Distributed Energy Resources Integration
September 2016 in Denmark, one week (source Energinet.dk)
Growing complexity into Grid Situational Awareness & Flexibility Management

TYNDP 2018 : looking to 2040 Centralised and decentralised coexist
RES –up to 70% of demand, developed in non
coordinated manner with the network
Need for physical layer • Grid costs: 150 billion Euros in total (TYNDP2016):
new investments needed after 2030
• “No grid” in 2040 : extra bill by 2040: 43 billion
Euros/year
threaten reliable access to electricity
156 TWh/year of RES wasted (annual
consumption of BENELUX )
New System control strategies required for 2040 More frequency variation
Significant inertia reduction especially on small
systems
New transient stability aspects
Observability and controllability of distributed
resources and coordination between TSOs/DSOs
Flexibility needs
Duration curves : Wind and Solar / Total generation
Magnitude of the hourly ramping
Lower inertia trend especially in the small
synchronous area
Use of Interconnectors (VSC and AC)
Batteries
Super capacitators
Prepare for future sector coupling
• Power with Gas / Combined Heat & Power
• Mobility with Power & Gas & Emission Trading
• TSO-DSO coupling
• Microgrid coupling at Gridedge through #Blockchain

New ENTSO-E’s Cybersecurity approach
11
• Leadership MoUs with ENCS, CENELEC
Strenghten implication on EC Smart Grid Task Force
New ENTSO-E Cyber Strategy Policy Paper (Nov 2017
• Expertise Roll-out of the Integral
Security Framework (Sep 2017)
New Communication tool for Cyber Incidents (2018)
• Robustness New robust security
plans e.g. CGM Security Plan (Oct 2017)
Evolve Electronic Highway into new ATOM architecture
Target to build new Integrated Vision 2030
Access to Distributed Flexibility
Operating with millions of smart
devices
High RES and Network of the
Future?
Clean Energy Package including
Risk Preparedness
New R&D Tools and Processes
Optimizing Market Design

Which design changes will
support system
operation?
What R&D projects will be ‘operational’?
By 2030?
How can we manage smart devices at TX
level?
Can the network support high
RE?

New Hybrid AC/DC System
14
• Society dependence on electricity
• Increasing market dependence of HVDC
• HVDC Trips / Unavailability costs
Need for further HVDC Reliability
15
Current HVDC reliability levels
Average no. of trips per link and year 2005-2014
16
HVAC/HVDC System Interaction – Further work required to improve HVDC System integration
5 topics to further investigate • EMT modelling of hybrid transmission lines
• Identification of adverse interaction of hybrid systems under normal/unnormal/faulted operations
• Development of mitigation schemes
• Public acceptance of hybrid transmission systems
• Prediction of ionic currents in hybrid systems
