process & Data Intregration Platform IAAS PAAS SAAS? ?
  8. Smart meter roll out: • Existing architecture based on designs 2004 • Making the meter smart Challenge: • Smart meters supporting new market/regulatory requirements: o Demand response, more realtime data, etc. o New communications technologies • How to leverage realized smart meter investments ? This requires a smartmeter roadmap >2020 • Making the meter dumb again (like IoT sensors) • Introducing add-on technology (gateway) on existing meters • Implementing an edge- cloud computing architecture • Gateway also to support DER – Grid integration The future of the smart meter a roadmap >2020 is urgently needed CENTRAL DATA PLATFORM DATA COMMUNICATIONS LOCAL APPLICATIONS LOCAL DATAPLATFORM LOCAL COMMUNICATIONS SENSORS & MACHINES AMI Head End (incl.CRYPTO) PLC/ GPRS/CDMA 5G/LTE/NB- IoT Dataplatform (cloud computing) Smart meter DSMR Versions 2.2, 4, 5 Local interface G-Meter E-Meter Connected Devices (Wireless) M-Bus Multi Utility Gateway (Edge Computing) App 1 App n … G-Meter E-Meter HEMS Smart Inverters (Wireless) M-Bus … App 2 REMOTE APPLICATIONS App 1 App nApp 2App 1 App nApp 2 re-architecting the grid edge
  9. Trends • Market fragmentation, due to competition • Many TSO DSO flex-platform pilots • One system, but multiple system operators • Costly, complex and potential system risks Needed • True TSO DSO coordination on equal footing • Clarity on who coordinates what ? • EU Regulation Flexibility Platforms Are we going the right way in Europe ?

  11. The challenge • More grid dynamics (weather & dynamic pricing) • The DSO grid is not a copper plate any more ! • Real time is not enough, what will happen in 1 hour ? Needed: • Need for deeper grid behaviour insight & predictive monitoring: • “day ahead” & “intraday” load & generation forecasts in 15 min, intervals of distribution grids, GLDPM compliant • Additional regulation on quality of BRP forecasts • Using smart meter data: PQ & load analysis for optimal grid operations & planning • DSO’s willing to learn from TSO’s Forecasting in Day Ahead and Intraday A new necessary competency required by DSOs
  12. EMS/DMS (SCADA) Day Ahead/ID Forecasting Flex Procurement (GOPACS) DERMS Netmodel (GIS) • Dynamic netmodel • Request action (deviation actual from forecast) Forecast Curves (to validate actuals against) • BRP forecasts • Weather data • Metering data Congestion case Notification Congestion Case solved Receiving bids • Market notification • Request to match spreads DER-Grid Control DER –Grid Monitoring Static Netmodel Static Netmodel Activating Flex Markets Monitoring Flex (RT) GridCustomer Assets ControlControl MonitoringMonitoring Market Grid Interactions will this be (part of) our evolving landscape ? for discussion
  13. Challenges: • Affordability of the system, who shall pay the costs ? • How to balance between societal and individual grid charges ? • How to protect the vulnerables ? • Renewables generation (PV, Wind) and dynamic pricing may increase the grid peak baseload ration by a significant factor (up to 4x) Needed: • Differentiate between “grid access” and “grid usage” • Define different energy grid services with different tariffs (can be implemented with one smart meter) Differentiated grid tariffs A reflection on grid tariff structure is needed Traffic light based tariff system
