Workshop 3A: Water in Smart Livable Cities

2. CITIES in short
CITIES was launched January 2014 and is a 6 years research centre which has been financially supported with an excess of € 10 million from Danish Council for Strategic Research and commercial partners. It is involving a wide range of industrial and academic partners, 40 in total. See more at our homepage:

4. Challenge – Fluctuations
Demand: Gray.
Wind power production: Green.

6. The Concept of CITIES
Integration & IT-solutions for operation and planning for future energy systems

7. The proposed solution – Smart Grids
From centralized to decentralized production
But still demand for stabilization
Therefore the CITIES Research Centre

8. The Goal - Flexibility Can we shift load?
Author: Henrik Madsen, DTU Compute

9. CITIES – Hypothesis
The central hypothesis of CITIES is that by integrating distinct energy flows (heat, power, gas and biomass) in urban environments intelligently, we can enable very large shares of renewables, and consequently obtain substantial reductions in CO2 emissions.

10. Water and energy markets
Water market (large storage capacity)
Electricity (very little storage capacity)
heat market (reasonable storage capacity)
Interaction between the water and energy market.
