• For making the tidal barrages cost-effective, new methods should be implemented to increase the produced power of them. For this purpose, this study suggests new techniques for optimally operating of the basin-based tidal units equipped to hydro-pumps. • According to the proposed technique, to increase the produced power and consequently the produced energy of the basin-based tidal units, at each time step, the number of turbines, sluices and hydro-pumps is optimally determined to yield the maximum produced energy of the generation unit using of different heuristic optimization approaches. • For satisfying the effectiveness of the suggested approach, optimal operating of a basin-based tidal unit installed on the estuary of Bacanga is done and impact of optimally dispatching of the turbines, sluices and hydro-pumps on produced energy of tidal unit is studied. Among different renewable energy-based power plants, barrage type tidal power plants with high installed capacity can be integrated in the bulk power systems. However, due to the high investment cost associated to the construction of the barrages and related components, barrage type tidal power plants are less developed than other renewable resources such as wind turbines and photovoltaic farms. In order to economize the production of electricity from barrage type tidal power plants, it is necessary to reduce the cost of generated electricity by these power plants with new methods. For this purpose, the plant is considered to generate the electricity in the ebb mode, and using the hydro-pumps the height of the water in the reservoir is increased in the flood state. Based on this fact, in this paper, to maximize the generated energy of the barrage type tidal power plant, an optimal design is proposed and the effective parameters of the plant including the number of turbines, the number and width of the sluices, the turbine diameters and the number of hydro-pumps are determined using of three optimization techniques including particle swarm optimization method, genetic algorithm and imperial competition algorithm.
