With the global energy crisis and environmental pollution intensified, the development of new energy has become the consensus of the world. Among them, ocean, which accounts for 70.8% of the Earth's surface area, contains a wide range and considerable storage of renewable energy. Energy flow density of wave energy is large, which is a low-cost energy source that can provide considerable power through smaller devices. The rational use of marine wave power generation consumes no fuel and resources, does not produce any pollution, less investment and quick return. Therefore, wave power generation has great potential for development. However, there are some problems to be solved urgently in the wave power generation. The wave energy has the characteristics of large amplitude and variable frequency. Therefore, the input power of the wave power generator is generally unstable, discontinuous and abrupt. And facing of changing climate conditions and other factors, wave power generation devices often work in abnormal conditions, which will cause some degree of impact on some devices, also the power quality of the reliability and stability are affected. A single wave power generation system is usually an independent power generation system or directly connected to the offshore power distribution system and is currently the main form of running wave power generation. Directly connected to the offshore power distribution system in the wave power generation system is not enough to cause a significant impact on the voltage and frequency of large systems, but its impact on the voltage, power quality, power electronic devices of the local power distribution network can not be ignored. Through the analysis of wave power generation characteristics, this paper proposes a inverter control strategy based on the principle of virtual synchronous generator (VSG) to introduce the wave power generation system. Because of its similar characteristics of synchronous generators, such as large output impedance, large inertia, power by droop feature distribution, it is suitable for wave energy this low stability, high mutation rate power generation system. Through the introduction of virtual inertia and damping coefficient, it can improve the stability of wave power generation, improve the efficiency of inverter utilization, reduce the cost of system configuration and improve the service life of converter.
