D2.3 Final data model, specification of request and negotiation messages and contracts

The aim of the MIRABEL project is to exploit potential flexibility in both demand for and
generation of electricity to compensate for the intermittent nature of Renewable Energy
Sources (RES). For instance by postponing certain electricity demand until energy from a
RES (e.g. solar panel) becomes available.

In order to leverage flexibility in demand and generation means for expressing and
communicating this flexibility are needed. For this purpose, this MIRABEL deliverable
provides a data model. This document contains the final version of the data model, a
previous version of the data model was presented in deliverable D2.2 which was
published in December 2010.

The aim of the data model is twofold. Firstly it serves as a means of alignment between
the various work packages ensuring proper co-operation of all the components involved
in the MIRABEL Electricity Data Management Systems (EDMS). Secondly there is an aim
for standardization; the data model (and messages specifications derived from this
model) is input for an active standardization process that is the subject of WP7.

The central concept of this data model is FlexEnergy; which is used to describe flexibility
in consumption or production of energy. It is crucial for the project to have a common
view on FlexEnergy as it plays an important role in the work packages on aggregation
and scheduling. The model that is specified in this deliverable is the result of various
discussions within the project as well as feedback from the first version of the model.

Apart from the update of the existing model this deliverable also contains an XML
schema that was derived from the data model. The purpose of the XML schema is to
facilitate the implementation of the data model.
