PROJECT 24 – FleXunity

The objective of FleXunity project is to deploy novel services for retailers and aggregators, enhanced by Virtual Power Plant (VPP) technology empowered with AI algorithms focused on minimizing the cost of energy (bought in the wholesale market) and optimizing the use of distributed renewables from the utility or community portfolio. The proposed energy community approach will promote active participation of end-users (community members) valuating their flexibility and energy sharing actions, which will be supported by secure transaction mechanisms with technologies such as blockchain to validate energy transactions. These services will include a tariff structure optimisation design for the Energy Community to be able to meet the needs of the system operator by aggregating the flexibility to participate in balancing and ancillary services markets as a Balance Service Provider (BSPs). The key project outcomes will be achieved by testing and demonstrating the proposed services in two distinct pilots with very different market conditions: UK energy market (open mature market concerning the use of demand side flexibility); Iberia energy market (in transformation - opening to use flexibility from demand-side). Given the nonexistence of a common legal framework across Europe, this will help us to validate different stakeholder benefits in closed and open energy markets, which will enhance the full commercial roll-out after this 2-year project. These envisaged innovative services will allow utilities to maximize their profit and enable new business models from managing multiple energy flexibility assets, introducing flexibility as a new tradable asset in their business portfolios, and allow energy costs savings sharing with end-users, enhancing the use of renewables and support energy security and climate change challenges.

European islands have to abide by the law of their countries that push toward a greener energy mix to comply with the European and international agreements. GIFT is willing to develop innovative systems to allow islands to integrate vast amount of renewables. 
In order to reach that goal, GIFT will develop multiple innovative solutions, such as a virtual power system, energy management systems for harbours, factories and homes, better prediction of supply and demand and visualisation through a GIS platform, as well as innovative storage systems, allowing synergy between electrical, heating and transportation networks. GIFT will increase the penetration rate of renewable energy sources into the islands' grid, reducing their needs for diesel generation and thus decreasing the greenhouse gases emissions directly related to it.
During 4 years, the partners will develop and demonstrate the solutions in two lighthouse islands, in Hinnøya, Norway's largest island and the small island of Procida in Italy and study the replicability of the solution in a Greek and Italian islands at the minimum, respectively Evia and Favignana. The complementarity of these islands in terms of climate, energy mix, population and activities is meant to have solutions adaptable to different situations. The GIFT project has started to build a replication board with associations that already gather 1640 European islands able to study the replication for their territories. 
The consortium gathers 17 partners of 7 countries, including 1 industrial partner, 9 SMEs, two municipalities, 3 research centres and 2 universities with the aim to provide sustainable solutions with a strong market uptake and plans to widely disseminate their solutions and replicate it on all relevant islands in the EU and beyond.

The ongoing developments and achievements on protection, automation and control (PAC) systems for transmission grids, namely on IEC 61850 based solutions, provide new opportunities for real implementations and deeper research.

Inspired by the results derived from the 'Substation of the Future' project, where a specification for a new generation of PAC systems was developed and tested, the SMART SUBSTATION TESTING AND IMPLEMENTATION project aims to further develop the functionalities and extend the testing portfolio for PAC systems. Whilst performing the corresponding proof of concept at the laboratory, for further demonstration purposes, a real implementation in a transmission grid shall be evaluated.

The technical specification and corresponding testing protocols, already developed, will thus be customized for the real installation, considering its specific characteristics and the TSO requirements. A set of KPI will be defined for the implemented functions, which will allow evaluating its performance and of the overall PAC system.

With this project, the TSO will be encouraged to gain confidence in the new solutions powered by the new standards and technologies, contributing to a more efficient and reliable power system.
