Mohammad Reza Yousefi; Amin Dehghani; Ali Asghar Amini

Articles in Press, Accepted Manuscript, Available Online from 20 November 2021

  In this paper, we propose a new multi-resolution wavelet based mesh free method for numerical analysis of electromagnetic field problems. In problems with variable object geometries or mechanical movements, the mesh free methods yield more accurate simulation results compared to the finite element approach ...  Read More

Optimal Capacitor Placement to Improve the Performance of the Electrical Power Distribution System Using Genetic Algorithm

Mohammad Hossein Kafi; Mehdi Mahdavian; Ali Asghar Amini; Ghazanfar Shahgholian; Majid Dehghani

Volume 11, Issue 03 , September 2022, , Pages 111-117

  The purpose using capacitors in distribution networks is to reduce the total losses of the network. Capacitors help regulate the power factor and voltage in the electrical distribution system, and can be controlled remotely, in and out of the system. Capacitor placement depends on the objective function, ...  Read More

Improvement Damping Power System Oscillations by Using Static Synchronous Series Compensator

Majid Dehghani; Mehdi Mahdavian; Ali Asghar Amini

Volume 10, Issue 04 , November 2021, , Pages 197-202

  From a steady state point of view, FACTS devices operate by increasing or decreasing voltage, supplying or absorbing reactive power, and controlling the impedance of a series of transmission lines or phase angles. There are two types of power fluctuation damping controllers in power systems: power system ...  Read More
