“…Herein, the produced energy of the TPPBB is determined considering various numbers of turbines, starting head and generation capacity. In [9], an optimisation problem is solved to maximise the annual energy production of a TPPBB installed on the Bacanga Estuary. In this paper, a genetic algorithm is used for the determination of the optimum number of tidal turbines, and it is concluded that with an optimal dispatch of turbines during the generation process, it is possible to obtain a significant gain.…”

Tidal as renewable energy is increasingly utilised for power generation in many countries. Integration of tidal plants into the power system requires considering the intermittent nature of the generated power caused by variable tide levels. Thus, the reliability studies of power systems including high tidal generation affected by the uncertain nature resulting from the variable water levels are investigated. The reliability model of a tidal power plant on a barrage is proposed. In the proposed model, the failure rates of the composed components (especially the hydro pump and gate) and the effect of tidal height variation on the components failure rate are considered. Also, the reliability model with numerous states resulting from the variability of the generated power through the fuzzy C-means clustering technique and Xie-Beni index is reduced to a multi-state reliability model. The resulting reliability model is utilised for the generation adequacy studies of a power system containing large-scale tidal power plants. Moreover, different reliability indices are calculated for future generation expansion planning. The proposed technique is applied to the two-test systems, and sensitivity analysis is performed. Besides, the effects of the hydro pump, maintenance, ageing of the components and peak load are investigated.

Summary Increase in the penetration level of renewable resources results in the development of new approaches to assess the impacts of these variable resources on the power network. Large‐scale barrage‐type tidal generation units can integrate to the power network for reliability improvement. For reliability analysis of a power system containing these plants, a reliability model is developed. This model is considered the components' failure and also the output power variation arisen from the change of the tidal height should be developed. For this purpose, a multi‐state reliability model considering variation of tidal height that affects components failure rate and also the value of generated power is developed. The failure rate of components including transformer, turbine, cable, generator and electrical converter is dependent on the tidal height and turbine velocity. The paper is focused on the developing a thermal model for each component. Based on the temperature rise of the components, the associated variable failure rate is calculated from the Arrhenius law. The multi‐state reliability model of barrage‐type tidal energy conversion system considering variable failure rate of components is utilized to study the generation power systems adequacy based on the analytical and Monte Carlo approaches. This model is also utilized for reliability assessment of composite power system containing barrage‐type tidal power plants. Considering variable failure rate of components results in a more accurate reliability model for tidal power plant. Based on this model, the effects of different tidal patterns on the reliability indices can accurately be studied.
