OPTILE
Multi-criteria optimisation for offgrid marine renewable electrical production
- Duration: 36 months (2022-2025)
- Budget: €1,550K
Context
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.
Objective
- To propose economic and environmental solutions for the supply of isolated electrical grids
Scientific content
Bibliography on offshore renewable energy sources and storage: price, maintenance, reliability, lifetime, system life cycle, CO2 impact, implantation
Key performance indicators calculation for multi-criteria approach: failure, machine position, coast, optimised electricity price
Development and implementation of a multifactor joint optimisation method
Real-time simulation of an electrical network taking into account cyber security aspects
Application cases : island, aquaculture and oil & gas infrastructures
Expected results
- Development of a method to select and size the optimal offshore renewable energy for an isolated microgrid
- Validation of the method by real-time co-simulation of electric and communication grid
- Definition of a new key performance indicator to optimise renewable energy farm
- Application of the reliability method to an extended optimisation system
