  5. 5. The Consumer… 1st Cassandra Workshop Coventry, 11 September, 2013 • Individual consumption is trivial with respect to the consumption of “bigger” players (Industrial, Commercial, Public Service, Recreational) • Aggregated, however, small-scale consumption becomes significant • Small-scale consumer modeling is generally difficult due to: – The lack of respective metering equipment (i.e. smart meters) – The difficulty in modeling consumer activities – The difficulty in modeling response to incentives (Demand response)
  6. 6. Power systems – the near future 1st Cassandra Workshop Coventry, 11 September, 2013  Lack of tools for modeling the new Power System status  Inability to aggregate the market power of small-scale consumers  Necessity for dynamic models for assessing the impact of actions and policies to be applied • Decentralized, small-scale production sites • Renewable energy • Market liberation • Smart grid • More players involved Big market potential unexploited!
  7. 7. 1st Cassandra Workshop Coventry, 11 September, 2013 Filling in the gap… Cassandra! A software platform for modeling the energy market from an end user perspective • Main Cassandra objectives: – Theoretical and software modeling of stakeholders in terms of energy profiles and consumption patterns, as well as their interactions – Increase the market power of low level consumers through Consumer coalitions (Consumer Social Networks - CSNs) – A Key Performance Indicator (KPI) methodology, in order to assess energy performance and CO2 emissions reduction – A modular, expandable software platform to model and benchmark scenarios and act as a Decision making tool.
  8. 8. 1st Cassandra Workshop Coventry, 11 September, 2013 Cassandra platform • Disaggregation of load curves • Modeling of individual appliance consumption • Learning of complex consumption and activity models • Modeling distribution network aspects • Incorporation of demographics • CO2 emissions and environmental impact modeling • Extensive simulation capabilities • Simulation of demand response capabilities • Observation of simulated load curves and features at all levels of detail (individual appliance -> entire world) Measurements
  9. 9. 1st Cassandra Workshop Coventry, 11 September, 2013 Individual small scale consumers • Policies and consumption programs cannot be enforced • Modeling of acceptance • Consumer utility vs gain from incentives • Modeling based on consumption activity (not based on appliance switching) • Ability to simulate targeted incentives to consumer groups • Ultimately, ability to simulate a wide range of demand – response programs • Ability to adjust models based on measurements Measurements
  10. 10. 1st Cassandra Workshop Coventry, 11 September, 2013 Going even further: CSNs  Consumers have the option to selectively join coalitions (Consumer Social Networks) and respond to incentives
  11. 11. 1st Cassandra Workshop Coventry, 11 September, 2013 Cassandra vision
  12. 12. 1st Cassandra Workshop Coventry, 11 September, 2013 Stakeholder benefits • Aggregators and service providers – Model consumption, model consumer response to targeted incentives, support decisions and planning of novel products and services • DSOs – Simulate the network load at any point in the distribution grid – Understand why load peaks are observed and simulate solutions • Individual organizations, universities, municipalities – Model consumption policies, the gain in power reduction and the impact on the satisfaction of consumers – Optimize consumption by constructing an effective consumption program

  18. 18. Our vision for the Cassandra project • To become the point of reference in decision support and behavioural demand side management for small-scale consumers • Uptake from energy market stakeholders • Continuous development from the open source community past the end of the project Cassandra 1st Project Review Brussels, 11 Jan 2013 18 Residential Commercial • Aggregators • DSOs • Policy makers • Consumer groups • …
