Energy transition •More renewables in the energy mix

• Solar and wind are intermittent sources•More decentralized energy generation

• From consumers to prosumers•Many stakeholders

• Industry, politicians, citizens• Collaboration and competition

•Result: Increased uncertainty

Dealing with increased uncertainty

•CWI: Centrum Wiskunde & Informatica• Dutch national Research Centre for Mathematics and ICT• Fundamental research focusing on problems

of societal importance

•Strategies to deal with increased uncertainty• Big data analytics and visualisation, (e.g. sensors, smart meters)• Innovative market mechanisms (e.g. stabilisation thru dynamic pricing)• Uncertainty quantification and prediction• Simulation of complex systems

Collecting, analysing and visualising data

•Sensor networks•Smart meters•Databases for big data•Data analytics and machine

learning

Simulation-based exploration: what if…?•What are new markets and market-mechanisms?•What is the likely impact of technological or societal developments?

• Distributed storage, EV’s, …• Sharing economy?• Autonomous vehicles?

Simulation-based exploration: what if…? •New markets for smart grids (in collaboration with EIT Digital)

Advanced mathematical models for uncertainty reduction

•Risk quantification: • Accurate estimation of rare

event probabilities

Advanced mathematical models for uncertainty reduction

•Smart approximations to improve computational tractability

Advanced mathematical models for multi-scale simulations•Electric discharge in plasmas: e.g. DC networks

High Performance Computing to enable technological breakthroughs

•Controlling instabilities in nuclear fusion reactors

Predicted output for Deuterium fusion

Current production and consumption

Partnerships with EIT Digital and many others…

In conclusion•Focus on generic and fundamental problems

• Directly relevant for society

•Wide-ranging applicability • Market mechanisms, • Optimisation in smart grids and smart cities• Innovative technologies

•Collaboration with EIT Digital to explore business cases•Interest in collaboration with partners and stakeholders
