摘要：
In this paper, the virtual synchronous generator (VSG) control is introduced for improving the electrical energy stability of the direct-drive wave power generation system. A simulation model of permanent magnet linear generator (PMLG) is built in ANSYS Maxwell and the output electric energy is controlled by PWM rectification. The instantaneous fluctuation of active power is reduced by battery energy storage system (BESS). The mechanism and electromagnetism characteristics of inertial support provided by traditional synchronous generators are studied to establish the mathematical model of VSG control. The VSG strategy can make the inverters increase the inertia and damping like synchronous generators, thereby providing inertial support and participating in frequency adjustment. The correctness and effectiveness of the VSG control strategy in wave power generation system are verified by simulation results.
