Hello Visitor,

Here is the December 2013 edition of the Odysseus Newsletter with news on the project, events and update on the test pilots.
 

The Odysseus team in Rome for the first year of the Project

After recently closing the first year of the Odysseus project, the project team gathered this time for the second General Assembly meeting in Rome (Italy) for the preparation of the results from the first 12 months project activity. Finally, the first concrete outputs are ready to be disseminated to the communities, the Energy Efficiency domain and all the interested related stakeholders.

The project team took the opportunity to visit one of the school buildings involved in the Rome pilot case and to take a close look at the physical energy installations that will interact with the Odysseus Cloud Platform and software tools.

Odysseus Energy Ontology taking shape

In Odysseus we distinguish Physical Networks (P-Networks) and Energy Networks (E-Networks). Both contain nodes and interconnections between these nodes, physically (P-Nodes and P-Connections) respectiveley energetically (E-Nodes and E-Connections).

P-Nodes cover real life objects and spaces on different scales also referred to as “Levels of Detail (LoD)” playing zero, one or more E-Node roles consuming and/or producing energy of any form (electricity, gas, thermal air/water).

Similarly P-Connections cover real world connections between P-Nodes like electrical cables, pipes, walls etc. playing zero, one or more E-Connection roles transporting in some way energy from one producing E-Node to another. consuming E-Node.

Energy Storage is treated implicitly in the end resulting in E-Nodes being able to consume and/or produce energy in more flexible ways. Physically energy can be stored by P-Nodes that can have an ‘energyState’ property (like the electrical charge of a battery or the thermal energy of a space).

We identified four main relevant LoDs:

  1. City (our starting context/scope)
  2. (City)Neighbourhood (urban area to be “energy managed”)
  3. (Neighbourhood)Element (like a Building, Windmill or ElectricVehicle)
  4. (Element)Part (like a Zone, Space, Laptop, Radiator., PVPanel or Sensor)

These four levels have a totally clean or ‘strict’ interface: Cities consists of Neighbourhoods, which consist of Elements which consists of Parts. Within Elements and Parts we can have more ‘unclean’ grouping like, for Parts: Zones consisting of Spaces consisting of InstallationParts and Appliances, but InstallationParts can also be direct parts of a Building).

All P-Nodes can have static properties (like the surfaceArea in m^2 of a Space or Zone) and/or dynamic properties (having varying values like temperature, humidity, occupancy, energyState etc.) which are modelled as “Profiles” that can have required, expected or measured values over the time axis including the past, the (ever moving) present and the future. Similarly, all E-Nodes have energy-oriented static properties and/or dynamic properties (like energyConsumption, energyProduction).

In Odysseus we stick to the so-called ‘black-box principle’ for scalability sake: on one level of detail we only consider the next level of detail but no deeper than that so for Neighbourhood Energy Management, the prime scope of Odysseus, we treat all Elements like Buildings as black boxes. We can apply the generic modelling on any layer but not mix layers opening up black boxes.

The Odysseus Team wish you all happy festive season!
