Abstract Reliability and active power loss are two fundamental parameters in the design and planning of distribution systems that have always attracted the attention of power distribution systems designers and engineers. The improvement of reliability and the reduction of power loss are investigated as the primary objective functions and voltage profile as the secondary objective function. A me...

The main purpose of this paper is to design an optimal PID controller for frequency stabilization in an isolated wind-diesel power system. Optimal tuning of PID controller, formulated as an optimization problem and solved using Krill Herd (KH) algorithm. In order to prove the performance of proposed method, simulation carried out in four cases, step change in load of diesel side, step change in...

Green cloud computing is a modern approach that provides pay-per-use information and communication technologies with minimal carbon footprint. Cloud enables users to access resources without the need for local servers or personal devices operate applications. It allows businesses developers infrastructure hardware conveniently. Consequently, this results in growing demand data centers. becomes ...

In this paper, a new sensorless model reference adaptive method is used for direct control of active and reactive power of the doubly fed induction generator (DFIG). In order to estimate the rotor speed, a high frequency signal injection scheme is implemented. In this study, to improve the accuracy of speed estimation, two methods are suggested. First, the coefficients of proportional-integral ...

The behavior of beam-to-column connections significantly influences the stability, strength, and stiffness steel structures. This is particularly important in extreme non-elastic responses, i.e., earthquakes, sudden column removal, as fluctuation strength affects both supply demand. Accordingly, it essential to accurately estimate analysis design procedures for Beginning with state-of-the-art, ...

The South Georgia region supports a large biomass of krill that is subject to high interannual variability. The apparent lack of a locally self-maintaining krill population at South Georgia means that understanding the mechanism underlying these observed population characteristics is essential to successful ecosystem-based management of krill fishery in the region. Krill acoustic-density data f...
