The traditional method neglects the characteristics of tidal water intermittency and fluidity, and the condition is unstable, which leads to low power generation. To address this problem, a control method based on differential game theory is proposed in this paper. The potential energy and kinetic energy of sea water are converted into electric energy through the water-turbine generator set. In the process of exploitation and utilization of tidal resource, three kinds of development methods have been proposed. Considering the characteristics of intermittency and fluidity of the sea tide, the virtual opponent is introduced. Each generator is controlled by the game of the cost function and the other generators to control the direct current (DC) bus voltage, so as to achieve the Nash equilibrium. Experimental results show that, the proposed method can determine the starting time and the ending time of power generation, the time of gate opening and the storage and drainage process of the reservoir in the time of generation, and has a higher generation capacity.
