Modeling and Analysis Point absorber For Buoy Wave Energy Converter Using Heave Motion

Today, more than 80% of the produced energy in the world comes from fossil fuels. Therefore, the search of new methods is considered in order to use of new source energy. Sea is one of the most important sources of energy. The waves are the main sources of energy that by using technology and modern equipment, it can be converted into needed energy for different purposes. In this paper, according to this fact, the modeling of device is considered that can be used to model the energy of ocean waves into electrical energy for different goals. This device has a cylindrical buoy which uses heave motion in order to produce energy. The simulation of mathematic equations of the device has been done in Matlab Simulink and the results of modeling and analysis, including displacement, velocity, force and power has been considered.
