Influence functions for a hysteretic deformable mirror with a high-density 2D array of actuators
We present modeling and analysis of a hysteretic deformable mirror where the
facesheet interacts with a continuous layer of piezoelectric material that can
be actuated distributively by a matrix of electrodes through multiplexing.
Moreover, a method for calculating the actuator influence functions is
described considering the particular arrangement of electrodes. The results are
presented in a semi-analytical model to describe the facesheet's deformation
caused by a high density array of actuators, and validated in a simulation. The
proposed modeling of an interconnection layout of electrodes is used to
determine the optimal pressures the actuators have to exert for achieving a
desired surface deformation
Revenue Optimization for the Ocean Grazer Wave Energy Converter through Storage Utilization
Increased penetration of renewable energy generation motivates a change of paradigm in the way power systems are structured and operated, as advocated by the smart grid concept. Accordingly, in this paper we investigate the lossless storage capabilities of the Ocean Grazer wave energy converter (WEC), which could facilitate the aforementioned paradigm shift. This specific WEC exhibits both adaptability with respect to the incoming waves and significant lossless storage capabilities. We propose a model predictive control (MPC) strategy based on a lumped dynamical model in order to mitigate power imbalances in the power grid and maximize the revenue of the WEC. Furthermore, we illustrate that the proposed strategy exploits the WEC energy storage capabilities and we show the economic benefits it brings. Lastly, the proposed strategy is compared with a heuristic approach and a setting without storage
