From Distribution Network Operator (DNO) to Distribution System Operator (DSO)
Agenda

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

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

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 ?

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

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)

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

re-architecting the grid edge

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 ?

• Result of true DSO-TSO cooperation
• Launched 29th january 2019,
by all Dutch DSO’s & TSO Tennet
• Building on the existing Intraday Market, easy
access for market parties
• Mitigating local congestion by procuring
spreads (re-dispatch)
• Platform supports TSO-DSO coordination to
avoid mutual harmfull interference
• First implementation in Europe

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

will this be (part of) our evolving landscape ?
for discussion

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
