MaREI’s ‘Control Systems’ capabilities focus on the active control of marine renewable energy devices, which can be used to optimise power production, observe system constraints, and minimise ‘wear and tear’ on components. The ‘Control Systems’ team work closely with the ‘Device Design, Testing and Evaluation’, ‘Power Take-Off’ and ‘Modelling and Simulation’ teams to provide a holistic and integrated approach to the optimisation and advancement of MRE Technologies. Research activities include the direct interconnection and synchronisation of generators in the field, the development of software/simulation tools for enhanced device control and increased power capture, and the formulation of energy-optimising control algorithms to exploit specific features unique to given devices.
Intelligent control systems must be employed to manipulate the power take-off (PTO) resistance so that the resonant frequency can effectively track varying sea conditions. In this regard, the maximisation of captured energy, through the application of intelligent control techniques for a given device specification, is vital if marine renewable energy is to become economically viable.
