An Integrated Platform for Incresed FLEXIbility in smart TRANSmission grids with STORage Entities and large penetration of Renewable Energy Sources

Periodic Reporting for period 2 - FLEXITRANSTORE (An Integrated Platform for Incresed FLEXIbility in smart TRANSmission grids with STORage Entities and large penetration of Renewable Energy Sources)

Reporting period: 2019-05-01 to 2020-04-30

FLEXITRANSTORE aims to contribute to the evolution towards a pan-European transmission network with high flexibility and high interconnection levels. This will facilitate the transformation of the current energy production mix by hosting an increasing share of renewables. Novel smart grid technologies, control and storage methods and new market approaches will be developed, installed, demonstrated and tested introducing flexibility to the European power system.
Following the current trends and EU regulations FLEXITRANSTORE has identified two main strategic objectives:
•To enhance and accelerate the integration of renewables into European Energy systems.
•To increase cross-border electricity flows across Europe.
The main outcome of the project will be a set of tools aimed to aid TSO operations, to assess the flexibility state of the grids and to facilitate the incorporation of increased flexibility. The tools have a broad timeframe, ranging from the Day-Ahead scheduling and balancing frame, to strategic planning of the future grid. Moreover, novel business models will be developed, in order to pave the way towards a pan-European energy market. All these tools will be incorporated into a common platform, with a unified architecture, the Flexible Energy Grid (FEG) Platform, which is expected to constitute the technical and operational basis to support the valorisation of flexibility services in the European Energy Market.
"During the first 18 months of the project the following achievements can be reported:
• Addressed the ethical issues and requirements of the project
• Performed a survey on grid flexibility among major stakeholders of the electricity value chain and academics
• The reference architecture of the three-stage methodology to integrate innovation technology into flexibility studies has been finalised.
• Regulatory gaps and impacts relating to flexibility were identified, and a basic techno-economic assessment for flexible services was performed.
• The impact of regulatory changes, market design changes was analysed as well as emerging business models for flexibility.
• An exhaustive analysis of the demonstrators’ requirements was performed and the first detailed conceptual Architecture of the FEG platform was designed.
• The design, analysis and the detailed engineering phases for each one of the demonstrators has been finalized.
• The DLR sensors of WP7 have already been installed on power lines in Slovenia and Bulgaria and the whole system is operational.
• The HIL simulation lab of WP10 has been set up in Seville and is operational.
• Prepared and/or participated in communication and awareness raising activities promoting the project and its results in web, social and physical means:
o The project logo, flyer, poster, general presentation, website and social networking sites on LinkedIn and Twitter, all of which are
continuously updated with progress and achievements.
o Participation to events at national and European level (conferences, events, workshops, EU clustering Events)
o Organization of a Webinar: “Towards a flexible European electricity system – business models, markets and regulation"".

Within the second reporting period (M19-M30) the following achievements can be reported:
• The flexibility study methodology developed by WP2 was applied to the cases of Greece, Cyprus, Bulgaria and on PCI projects.
• Global energy storage business models were studied in detail with emphasis on ownership type, technology, and market options served. Further, three business model canvases were defined for high potential lively combination of large-scale storage applications.
• An enhanced wholesale market design was proposed for an improved intraday market for flexibility trading.
• The first prototype of the FEG platform has been delivered. Some of the modules developed by the rest of the WPs have been integrated and are operational.
• The engineering, construction and integration of the container for the BESS and local BESS SCADA development have been performed for the case of the ADN demo in Cyprus.
• The BESS system of a wind farm is at the final stage of assembly and manufacturing tests, before being deployed in Greece. A local SCADA has been designed to monitor the status of the batteries and converters.
• The DLR de-icing demo has been operational for more than a year. The sensors for the de-icing solutions demo have achieved important milestones in year two with successful installation at both test sites in Bulgaria and Slovenia.
• The Power flow controllers were installed in the Greek demo site. The relevant tests were performed. The devices were decommissioned from the Greek substation.
• A new market platform was developed by ED to host the matching algorithm developed by BME. This module is fully integrated within the FEG and is currently in use by project participants and external users as well.
• The design of the SCADA systems to be deployed within two of the demonstrators of the project has been successfully finalized.
• The platform simulating the operation of the PI-BESS has been finalized. The services that can be offered by such a hybrid power plant were successfully showcased.
• The first activities of WP12 were successfully concluded, including the works on steady-state and dynamic-state models, the development of the gray-box and black box models, etc.
• The communication and dissemination material of the project has been updated. Social media were frequently updated.
• The project participated in various events and exhibitions.
• 3 videos were published.
• A book was published which includes a number of Scientific papers produced by the project.
• Newsletters were issued.
• Timely and appropriate trouble-shooting, immediate reaction to problems and adequate use of all project resources by the project and technical management."
The project takes both a national and regional approach acknowledging the need to seamlessly integrate national markets, particularly in the SEE region. The project will contribute to solutions, relieving internal congestion issues, via e.g. market based demand response mechanisms and the integration of storage, among other problems that are currently being faced. In summary:
a. The Power Flow Controller that was installed in Megalopolis’ Extra High Voltage substation will help solve congestion problems in the transmission network.
b. The DLR technology also increases power flows and allows redistribution of active power flows, so decreasing significantly the needed investments in the HV grid that need to be done with further penetration of RES.
c. The wind storage integration in Aisimi High Voltage substation will provide ancillary services to the grid while smoothing its volatile output. Thus, the integration of Variable Renewable Energy Sources will be supported.
d. WP5 and WP9 are dealing with the installation of a battery and the development of an enhanced electricity market in Cyprus.
e.The combined work of WP3 (enhanced market design) and WP4 (FEG platform) has defined use cases and functionalities supporting an enhanced market for flexibility.
Innovations in FLEXITRANSTORE will replace conventional, time-consuming and capital intensive grid reinforcements; thus limiting the network charges in the electricity bills for the end consumers. Furthermore, they promote RES integration and market coupling thus reduce even more the cost of electricity.
