Latest news from the X-FLEX pilots

So far Albena (Bulgaria) has performed several tests for mFRR provision with the Bulgarian TSO – ESO EAD, also partner in the project. The tests proved that Albena can offer its flexibility for ancillary services with different assets such as boilers, battery, and biogas power plant. Some of the results have been published in Energy Magazine “Energetika”. Albena has also participated in BRIDGE activities.

In Ravne na Koroškem (Slovenia), Petrol partner views the development of new business models that will enable the green transformation of energy sector (heat and power) and are resistant to changing conditions as “the key to market success”. For this purpose, Petrol invested in a 6 MW HV-electrode boiler in the Ravne na Koroškem integrated economic zone – an industrial complex. The HV-electrode boiler will help to develop and test a model for generating heat from renewable energy sources (RES Power2Heat), which will improve the reliability and efficiency of district heating by optimising the use of CHP units and the HV-electrode boiler. The main purpose of the HV-electrode boiler is to provide frequency control (mFRR) services. Petrol is in the process of pre-qualifying the HV-electrode boiler at the Slovenian TSO. After that, it will be qualified to provide system services through the flexibility offered by HV-electrode boiler and help Slovenia’s electricity grid.

In Xanthi (Greece), Sunlight, as microgrid operator (with RES and storage) and HEDNO, as the distribution network operator, shall join their forces to explore their potential, to ensure the safe and seamless operation of the network under various conditions. Sunlight’s microgrid has been prepared with additional equipment allowing the operation of their microgrid in connection with the distribution network. This, combined with the use of GRIDFLEX, SERVIFLEX and MARKETFLEX tools, will allow the implementation and testing of scenarios where flexibility provided by Sunlight to HEDNO could reduce the impact of extreme weather events in adjacent parts of the local network and facilitate congestion management considering the expected increase in RES penetration.

In Luče (Slovenia), project partners will develop a solution for managing domestic charging infrastructure for electric vehicles (in an area with network restrictions and a large share of RES), which will support the expansion of electric vehicle charging and the inclusion of RES. For this purpose, 9 household smart EV chargers have been installed. The implementation of the household smart EV chargers has started to the home energy management system tool, which already enables the management of PV, household batteries, and other flexible units.

One of the goals in the project is also the development of new local market mechanisms and methods of capacity management in the distribution network. For this purpose, the partners Petrol and Elektro Celje have started an implementation test of the community grid fee calculation on an hourly basis. Based on the gained experience, new mechanisms will be proposed to the Energy Agency.
