1. Cassandra Network of
Interest Webinar
Welcome to Cassandra
A multivariate platform for assessing the impact
of strategic decisions in electric power systems

2. Welcome to the Cassandra Webinar
 During this Webinar we will review:
 2. Concept and theoretical aspects of CASSANDRA
– By Giorgos Andreou, Lecturer at Power Systems Laboratory Department
of Electrical and Computer Engineering Aristotle University of
Thessaloniki
 3. Explanation and demonstration of CASSANDRA Modeling
Platform
– - By Christos Diou, Postdoctoral Research Associate at Centre for
Research and Technology Hellas ITI - CERTH
 4. Next steps and opportunities in platform development
for NOI Members
 5. Questions
Cassandra Webinar Network of
Interest

3. Network of Interest
 Bring together stakeholders who can provide insight on
possible user requirements
 Form a community of possible users
 Allow companies to either test the platform or have their data
processed
 Enable interested parties to adapt this open source platform for
commercial use

Power System Status – the near future
 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!

6. The Consumer
 Individual consumption is insignificant with respect to the
consumption of “bigger” players (Industrial, Commercial,
Public Service, Recreational)
 However aggregate small-scale consumption is significant
– Entire residential and large part of the commercial sector
 In fact, consumer modeling is difficult to achieve, due to:
– Lack of metering equipment (i.e. smart meters)
– Inability to model consumer activities
– Inability to model response to incentives (Demand side)

7. Filling the gap… Cassandra!
A software platform for modeling the energy
market from an end user perspective
 Main Cassandra objectives:
1. Theoretical and software modeling of stakeholders in terms of
energy profiles and consumption patterns, as well as their
interactions
2. Increase the market power of low level consumers through
Consumer coalitions (Consumer Social Networks - CSNs)
3. A Key Performance Indicator (KPI) methodology, in order to
assess energy performance and CO2 emissions reduction
4. A modular, expandable software platform to model and
benchmark scenarios and act as a Decision making tool.
