Flex-Offers: Unified generalized modelling and management of flexibility in electricity demand and supply

This page summarizes open resources underlying the Flex-Offer technology.

Overview

In collaboration with partners, AAU-Daisy has developed a universal unified way to represent / model flexibilities in electricity consumption and production, and this generalized model is called a “Flex-Offer”. This concept and the underlying technology have been developed in a number of EU FP7, H2020 and Danish Innovation Fund projects. Below, we provide references to these projects, as well as the key artifacts, summarizing the main findings and contribution.

To get an overview, we suggest the following references and the reading order: P19, R1, S1, P9, R3, R2.

Projects

MIRABEL (2010-2013) - developed a scalable ICT system for (1) Higher RES integration; (2) Demand-supply balancing; (3) Flex-offer management
TOTALFLEX (2012-2016)– developed and demonstrated a market-based system for flexibility trading and congestion management
Arrowhead (2013-2017)– it’s the largest European automation project of all time; It focuses on collaborative automation and interoperability of networked devices in (1) production, (2) end-user services, (3) smart buildings and infrastructure, (4) electro-mobility, and (5) markets of energy.
DiCyps (2015-2021) – makes a fundamental research on how to utilize software and data for smarter solutions in heath, traffic, energy, and community service domains
GoFlex (2016-2019)- a Horizon 2020 project, which integrate and demonstrate a group of smart-grid technologies for the cost effective use of demand response in distribution grids
