Cassandra
A multivariate platform for assessing the impact of
strategic decisions in electrical power systems

Center for Research and Technology –Hellas / Informatics and Telematics Institute

2. Power System Status – the near future
• Decentralized, small-scale production
sites
• Renewable energy
• Market liberation
• Smart grid
• More players involved
Big market potential unexploited!
 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

3. 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 support tool.

8. Cassandra methodology
• Five SE Phases
• Two-round iterative
software development
• Two Software prototypes
(early-final)
• Three Pilot Cases

9. Pilot Case 1:
Multi residential building
• Scope: To evaluate the Plants model User profiles
performance of the Cassandra Building
model
Weather
conditions
platform in a small scale
consumer network
• Main objectives: To test and validate
– Basic and Aggregate Consumer Modeling
– Load Modeling
– Heating/Cooling combined with building envelope
• Secondary objectives: To test and validate
– Consumer Network Modeling
– Behavioral aspects

10. Pilot Case 1:
Multi residential building
• Site: Residential building Plants model User profiles
in Northern Italy Building
Weather
model
• Specific Info: conditions
– Approximately 30 apartments
– Shops
– Monitoring and automated control equipment partially exist
• Methodology:
– Monitoring of the electrical and thermal consumption
– Modeling and Simulation
– Demand response and energy efficiency modeling and
implementation

11. Pilot Case 2:
Consumer Network
• Scope: To evaluate the performance
of the Cassandra platform in a
medium scale consumer network
• Main objectives: To test and validate
– Basic and Aggregate Consumer Modeling
– Consumer Network Modeling
– Behavioral Aspects
• Secondary objectives: To test and validate
– Load Modeling
– Heating/Cooling combined with building envelope

12. Pilot Case 2:
Consumer Network
• Site: Living Lab in Sweden
• Specific Info:
– More than 50 households
– SABER: a complete solution for the
full monitoring of energy consumption
• Methodology:
– Monitoring of the total energy
consumption
– Modeling and Simulation
– Research, modeling and implementation of behavioral stimuli
within the Consumer Network

13. Pilot Case 3:
Benchmarking lighting products
• Scope: To evaluate the performance
of the Cassandra platform as a market
enabling tool for a company
• Main objectives: To test and validate
– Load Modeling
– Strategic Planning capabilities
• Secondary objectives: To test and validate
– Basic and Aggregate Consumer Modeling

14. Pilot Case 3:
Benchmarking lighting products
• Site: UK, Germany,
sites of Pilot Cases 1 and 2
• Methodology:
– 2-3 lighting products will be developed
for deployment at different application
levels
– Factors affecting energy consumption for lighting will be
researched in the sites of Pilot Cases 1 and 2
– Modeling and Simulation

15. Assessable Outcome
• Cassandra is essentially a:
Modeling Software Platform
• To provide:
 Modeling of electrical installations (small or large scale, individual
or combinations of arbitrary number of installations)
 Knowledge regarding consumption patterns and demand-response
incentives
 Decision support (analysis of what-if scenarios)
 Open platform for energy companies/communities
(Global energy think Tank, PowerTAC)
 Empowerment of the end consumer
 Environment for studying change and sustainability

16. Assessable Outcome
• We expect to:
– Model accurately individual installations
– Model accurately the aggregated demand served
by a utility
– Offer the capability to understand macroscopically
the behavior and response of its customers
– Offer a tool that will either produce realistic
results with little effort, or dynamically produce
real results with considerable initial effort.

17. Assessable Outcome
• We do not expect to:
– Model accurately all individual customers of a
power utility
– Forecast the real response of individual
customers
