This paper presents a simple simulation approach to study static voltage stability in power systems. Symbolic and Optimization toolboxes in MATLAB are used to simulate load flow, continuation power flow and optimization techniques to easily assess and understand static voltage stability of power systems. P-V curves are constructed to calculate loadability margins. These margins are verified wit...

In this communication, hexapod tripod gaits for straightline motion and crab walking are derived. Mathematical relations that express the stability margin, the stride length, and the duty factor are formulated for straight-line motion and for crab walking, respectively. The derived results provide tripod gaits of the hexapod for walking with a prescribed stability margin either over perfect ter...

Energy methods have shown promise as measures for quantifying the vulnerability of power systems to problems of voltage instability and collapse. However, to make such measures more useful as a security assessment tool in an operational environment, it is important to provide physical interpretations of the quantitative measure. This paper will demonstrate that for certain basic load models, th...

Department of Mathematics Sathyabama University, Chennai – 119 [email protected] Abstract This paper deals with the Distributed Generation (DG) capacity of the electrical power system. DG capacity is formulated as a Mixed Integer Programming (MIP) problem with respect to various operating constraints in power generation. The objective of this model is to minimize the real power loss by ...

abstract marketing element’s contrastive behaviors toward price risk had considerable effect on marketing margin in a way that transferring increase in price to final consumer, reduces purchasing power and so consumption amounts of consumers. present study evaluated effective parameters on marketing margin in 2 level of ranch-processing and processing- retail of beef and lamb with consideration...
