Abstract

Abstract: Model predictive control is used for revenue maximisation in a network of Ocean Batter- ies. If efficiency is assumed to be high, the model intuitively decides on energy storing and draining operations. This model was however built on assumptions simplifying its behaviour. Efficiency has proven to vary during draining operations, from literature and has been quan- tified with previous research on the Ocean Grazer. This study investigates the validity of the current model and subsequently, the model will be complemented with this varying ef- ficiency. This altered behaviour of the model after implementation will be analysed and discussed. Every turbine has a different ’efficiency curve’ which plots the efficiency against the dimensionless flow-rate, i.e. with respect to its best efficiency point. In the conceptual Ocean Grazer set-up, which serves as a basis to this research, the use of a pump running as turbine is proposed. The model is generalised in such a way that simulations can be done both with standalone as well as pumps running as turbines.
