Abstract—This paper represents performance of particle swarm optimisation (PSO) algorithm based integral (I) controller and proportional-integral controller (PI) for interconnected hydro-thermal automatic generation control (AGC) with generation rate constraint (GRC) and Thyristor controlled phase shifter (TCPS) in series with tie line. The control strategy of TCPS provides active control of sy...

This article presents a Particle Swarm Optimization with timevarying acceleration coefficients (TVAC-PSO) technique for the design of Integral (I) controller for the Load Frequency Control (LFC) system. The LFC modeling is carried out for Multi-area interconnected power systems (MAIPS). The power system comprises non-reheat thermal unit in each control area. The controller gains have been optim...

In this work I have tried to apply effective dedicated online control systems to two equal power systems connected by a long distance tie-line. When large interconnected systems are linked electrically to others by means of tie-lines, the power transfers between them are usually decided by mutual agreement and the power is controlled by regulators. Other side it is a desired feature to achieve ...

Compared with traditional manned airborne photogrammetry, unmanned aerial vehicle remote sensing (UAVRS) has the advantages of lower cost and higher flexibility in data acquisition. It has, therefore, found various applications in fields such as three-dimensional (3D) mapping, emergency management, and so on. However, due to the instability of the UAVRS platforms and the low accuracy of the onb...

Arrays of subwavelength dipole bow-tie apertures are designed and characterized at terahertz frequencies. For an incident terahertz field perpendicular to the longer axis of the bow tie, a strong resonance enhancement, line narrowing, and a nonmonotonic frequency shift were observed with increasing length of the tapered bow-tie arms. Such characteristic behaviors primarily originate from locali...

Phase separation of biomolecules gives rise to membraneless organelles that contribute the spatiotemporal organization cell. In most cases, such biomolecular condensates contain multiple components, but manner in which interactions between components control stability have remained challenging elucidate. Here, we develop an approach determine tie-line gradients ternary phase-separation systems ...

This paper describes some approaches towards an automation in architectural photogrammetry using digital image processing. We present techniques for semi-automatic 3D measurement and the application of digital image analysis to support the extraction of facade primitives. The proposed semi-automatic 3D measurement is used for the determination of tie points for the orientation and the interacti...

In this study, the separation of formic acid from aqueous solutions was investigated. Liquid-liquid equilibrium (LLE) data including tie-lines was reported for water + formic acid + 2-methylpropyl ethanoate ternary mixture at (293.15 to 323.15) K and atmospheric pressure. The system shows type-I phase behavior based on Treybal’s classification because only one partially miscible binary mixture ...

This paper presents the MATLAB simulink dynamic model of the load frequency control (LFC) of a realistic two area power system having diverse sources of power generation. The DC link is used in parallel with AC tie line for the interconnection of power system. The power system simulation is done using MATLAB simulink and control problem is solved using MATLAB programming. An optimal output feed...

Image-to-image registration requires identification of common points in both images (irnage tie-points: ITPs). Here. we describe software implementing an automated, area-based technique for identifying ITPs. The ITP software was designed to follow two strategies: ( I ) capitalize on human knowledge and patternrecognition strengths, and (2) favour robustness in many situations over optimal perfo...
