The objectives of load frequency control (LFC) are to minimize the transient deviations in these variables (area frequency and tie-line power interchange) and to ensure their steady state errors to be zeros. Since the tieline interfaces give rise to weakly coupled terms between areas, the large-scale power system can be decentralized into small subsystems through treating tie-line signals as di...

This paper aims at investigating the problem of Load Frequency Control (LFC) in interconnected power systems in order to obtain robustness against uncertainties. A design method for a robust controller, based on Quantitative Feedback Theory (QFT), has been presented in this paper. For a two-area power system, the simulation results show that the system response with the proposed QFT controller ...

Abstract: In the present work, we focus on the study of dynamic behavior of an interconnected two-area power system and a scheme for improvement of response for the same. Here, two-area system with one non-reheat thermal units & one reheat thermal units is considered. The frequency and tie-line power deviation of two units are studied using MATLAB-SIMULINK in continuous time domain and also in ...

A combined analysis of multiple terrestrial laser scanner point clouds recorded from different positions requires a geometric registration of these scans. In most applications of terrestrial laser scanning, artificial tie points, which can be recognized automatically by proprietary scanner software, are placed in the scanning area. In this case, the scan positions have to be chosen in a way tha...

Direct measurement of exterior orientation parameters has been a challenge in photogrammetry for many years. Direct sensor orientation using a calibrated GPS/IMU system can potentially eliminate the need for ground control points and aerial triangulation, and consequently, result in a great reduction in the cost and time of aerial photogrammetry. Previous studies have shown that, comparing to c...

Thermodynamic equilibrium computations are usually the most time consuming component in compositional reservoir flow simulation. A Compositional Space Adaptive Tabulation (CSAT) approach has been developed in order to speed up the Equation of State (EoS) computations. The methodology adaptively parameterizes the compositional space using a small number of tie-lines, which are assembled into a t...
