Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

This paper presents a method for determination of the optimal placement and sizing of FACTS device. The objective considered is to maximize the available transfer capability (ATC) of heavy transaction zones. Generally, ATC calculation is recursive and consequently time consuming. In this paper the power transfer distribution factor (PTDF) is used for fast calculation of the ATC. The method is modified to include losses and subsequently, the FACTS placement problem is solved using a genetic algorithm to obtain the least loss at the maximum ATC. For the purpose of comparison the ATC is also calculated using the repeated power flows method. This paper shows that the PTDF method is both computational more efficient and provides a sufficient degree of solution accuracy.
