The increasing integration of renewable energy sources into the power grid has prompted a paradigm shift towards sustainable and resilient energy systems. On the other hand, the energetic flexibility offered by shiftable loads or storage devices brings new win-win solutions for the grid, businesses, households, and the environment. This work explores the concept of Energy Communities (EnCs) cooperative flexibility as a strategic approach to bolstering EnCs resilience. EnCs can influence collaborative efforts among diverse energy stakeholders to optimize energy production, distribution, and consumption. This PhD thesis reviews the key components of EnCs, such as decentralized energy generation, smart grid technologies, and energy flexibility, highlighting their potential to enhance the overall reliability and adaptability of the power grid. The existing literature exhibits a notable gap concerning the EnC resilience. Thus, this research endeavors not only to enhance the resilience of EnCs during faults or power deviations but also to discuss the concept of EnC resilience, incorporating energy flexibility as a pivotal component within the proposed methodology. A community made up of 30 households is considered to conduct a group of use cases, where energy storage system as well as photovoltaic systems are installed. The EnC's resilience is quantified by key metrics, proposed for this thesis, that allow analyzing the community's behavior regarding the user's needs in different situations. The conducted use cases' results show that the proposed Energy Community framework improves the resilience of the community, benefiting not only the community's users as well as the Distribution System Operator (DSO).
