The deliverable D4.14: Energy profile of Community Grid and EV users was submitted by MPOWER in June 2023 with contributions from ESBN. The executive summary of the deliverable is available below and the full deliverable is at the end for download:
“The goal of the +CityxChange project is to establish a Positive Energy Block/District in such a way that everyone who participates can share and trade their available energy resources locally within the Community Grid. The excess available energy at the level of the energy block thus established can be stored and used later when needed or sent back to the grid. Utilisation of local flexibility would enable smart optimisation of city level energy resources and achievement of Positive Energy Block/District. This document specifically looks at the use of flexibility trading and systems to be designed for it.
The Community Grid concept, as explained in deliverable D2.6, sets the necessary prerequisites for this to be realised, starting with the ICT infrastructure that connects participants, measures consumption and production, and manages controllable flexible assets.
Despite all efforts, the necessary structure for the establishment of the first Community Grid in Limerick could not be established within the project. First five PEB buildings were connected with electricity clamp meters and a communication infrastructure has been established by bespoke Smart Link Unit (SLU) devices that provide real-time two-way Smart M2M communication with the central HUB for monitoring of consumption / production. However, the planned organisational formation of a prosumer group, which is a prerequisite for the creation of a local energy market, was not realised.
The functionality of the existing MPower enerXchange is extended with the necessary energy/flexibility trading functionality, providing prosumers with the basic tools for trading of the available flexibility. The development of the application stopped there. The trading mechanism was developed as a first iteration, but it was not possible to test and demonstrate it live. True value of trading flexibility could not be demonstrated.
This deliverable explains the DPEB energy/resource trading system at the stage it has reached during the project timeline. It also contains insights and recommendations for the national regulatory authority (CRU), the DSO (ESBN), and the TSO (Eirgrid) in Ireland with respect to the potential for Community Grids and a Local Flexibility Market that have been identified during this development and implementation effort or from the ideation stage.”
