The novel MegaRoller technology is based on multiple innovations, including modular PTO design, twin drive train, intelligent cylinders, electric central unit, wave-by-wave prediction, wave-by-wave damping, efficient energy storage control, and supervisor controller. The modular structure allows the modules to be exchanged and adjusted for WaveRoller WEC according to varying wave resource, ambient conditions, and customer requirements. The twin drive train arrangement makes it possible to utilize two PTOs with a single panel and increase the rated power to 1MW. The electric central unit allows to connect the two PTO units of the MegaRoller and feed the power to the grid. Different intelligent cylinder concepts were designed to remove pressure spikes from the MegaRoller hydraulic cylinder circuit. A machine-learning algorithm to produce wave-by-wave predictions is integrated in the MegaRoller PTO control systems software to give an input to damping algorithm. The algorithm predictions are used in PTO damping control for optimized power capture. By applying wave-by-wave damping it is possible to capture significantly more energy from the moving panel.
