3. Christos Diou (CERTH/ITI) - Outline of the Platform’s Operation and Main Features Presentation Transcript

  • 1. Cassandra platform Christos Diou Kyriakos Chatzidimitriou Postdoctoral research associates CERTH/ITI A multivariate platform for assessing the impact of strategic decisions in electric power systems 1st CASSANDRA Workshop Coventry, 11 September, 2013
  • 2. Outline • Library-based scenarios in the alpha platform version – Use pre-existing library components • Measurement-based scenarios – Model training to build models automatically • Response models – Consumer response to different incentives • Consumer Social Network analysis – Grouping of small-scale consumers into Consumer Social Networks • Development status and next steps
  • 3. About the platform • Currently in alpha version, development is highly active – Some functionality has not been integrated yet • Open source platform, publicly available through GitHub – http://github.com/cassandra-project – Apache license 2.0
  • 4. LIBRARY-BASED SCENARIOS Cassandra platform
  • 5. Login screen
  • 6. Main screen Main panel Libraries Projects and entities
  • 7. List of projects
  • 8. List of projects
  • 9. User library
  • 10. User library
  • 11. Cassandra library
  • 12. Cassandra library
  • 13. Appliances in Cassandra library
  • 14. Appliances in Cassandra library
  • 15. Creating a new project
  • 16. Creating a new project
  • 17. Adding a new scenario to our project
  • 18. Installations can be added by drag’n’drop from the user library
  • 19. Persons, Activities, Appliances
  • 20. Persons, Activities, Appliances
  • 21. Activity models
  • 22. Activity models (duration)
  • 23. Activity models (start time)
  • 24. Simulation parameters
  • 25. Simulation parameters
  • 26. Submit runs
  • 27. Submit runs
  • 28. Scenario 1: A mall • What if … – Roof-Top-Units (RTUs) are shut down 1 hour prior to mall closing time taking advantage of thermal inertia in the sales area? – Gradually start A/C units from 08:00-09:00? – Set points from 21 to 24 degrees Celsius? – Shut down all office A/Cs after 22:00 with manual override? – Set the minimum fresh air from 20% to 5%? – Change escalators from always on to escalators with motion sensors?
  • 29. Baseline and test-case scenarios - Change a set point
  • 30. Baseline and test-case scenarios - Change duration
  • 31. Comparisons
  • 32. SCENARIOS WITH MODEL TRAINING Cassandra platform
  • 33. Training module
  • 34. Import installation measurements
  • 35. Import installation measurements
  • 36. Next step: Disaggregation
  • 37. Training consumer activity models
  • 38. Training consumer activity models
  • 39. Export the models to the platform libraries
  • 40. Models are visible in the user library
  • 41. CONSUMER RESPONSE Cassandra platform
  • 42. Response models
  • 43. Modify pricing scheme
  • 44. Estimate consumer response
  • 45. Modify pricing scheme
  • 46. Models are posted to the platform
  • 47. Models are posted to the platform
  • 48. Example 1: Response from … to
  • 49. Example 2: Response from … to Complete change of habits
  • 50. After 100 Monte Carlo runs of baseline and response scenarios …
  • 51. Comparison of runs
  • 52. CONSUMER SOCIAL NETWORKS (CSN) Cassandra platform
  • 53. CSNs • Groups of similar consumers – Multiple similarity criteria • CSNs have potential: – Increased market power of aggregated small-scale consumers – Coordination of consumption activities at group level – Targeted incentives at group level
  • 54. CSN module • CSN module: A tool for identifying links and grouping of consumers in a meaningful way – Existing social network connections – Explicit attributes (e.g. working, non-working person, locality in the grid topology) – Implicit attributes (e.g. consumption similarity, peak similarity, behavioural similarity) • Early version implemented for experimentation • Next version: – More similarity criteria – Estimation of group response to incentives – GUI integration
  • 55. The main graphical interface of the CSN module
  • 56. The network can be created based on Installation Type, Person Type, Average, Peak, Similar, or Dissimilar Consumption, etc.
  • 57. CSNetwork based on person type. Persons of the same type are linked.
  • 58. A network based on similar consumption
  • 59. Select a clustering algorithm
  • 60. Adjust the clustering parameters
  • 61. Clusters appear in different colors
  • 62. The different consumer groups appear
  • 63. In summary, with Cassandra you can • Simulate working scenarios/pilots • Benchmark different energy efficiency solutions/products in simulation before testing them in real-life • Create detailed models that describe consumer behaviour • Identify and evaluate optimal consumption schedules • Estimate consumer response to a range of incentives – Pricing schemes – Consumer awareness – Environmental impact • Identify meaningful consumer groups and benchmark the application of targeted incentives
  • 64. So, what’s next? • Beta release is expected before the end of 2013 • Further development and integration of response and CSN modules • Integration of external modules with the platform – thermal controllers, lighting models • Evaluation of Cassandra in our three project pilot cases • Evaluation of Cassandra in a limited number of NoI pilots (external evaluation)
  • 65. Thank you! Questions?
