Voltage source converter (VSC) - based high voltage DC (HVDC) transmission is viewed as the eventual fate of offshore power transmission. This paper goes for giving a solid VSC-HVDC transmission system design between offshore wind ranches and inland grids. In this paper, an extensive limit, low-speed flywheel energy storage system (FESS) in light of a squirrel cage inductance machine is connected in parallel with the VSC-HVDC at the grid side converter. The FESS is committed for surge power control (because of power flow unevenness amid fault) retention rather than being dispersed as resistive losses. Since the length of these surges is moderately little, it has been demonstrated that the flywheel can adequately relieve this issue. In this FESS converter model existed by using PI controllers in which will get good response of power leveling operation and under fault conditions of the systems. And FESS offshore wind farms using proposed controller Fuzzy logic controller. It helps for the system improves a power levels, stability of the systems for under normal and abnormal operations compared to PI controller. HVDC system is simulated utilizing MATLAB/Simulink amid ordinary and fault conditions.
