Challenge / Goal
The Iberian market has an insufficient interconnection capacity with the rest of Europe under all network development scenarios, thus limited access to balance service providers. In addition the share of high variable renewable energy sources in Spain is relatively high. As an example of the high variability of RES in Spain, wind power was producing roughly 2 GW at 14:40 (contributing to 6.7 % of demand) on 26/01/2019 and less than 12 later, at 02:10 on 27/01/2019, wind power produced almost 11 GW (43.5 % of demand). More flexible demand is needed in the near future. This pilot explores the possibility that radio base stations of mobile phones networks can contribute the providing ancillary services through the local storage units installed for allowing this network to stay alive in case of electric distribution blackouts.
Base stations are equipped with back-up batteries. which ensure the continuity of communications service in the (rare) event of a blackout in the distribution grid. By using the back-up batteries, radio base stations can be disconnected from the grid on purpose when requested, releasing the flexibility required to decrease congestion and provide stability. A TSO-DSO control mechanism in which the DSO (Endesa) was responsible for a local congestion management in the distribution grid as well as for providing to the system balancing by enforcing an agreed exchange of power with the TSO (REE, which unfortunately was not part of the experiment because not member of the Consortium). The resources cleared in the local services market are not only the VODAFONE radio base station participating in the pilot but also other resources (e.g. PV and Electrical vehicles) that are however only simulated.
