Abstract: Optimising the operation of tidal range schemes is a long-standing and critical problem in their design. Enhancing the efficiency and accuracy of optimisation methods is essential for maximising energy output and economic viability. In this study, we introduce the optimal control theory to model the optimisation problem and implement a dynamic programming algorithm to determine the optimal operation strategy for the West Somerset Lagoon and the North Wales Lagoon. To the best of our knowledge, this is the first application of the dynamic programming approach to solve the operational optimisation problem for tidal range schemes. Integrated into a zero-dimensional modelling framework, our algorithm demonstrates accurate and efficient forecasting of the scheme's operation, and the solution is guaranteed to be globally optimal. Furthermore, the model shows potential for real-time application and can be extended to the optimisation of multi-block units.
