This device transforms the mechanical energy of a moving body into electrical energy. This paper describes the model of an innovative PTO based on independently activated double-acting hydraulic cylinders array. The model has been developed using a simulation tool, based on a port-based approach to model hydraulics systems. The components and subsystems used in the model have been parameterized as real components and their values experimentally obtained from an existing prototype. In fact, the model takes into account most of the hydraulic losses of each component. The simulations show the flexibility to apply different restraining torques to the input movement depending on the geometrical configuration and the hydraulic cylinders on duty, easily modified by a control law. The combination of these two actions allows suitable flexibility to adapt the device to different sea states whilst optimizing the energy extraction. The model has been validated using a real test bench showing good correlations between simulation and experimental tests385318991enginfo:eu-repo/semantics/openAccessjournal article10.3390/en8032230hydraulic power take-offPTOPTO Modelwave energy conversionWECPTO simulationhydraulic power take-offPTOPTO Modelwave energy conversionWECPTO simulationRenewable Energy, Sustainability and the EnvironmentFuel TechnologyEnergy Engineering and Power TechnologyEnergy (miscellaneous)Control and OptimizationElectrical and Electronic EngineeringSDG 7 - Affordable and Clean EnergyFunding InfoSpanish Government PS-440000-2008-1, Regional Government of the Basque Country IT719-13, UPV/EHU UFI11/28Spanish Government PS-440000-2008-1, Regional Government of the Basque Country IT719-13, UPV/EHU UFI11/28http://www.scopus.com/inward/record.url?scp=84928616788&partnerID=8YFLogxK
