In 2019, the European Commission published the “2030 Clean Energy for All Europeans” package, as part of the 2050 Energy roadmap. To comply with the European directives, Italy published the National Energy and Climate Plan setting a target of 55% for RES share in electricity generation by 2030. This high RES generation target raises concerns about the operational flexibility of the Italian power system. The flexibility of the Italian power system was measured using currently available flexibility frameworks and indexes (e.g.: AFPER, FAST2). Hence, the 2030 Base Scenario and 15 alternative scenarios were simulated using Promed Grid, a market tool developed by CESI and able to perform a coordinated hydro- thermal dispatching over a one-year horizon, considering the adoption of some flexibility sources such as storage systems and demand response. The results were then compared to characterize the performance of each flexibility source and its influence on the power system. BESS, PHS, and DR showed a level of complementarity while covering flexibility needs and controlling price spikes. Daily needs are covered mainly by BESS and weekly needs by PHS, mainly during the summer since both technologies were more used due to high solar power generation. Conversely, peak shedding DR was primarily activated in winter since prices are higher and storage systems lees used. In the case of V2G and DR, the role of aggregators is vital to have a representative capacity to be offered in the power markets. Finally, from a holistic perspective, the benefits of implanting all flexibility source are higher than the costs. Nevertheless, such benefits should be redistributed to incentivize the deployment of certain sources with low benefit-cost ratios. The results of this thesis can serve as a starting point to delve into the technical performance and economic implications of each flexibility source. In addition, it highlighted the advantages for Italy of boosting and supporting some schemes such as DR and V2G, as well as incentivizing the installation of storage systems.
