Bridging the Gaps Final Event: Managing Resource Networks with a Generic Open-Source Software Platform

  1. 1. Managing Resource Networkswith a Generic Open-source Software Platform Julien Harou University College London UCL Bridging the Gaps Conference 16 February 2011
  2. 2. CollaboratorsBTG funding Lazaros Papageorgiou, Andy Chow, Mark Barrett, Eric FragaUCL Research Challenge funding Muki Haklay, Eric Fraga, Sarah Bell, Michael Batty, Tim SwansonHydroPlatform Design team (alphabetical order) Kristiana Hansen, Josue Medellin, Didrik Pinte, Manuel Pulido-Velazquez, Arnaud Reynaux, David Rheinheimer, David Rosenberg, Amaury Tilmant
  3. 3. Outline• Sustainability and resource systems• Systems modeling software• HydroPlatform• Example applications• Project organisation• Conclusions 3
  4. 4. Sustainable City … Sustainable Resource NetworkWater resources, energy, food, transport, trade, logistics, social networks, … 4
  5. 5. Systems modeling in the 21st Century • Large problems • Multidisciplinary • Many spatial and temporal scales • Computationally complex • Simulation, optimization, and mixed • Data intensive • Require sophisticated user interfaces 5
  6. 6. Traditional stand-alone software / DSS Interface Database Examples HEC products Model(s) DHI products Riverware WEAP etc. 6
  7. 7. Model Platform Manages & displays model Interface Database inputs & outputs Export/importOpen-source, functions or add-insfreeware, or proprietary models Model Model Model Model A B C D 7
  8. 8. HydroPlatform an example platform for network models• Free, open source (GPL license & Python)• GIS interface (Thubian) Database• Customize node and link objects• Several plug-ins Inter- Data face base Phase B: Phase A: Import & display enter, model results manage, & (next step) export data (completed)• International effort Model 8

  11. 11. Define required data for each network object 11
  12. 12. Example Applications 1. London water supply and Thames water resource system2. Water Supply Capacity Expansion and Trade in England 3. Zambezi Basin Hydropower Traffic Optimsation Network Analysis 12
  13. 13. English water management context• Water supply & waste water utilities privatised since 1989• Companies must submit environmental and financial water plan to regulators (EA, Ofwat) every 5 years• Companies have incentive to invest in capital schemes (i.e. prefer a desalination plant to sharing supplies with neighbor) 13
  14. 14. London and Thames water resource system 14
  15. 15. London and Thames water resource system IRAS-2010 model uses a weeklyGoal: time-step over 85-year time horizon- Predict London water with a runtime of 1 secsupply systemperformance underclimate change- Robust, meetsenvironmental targets 15
  16. 16. Gauged flow at TeddingtonIRAS-2010 and AQUATOR show same flows and follow trend for gauged flow 16
  17. 17. Capacity Expansion and Water Trading Schematic Goal: - Identify minimum cost portfolio of supply and transfer options to meet future demand - Uses ‘Economics of Balancing Supply & Demand’ framework 17
  18. 18. Annual rainfall Water companies
  19. 19. Zambezi Basin Hydropower dam operation Goal: Find allocation policies that maximize agricultural, hydropower and ecological benefits 19
  20. 20. Linear-Quadratic traffic signal controlGoal:Model optimises real-timecontrol of traffic lightduration 20
  21. 21. Linear-Quadratic traffic signal control• Input – Traffic inflow 120 – Nominal ‘fixed’ timing LQ feedback control plans 100 Fixed time control – Traffic light cycle Total Number of queued vehicles time, green durations 80 – Max storage and flow of each link 60• Output 40 – Queue lengths 20 – Optimal ‘dynamic’ timing plans 0 0 10 20 30 40 50 60 70 80 Cycle
  22. 22. Finding community structures in complex networks using mixed integer optimisation Goal: reveal the relationships between individual objects and their groupings in networksCommunity of 62bottlenose dolphinsliving in DoubtfulSound, New ZealandEach node represents adolphin and the links inthe network areidentified based on thesignificantly frequentcommunications amongthem. 22
  23. 23. Project organization• www.hydroplatform.org• Wiki, code, and bug reports• Pre-release available• Future app store open-source, proprietary, freeware models 23
  24. 24. Conclusions• Model platform = user interface + data manager• Helps focus on model development rather than software• Efficient, flexible, scalable, open-source platform• Goal: catalyze model innovation and use• Coming soon: ‘App store’ for HydroPlatform add- ins• Applications: general simulation, capacity expansion optimisation, water trading, traffic control, network analysis, etc. 24
