As the power grid is continuously expanding, the increased amount of loading and the corresponding amount of generation is causing the grid to become more and more complex. The addition of intelligent devices for control and communications is also making the grid more vulnerable to failures. The addition of distributed renewable energy sources can potentially alleviate some of the stress on the grid,...
This paper demonstrates a prototype for a smart street-lighting system, in which a number of DC street lights are powered by a photovoltaic (PV) source. A battery is added to store the excess energy of the solar panel, which can later be retrieved at night time, or whenever the sunlight is being obstructed by clouds or other forms of shading. A charge controller is used to protect the battery from...
Distributed Generation (DG) sources such as solar and wind power sources are gaining an increased popularity due to the various advantages they provide over the traditional fossilfuel-based power generation sources. However, their effects on the system operation, while expected to be positive, are not yet fully understood. In this paper, we study the effect of adding DG sources to the grid on the...
Islanding occurs when distributed resources continue to power even though electrical power from the utility grid is no longer present. Islanding can be harmful for utility workers, who may not realize that this part is still powered. For the reason of safety hazards and equipment damage due to lack of utility control on voltage and frequency in the island, distributed resources must detect an island...
Load flow analysis is the backbone of the power system studies and design, and through it the voltage magnitude and phase angle at each bus and the complex power flowing in each transmission line can be obtained. In this paper, we use the load-flow to perform a sensitivity analysis of the IEEE 30 bus system. We find the maximum complex power flowing in each transmission line in case of no fault and...
The Immersive Audio Environment (IAE) was designed to provide an effective military training facility. It's efficacy at synthesizing sounds from desired directions and also the ability to synthesize moving sounds has been previously reported. This paper discusses the addition of a tracking system to evaluate subject training performance. Numerous tracking systems have been developed for tracking in...
Regularization is an important part of adaptive filter design. Traditionally, the regularization parameter has been empirically selected, as there has not been a lot of work in the literature for determining an optimal method for finding its best value. In this work, we propose an adaptive method for finding the regularization parameter in the normalized least-mean-square (NLMS) algorithm. Furthermore,...
