- Abstract
- The response of many nations to address climate change, focuses on the decarbonization of the electricity generation and on the electrification of the industrial, transport and buildings sectors. The combination of these electrification strategies, together with the growth of population and global economies results into a very remarkable increase in electricity demand, which occurs simultaneously with a very important transformation of the electricity generation resources mix. This electricity generation resources mix transformation requires the retirement of the conventional polluting generation plants, which are replaced by the rapid addition of large amounts of RERs, especially, of the highly variable, uncontrollable and intermittent wind and solar PV resources. Therefore, as countries move closer to meet their decarbonization targets, the increased variability in electricity generation outputs, entails major challenges on the provision of the required grid operational flexibility in all time scales. In addition, the increased number of extreme weather events resulting from climate change, rather than just reducing the resilience of electricity grids, also pose additional sources of variability in RER electricity generation outputs over longer multi-day, multi-week and seasonal periods.LDES deployment is driven by their large power capacity, large energy capability, long discharge durations, their modularity and scalability. LDES technologies can become totally reliant on charging their units from RERs electricity supply and so, contribute to decarbonization. The main objectives of this work focus on the investigation of the drivers for LDES deployment and how they can be accommodated with the ability to enhance grids resilience, eliminate RER curtailments, reduce grid congestion and overall provide electricity grids with the increasing long duration grid operational flexibility required. To explain the contribution of LDES in a concrete electricity grid, we develop a case study, in which we demonstrate the needs of resilience and mainly of long duration flexibility that arise as the Spanish electricity system evolves according to the decarbonization objectives set by the EU.
