With the increasing demand for renewable energy in the world, research contributing to the improvement of the technology level of wave power generation is essential. The authors have been developed a wave power generation system using port facilities in inner bays with high energy-consuming cities. In this study, the relationship between the rotational characteristics of a Savonius water turbine and the water particle velocity was quantitatively evaluated under the calm conditions of the inner bay, such as wave motion, flow, and coexistence of wave and current. According to the experimental results, it is found that the relationship between the rotational circumferential speed and the water particle velocity of the water turbine installed in a wave field tends to be different from that in a flow field and is evaluated by different equations. In addition, the relationship between circumferential velocity and the water particle velocity has also been formulated when installed in a wave-current coexistence field.Recorded Presentation from the vICCE (YouTube Link): https://youtu.be/KX0XBFuao48

The mathematical model of grid-connected wave power generation system based on modular multilevel converter (MMC) is deduced with topology structure and the operation principle of the MMC analyzed in this paper. Then the corresponding current decoupling control strategy is obtained in dq coordinates. Simultaneously, averaging voltage control and voltage balancing control are used to control the MMC to solve the imbalance and the ripple of the capacitor voltage of sub-modules. Moreover, the double closed-loop control strategy is used to control the grid-side MMC. Finally, the simulation model of grid-connected wave power generation system based on MMC is built in Matlab/Simulink. The simulation is carried out to verify the effectiveness and feasibility of the proposed control strategy.
