Abstract

As the demand for electricity and the need for power systems flexibility grow, it is crucial to exploit more reliable and clean sources of energy to produce electricity when needed most. Tidal lagoons generate renewable electricity by creating an artificial head difference between water levels on the seaside, driven by tides, and water levels inside the basin, controlled by flow through the structure. Depending on the level of sea water, power generation from a tidal lagoon can be controlled, i.e. shifting power generation in time. This paper investigates the operation of a tidal lagoon in response to the fluctuating electricity prices. By developing an optimal operation model of the tidal lagoon, its schedule in the day-ahead wholesale electricity market was optimized to achieve the maximum revenue. The Swansea Bay tidal lagoon was used as a case study. It was demonstrated that by exploiting the flexibility offered by tidal lagoon, it can achieve a higher revenue in the day-ahead market, although their total electricity generation is reduced.
