Ocean wave energy farms are composed of several wave energy converter devices. The objective of each converter is to capture the potential and kinetic energy in rolling ocean waves and convert them into electricity. An important task in optimizing power delivery from ocean wave energy farms is short term prediction of incoming ocean waves. Accurate predictions enable predictive wave energy converter...
In order to obtain the maximum power absorption of wave power devices, the mean gain factor q for the array and its characteristics are discussed in this paper. Some characteristics about the maximum q are studied through theoretical derivation and numerical examples. Also, the relationship between the maximum q and the properties of the optimum linear arrays of wave power devices are explored through...
Advanced control systems for Wave Energy Converter (WEC) devices require the prediction of the exact time waveforms of ocean waves. In this paper, ocean waves are described as a sum of several plane waves of different frequencies and directions of travel while sensor measurements are assumed to be observed under Gaussian noise. A general expression for the Cramer Rao Bound (CRB) of the estimates is...
Using a linear DC power flow model, the power flow calculation can be determined by the bus susceptance matrix and the voltage angles. In this paper, we consider a power system where the voltage angle measurement at each bus is transmitted to a control center via a wireless communication channel. In order to model unsuccessful transmissions, we derive a two-component Gaussian mixture model to describe...
In this paper, we focus on a performance bound for joint location and velocity estimation in non-coherent MIMO radars with multiple targets, which has not been studied before. Closed-form expressions for the Cramer-Rao bound are provided for a two-target case. We use numerical simulations to validate the Cramer-Rao bounds and use these bounds to study the performance of a non-coherent MIMO radar system...
