  • 1. Cassandra platformChristos DiouPostdoctoral ResearcherInformation Technologies Institute(CERTH-ITI)
  • 2. Cassandra platform – Christos DiouOutline• 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• NoI members and the platformCassandra 1st Webinar 2

  • 20. Cassandra platform – Christos DiouWhat if…• The residents of Apartment 1 use the water heater less– Because they have installed solar water heating• The residents of Apartment 2 use their air conditioning unit less– Because they have upgraded their apartment’s thermal insulationproperties• The residents of Apartment 3 replace their refrigeration unitCassandra 1st Webinar 20

  • 50. CONSUMER SOCIAL NETWORKS(CSN)Cassandra platform – Alpha versionCassandra 1st Webinar 52
  • 51. Cassandra platform – Christos DiouCSNs• 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
  • 52. Cassandra platform – Christos DiouCSN module• CSN module: A tool for identifying links and grouping ofconsumers in a meaningful way– Existing social network connections– Explicit attributes (e.g. working, non-working person, locality in the gridtopology)– Implicit attributes (e.g. consumption similarity, peak similarity, behaviouralsimilarity)• Early version implemented for experimentation• Next version:– More similarity criteria– Estimation of group response to incentives– GUI integrationCassandra 1st Webinar 54
  • 53. The main graphical interfaceof the CSN module
  • 54. The network can be createdbased on Installation Type,Person Type, Average, Peak,Similar, or DissimilarConsumption, etc.
  • 55. CSNetwork based on persontype. Persons of the sametype are linked.
  • 56. By changing the visualizationlayout algorithm….
  • 57. The two different person typesappearVisualization is Important!!!
  • 58. A new network based on PeakConsumption similarity
  • 59. We select the clusteringalgorithm to use
  • 60. Clusters appear in differentcolours
  • 61. By grouping clusters…
  • 62. The different consumergroups appear
  • 63. Another network based onsimilar consumption
  • 64. Change the edge thresholdvia the appropriate slider
  • 65. Select a clustering algorithm
  • 66. Clusters appear in differentcolors
  • 67. Various statistics areavailable, as well as theconsumption and informationof selected nodesSliders for minimum edgeweight and clustering values
  • 68. Cassandra platform – Christos DiouIn summary, with Cassandra you can• Simulate working scenarios/pilots• Benchmark different energy efficiency solutions/products insimulation 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 theapplication of targeted incentives
  • 69. Cassandra platform – Christos DiouSo, what’s next?• Beta release is planned for October, 2013• Integration of external modules with the platform• Evaluation of Cassandra in our three project pilot cases• Evaluation of Cassandra in a limited number of NoI pilots(external evaluation)• We can use Cassandra to simulate your context and benchmarka number of working scenarios.– Use measurements and the training module to model your context– Simulate a range of scenarios appropriate for your business case– Prepare an analysis/report of our findings– Ask for your feedback– Improve the platform based on your comments
