Periodic Reporting for period 3 - FLEXITRANSTORE (An Integrated Platform for Incresed FLEXIbility in smart TRANSmission grids with STORage Entities and large penetration of Renewable Energy Sources)
Berichtszeitraum: 2020-05-01 bis 2022-04-30
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 project takes both a national and regional approach acknowledging the need to seamlessly integrate national markets, particularly in the SEE region. In summary:
a. The Power Flow Controllers that was installed in Megalopolis’ Extra High Voltage substation and later on in Dobrich Substation solved congestion problems in the transmission network.
b. The DLR technology also increased power flows and allowed 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. Moreover it facilitated the mitigation of potential icing events on conductors.
c. The wind storage integration in Aisimi High Voltage substation provided ancillary services to the grid while smoothing its volatile output. Thus, the integration of Variable Renewable Energy Sources was supported
d. WP5 dealt with the installation of a BESS at the interface between the TSO and the DSO and allowed the provision of ancillary services, the more efficient management of the grid and the ability to host more renewables.
e. WP9 showcased the operation of a novel market for flexibility in Cyprus and Bulgaria and introduced new order types, aiming to increase liquidity in the intra-day timeframe.
f. The combined work of WP3 (enhanced market design) and WP4 (FEG platform) has defined use cases and functionalities supporting an enhanced market for flexibility.
g. An advanced PSS installed in Bulgaria (WP12) managed to successfully damp oscillations and led to a more stable system operation which can be easily compromised in a system dominated by RES.
Innovations in FLEXITRANSTORE can 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.
