Background 7 • The continuous growth of renewable energy sources (RES) had drastically changed the paradigm of large, centralized electric energy generators and distributed loads along the entire electrical system. • Nowadays, there are many renewable energy resources located much closer to industrial, commercial, or residential areas. This is called “distributed generation.” • Energy sources like sun and wind are not predictable and subject to sudden changes, furthermore, their integration with current thermoelectric plants is not easy. • Methods of managing the electrical system will need to be modified in response to changes introduced by renewable energy generation. • An energy storage system can provide relevant support to the electrical system for the integration of renewable energy sources
