New technologies are reaching every sector, and power is no exception. To address this change, power transmission & distribution systems need to optimise the integration of renewables and manage the complex interactions between consumers and generators. This adaptation will require an investment of €7bn to 2035, according to IEA estimates. Given this scenario, smart electrical grids, as well as the development of distributed generation, will play a key role, as they will reduce the costs of this technological shift and increase the reliability of the energy model of the future. Funded by the European Commission and coordinated by CIRCE, the MEAN4SG project, which is training eleven young researchers who are preparing their doctoral theses on smart grids, is being developed within this field.
