Adaptive Radiotherapy (ART) is a technique which minimizes the dosimetric impact of anatomical changes that may occur during treatment. One of the milestones of ART is deformable image registration (DIR) between original planning images and images acquired during treatment. The aim of this study is to propose a method to evaluate the performances and validate the clinical use of a “Demons” intensity-based...
Cascading Failure and Blackout Event is one of the major concerns to all in the Power System industry. Recent literature mainly focused on predicting the occurrence of this catastrophic event and suggestions on ways to curtail the spread of Cascading Failure. No research, to our knowledge, as focused on preventing Cascading Failure without the use of high cost precautionary steps. This work utilizes...
A Transient Stability Analysis of a low inertia microgrid system is presented in this paper. The analysis is performed on experimental data collected for different case scenarios of grid disturbances. The test bed consists of a reconfigurable 100kW MicroGrid system with more than 10 rotating generators, PV, and Wind penetration capabilities. Both islanded and non-islanded situations are considered...
In this work, a technique based on an adaptive Multi-Agent System algorithm is implemented to solve the complex problem of cascading failure events which lead to total blackout. This method proposes a solution to a variant of cascading failure events and is unique as previous literature focuses on identifying the possibility of occurrence of the cascading failures and then mitigates the failures....
There have been numerous simulation works done on Grid Restoration using Multi-Agent System but almost no experimental work to ascertain the duplicity of these simulation results. This work aims to experimentally perform distributed restoration of a smart power grid system. The concept used in this research is based on the distributed and intelligent multi-agent system technology where multiple smart...
The accuracy of measurements from a rotary encoder is of high importance and the level of accuracy desired will depend on the nature of the application in which the encoder is used. Due to the various errors in the rotary encoder measurement during real-time usage, this work has designed a LabVIEW program that exempts erroneous readings that are not within the chosen range, forms an array of readings...
In this Work, we investigate the use of two-way communication to perform distributed restoration of smart power grid distribution systems. The concept used in this research is based on the distributed and intelligent multi-agent system technology where multiple smart entities are geographically spread and if equipped with communication capability these entities are able to reach goals or solutions...
A Multi-Agent System (MAS) for Smart Grid control is developed as part of the West Virginia Super Circuit (WVSC) Smart Grid Demonstration project. Both software and hardware deployment of the technology is being carried out on an Analog Power Simulator upgraded and automated to meet the Smart Grid requirements. The Multi-Agent System which is developed is based on mimicking the Human Immune System...
In this paper, a new technique in designing MultiAgent System (MAS) for power system reconfiguration and restoration is proposed. The designed MAS system is based on mimicking the human immune system behavior. The Immune system is a natural intelligent MAS where different components interact to heal the body. Similarly, the proposed multi-agent system is designed to detect and isolate faults, and...
In this paper, an automation and self healing scheme based on an artificial immune system (AIS) is developed for power systems. The AIS works like a protective layer that strives to eliminate the damages and anomalies to the system while creating an immunity-like for the power systems by remembering the actions taken against a specific anomaly or damage.
In this paper, a decentralized automatic generation control design based on an artificial immune system algorithm is proposed. Using the concept of immune cell-pathogen interactions the power system is assimilated to a human body which strives to fight and eliminate damages and anomalies. The immune based controller takes smart actions that (1) assure compliance with NERC's control performance standards,...
