Pulsed power loads such as electromagnetic guns, electron lasers, high-power radars, electromagnetic launch and recovery systems can cause significant stress on aircraft electric power systems. In this paper, the performance characteristics of a fully integrated advanced aircraft electric power system (AAEPS) with a hybrid fuel cell-battery auxiliary power unit and connected pulsed power loads are...
Growing complexity and nonlinear structure of modern aircraft electric power systems with extensive nonlinear loading made available state-space averaging models inadequate for accurate analysis and characterization of such systems. In this paper, the Generalized State-Space Averaging (GSSA) model recently developed by the authors is applied for the modeling, control, and characterization of high...
The K-Means clustering is one of the most popular and influential algorithms in data categorizing methods. K-Means simple and straightforward formulation made it a widely acceptable method in many fields and applications. This simplicity comes with some prices such user defined number of clusters, uniformly sized clusters and different final clusters as of being sensitive to initial centroids. K-means...
This paper presents a new method to asses voltage stability of unbalanced distribution systems with wind turbine generation systems (WTGSs). In the voltage tracing process, the Lagrange linear and quadratic interpolations have been applied to predict voltage magnitudes and phase angles. The predicted solutions are then corrected using the unbalanced three-phase forward/backward power flow solver....
Power-system calculations and studies are considering an essential issue to study the behavior of the distributed power system networks. In this paper development GUI software is used for stability studies of distribution power networks with distributed energy resources. The software is based on multi- tier architecture. The multi-tier architecture consists of different layers which perform different...
Voltage stability has been well investigated for the traditional power system using bifurcation analysis: saddle-node bifurcation (SNB) and hopf bifurcation (HB). This paper studies the impacts of distributed generators (DGs) on the voltage stability of power system. The bifurcations analysis is applied on the steady state three-phase load-flow Jacobian-matrix of unbalanced distribution system. The...
This article presents a comprehensive set of Generalized State Space Averaging (GSSA) models for the generation of non-linear control signals in the multi-converter system of an Advanced Aircraft Electric Power System (AAEPS). Due to the switching nature and variation in loading configuration in the aircraft system under study, the pulse-width modulation (PWM) control signals demonstrate inherent...
In this article a comprehensive dynamic bifurcation analysis of the Variable Speed Constant Frequency (VSCF) Advanced Aircraft Electric Power System (AAEPS) corresponding to Boeing 767 is performed. A complete set of state space differential equations are developed to verify the aircraft electric power system stabilities under various loading configurations. In order to investigate the system's sustainability...
