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

Abstract

To combine the power from an offshore wind energy (OWE) and wave energy conversion (WEC) system, a vigorous and suitable generators are required to run the system and extract energy frequently at the maximum power point (MPP). The offshore wind energy maximum-powerpoint-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 get maximum power from wave energy the best choice is the linear generator with the VSC. A detailed numerical modelling analysis of the linear generator is carried out. The combined offshore wind coupled with wave energy is implemented in MATLAB Simulink environment. Furthermore, the final simulated results of offshore windwave energy system is analyzed and compared with each other.
