The research shows that installing a spiral spring-flywheel PTO can enhance the stability of energy acquisition and increase the power generation bandwidth of the WEC. Under regular wave conditions, the standard deviation of power is positively correlated with the spring stiffness and negatively correlated with the flywheel moment of inertia, with this phenomenon being more pronounced near the resonance period., authors=Cao Feifei^1~3, Xu Yingzhou¹, Jiang Xiaoqiang¹, Zhang Shuo¹, Zhang Chongwei⁴, Shi Hongda^1~3, authorsList=Cao Feifei, Xu Yingzhou, Jiang Xiaoqiang, Zhang Shuo, Zhang Chongwei, Shi Hongda, authorCompany=1.
