Distributed Flexible AC Transmission System (D-FACTS) devices offer many potential benefits to power system operations. This paper presents a novel strategy for the application of D-FACTS devices in controlling system voltage. The impact of installing D-FACTS devices is examined by studying the sensitivities of voltage magnitude with respect to line impedance. Sensitivities enable us to determine...
The concept of Distributed Flexible AC Transmission Systems (D-FACTS) was introduced in order to provide a cost-effective solution for power flow control. Distributed Static Series Compensator (DSSC) device can be clamped on to existing power lines and be operated so as to control the impedance of the conductor - realizing the first in a family of D-FACTS devices. Determining the location and amount...
The concept of Distributed FACTS (D-FACTS) has been proposed as an alternative approach to realizing cost-effective power flow control. When technology of D-FACTS is being further advanced, there is an increasing interest to find the optimal locations of these devices. The best location and size of D-FACTS is necessary for optimal control of the power flow in a large meshed network. Being a distributed...
The surface of silicondioxide/silicon structures is charged with the tip of a cantilever in contact mode by application of a voltage. Then, the surface potential is measured contactless using the Kelvin option of an atomic force microscope. On the position of the charged domain a potential difference in relation to the uncharged region is found. It turns out that the height and the width of this potential...
This paper presents a hybrid technique combining Evolutionary Strategy(ES) with Biogeography Based Optimization (BBO/ES) algorithm to solve economic load dispatch problems of thermal plants considering equality and inequality constraints, transmission losses and valve point loading. Biogeography is a recently developed heuristic algorithm which has shown impressive performance on many well known benchmarks...
Current work on bipartite graph-based algorithm for protein tertiary structure matching shows that the algorithm demands heavy computation and extensive processing time during graph preparation and matching. In this work, we deployed multithreading approach using OpenMP to enhance the performance of the algorithm. The experiment on dual quad core machines shows that the speedup is 4.9 on 8 threads...
