How to apply

When developing energy management strategies for hybrid renewable energy projects, explore and implement optimisation algorithms (e.g., genetic algorithms) that consider multiple objectives like profit maximisation and carbon reduction, rather than relying solely on predefined rules.

Project actions

01When modelling energy systems, consider using optimisation algorithms to find the best operating points.
02Investigate the potential for components to operate outside their standard ratings for short periods to improve overall system performance.

Method & Evidence

AimTo design, implement, and compare energy management strategies and optimisation approaches for a hybrid system integrating tidal stream energy with green hydrogen production.

MethodSimulation and Optimisation

ProcedureIndividual system components were modelled, and the annual performance of a tidal stream energy plant was simulated using real-world data. A rule-based energy management strategy was applied to analyse the electrolyser units' operation. An optimisation approach using a genetic algorithm was then formulated to maximise system operating profit under real constraints, prioritising tidal energy for hydrogen production. A cost-benefit analysis and comparison with the rule-based approach were conducted.
