1. Text Computational Optimisation for Smart Energy Systems Eric Pauwels, CWI, Amsterdam EIT Digital funded collaboration between CWI, TU Berlin, TU Delft

2. 2 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

3. 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

4. Collecting, analysing and visualising data Sensor networks Smart meters Databases for big data Data analytics and machine learning

5. 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?

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