Stability analysis of the hydraulic wind energy transfers model

Gearless hydraulic wind power transfers are considered noble candidates for wind energy harvesting. In this method, high-pressure hydraulics is utilized to collect the energy of multiple wind turbines and transfer it to a central generation unit. The mathematical model of the gearless wind energy transfer system is described in the previous literature. This paper determines the stability of the mathematical model by careful assessment of the state-space representations of the model of the hydraulic system. The existence of limit cycle is investigated for the nonlinear model and the equilibrium point of the system is calculated. The results show that both linear and nonlinear models are stable.
