Multi-criteria optimisation for offgrid marine renewable electrical production

Duration: 36 months (2022-2025)


Isolated sites and microgrid are among the most relevant markets for marine renewable energy systems. Designing the electrical system and its integration must be optimized carefully in order to cover the needs at a realistic cost. The traditional optimisation method focuses on fixing the adequation between production and consumption with optimised energy converter and storage power. This approach can be improved by considering optimisation criteria from other fields of disciplines: reliability, machine position, electrical grid, carbon dioxide estimation, consumption control, cybersecurity and electrical stability. Previous works underline that sequential optimisation does not allow an optimal production system.
