A fast and accurate state space model of a multiple body wave energy converter (WEC) is developed in this paper. The purpose of this model is to expedite the development of the advanced controls critical to improving WEC performance. Although it possible to directly couple controller code with some - but not all - high resolution time domain simulation(More)
This study presents an advanced control scheme capable of significantly increasing power production from wave energy conversion (WEC) systems. This control scheme uses a reactive power approach built upon a Model Predictive Control (MPC) framework and is capable of optimizing power capture while also respecting machine constraints (e.g. velocity, maximum(More)
This study uses the open-source wave energy converter simulator (WEC-Sim) code to model the Columbia Power Technologies SeaRay 1:7 scale WEC. WEC-Sim is intended to run quickly on standard desktop equipment and provide a very gentle learning curve for WEC modeling. This paper focuses on the linear implementation of WEC-Sim as that requires the least(More)
Sandia National Laboratories (SNL) and National Renewable Energy Laboratory (NREL) have collaborated to develop the open-source Wave Energy Converter (WEC) modeling tool WEC-Sim, capable of running on a standard personal computer. Its main function is to simulate WECs of arbitrary geometry subject to operational waves; both regular and irregular waves.(More)
