Integration of Hybrid Offshore Wind and Wave Energy using PMSG and Linear Generators

To combine the power from the offshore wind energy (OWE) and wave energy conversion (WEC) system, vigorous and suitable generators are required to operate the system and extract energy at the maximum power point (MPP). For the wind turbine, the maximum-power-point-tracking (MPPT) techniques are established via voltage source converter (VSC) to attain power from a permanent magnet synchronous generator (PMSG) based on variable speed. To obtain the maximum power from wave energy the best choice is the use of a linear generator with the VSC. This paper performs a detailed numerical modelling analysis of the linear generator. The combined offshore wind coupled with wave energy is implemented in MATLAB Simulink environment. The simulated results demonstrate the feasibility of the proposed offshore wind-wave energy system.
