Development Of An Integrated Generator Power Take-Off Strategy Using Model Predictive Control (MPC) For Ocean Wave-Energy Conversion
Model Predictive Control (MPC) has previously been investigated on ocean wave energy converters (WEC) to improve the amount of power captured, while respecting the system constraints. Previous research done in the same area, focused on building a control scheme by using the knowledge of the past & current states of the system and predicting the future states of the system based on which the control action was taken for the power-take-off (PTO) to maximize power capture. This was done by maximizing the product offorce and velocity and at the same time, staying under the permissible limits of both force and velocity (constraints). Our research attempts investigate if an integrated approach for power maximization is possible by trying to modify the way power maximization is done. This is made possible by integrating a state-space generator model with a state-space WEC model. This combined generator-WEC model is then used with an MPCcontroller. So rather than having PTO-force as the input for the wave energy converter, dq reference frame voltages are used as inputs and the product of voltages and currents for the d and q axes (i.e. the electrical power) is maximized.
