Abstract
As decarbonization of energy systems becomes imperative and the deployment of intermittent
renewables increases, the operation of electrical grids becomes challenging. In this sense, tidal barrage schemes can
supply clean and predictable energy with more flexibility
than the more traditional wind and solar plants. However,
the high infrastructure costs associated with tidal barrage
plants, together with ecological and environmental issues,
hinder their deployment. An optimal operation is key to
maximise energy output and assure project feasibility.
Recently, Ringwood and Faedo [1] introduced a novel
approach to tidal barrage control by applying moment-based optimal control, previously used to solve wave energy control problems, with promising results. The model
consists of a two-way tidal barrage scheme, where an
analogy is made between latching/declutching algorithms
applied in WEC control and holding/sluicing from tidal
barrage operation. This preliminary study has a number
of simplifying assumptions, leaving a pathway to further
examine the optimal control problem.
This paper extends the results of the analysis from
[1] by adding enhancements to the model. Minimum
and maximum head values are added to account for the
turbine’s operational limits. The basin is modelled such
that the surface area is a polynomial function of the water
level, instead of assuming a constant surface area, which
will affect the operational head of the optimal solution.
Furthermore, a weighted cost function is introduced to
penalise the parasitic energy consumption of the sluice
gates, with an analysis of the impact of different weights.
