D2.2 Data model, specification of request and negotiation messages and contracts

The aim of the MIRACLE 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 MIRACLE deliverable provides a data model. This document contains the first version of the data model; a subsequent deliverable D2.3 will follow in M18 of the MIRACLE project and will provide further enhancements and elaborations.

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 MIRACLE 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 first 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 will serve as input for the work packages on aggregation and scheduling. The model that is described in this deliverable is the result of various discussions within the project.

The final version of the data model will be the subject of deliverable D2.3. It will contain refinements on the FlexEnergy structure based on the feedback from other work packages and a wider focus that includes all major data concepts that are used by each EDMS component. Not only will it focus on a data model but there will also be much emphasis on the actual messages that are exchanged between the various players of the energy market. [read more]
