SIMULATION OF WAVE ENERGY HARVESTING SYSTEM USING MATLAB SIMULINK

Wave is huge energy resource that recognized by the international community as a clean and renewable energy which can be an alternative for fossil fuel. In respond to that, this thesis discussed about the development of a complete simulation model of wave energy harvesting using direct driven linear generator. The objective of this project is to build a simulation model of linear generator and insert wave model to observe the output voltage of the system. A control scheme model is also developed in order to stabilize linear generator output and produce AC voltage that can be feed into the grid. Simulation model of the system is developed by converting equations and parameters involved with the system to Matlab Simulink block. Elements used to develop the control scheme are rectifier, inverter and also filter. Various test had been perform on the simulation model using different input wave to verify the performance of the whole model. The test results reveals that rectifier, inverter and LC filter is capable of altering wave energy harvester output to produce stable voltage that can be feed into the grid.
