controller design and optimization problems, with more than one objective, are referred as multiple objectives or multiple attributed problems. in this paper, a novel method is proposed for designing optimum pid controller that is called genetic multiple attributed decision making method (gmadm). this method is newer than the previous methods and in this paper some options are considered that h...
voltage stability may be improved by various control functions. in this paper, it is shown that how high side voltage control (hivc) may be employed for this purpose. two test systems, namely a 22- bus and ieee u8-bus systems are used to demonstrate the proposed tuning strategy for hsvc control parameters.
In this paper, design of optimal control for the UPFC controllers including power-flow, DC voltage regulator and generator terminals voltage controller are presented. The controllers were designed based on GA optimization method for linearized modified Phillips Heffron model of SMIB in state space form. For nominal operating condition, the eigen-values of the system were obtained which clearly ...
This article proposed a novel topology of dynamic voltage regulator using transformer and PWM multi-level AC/AC converter. In this paper for finding the best value of duty ratio for switches to minimize the THD, the GA algorithm has been used and THD output voltage is assumed to be fitness function. The proposed voltage regulator employs multi-level AC/AC converter to generate compensation volt...

this paper presents a self-tuning pid (proportional and integral and derivative) controller for regulating terminal voltage synchronous generators. in order to modify the system reponse and to overcome the difficulties of self tuning controllers, a dual rate sampling control system was used. system results demonstrated usfulness of the proposed regulator. the designed controller is simple and c...
This paper shows how a competitive ancillary service market for voltage control/reactive power might operate and what it might look like, given the eminently local nature of the service. An automatic voltage control would dynamically manage the reactive power available in a certain geographic region and a local market in reactive power could then be developed similarly to that proposed for the ...
This paper presents the results of a survey on cluster of rice industries that investigates the effect of voltage sag on the industries feeding from same source. The survey also observed factory operation, products, equipment and processes used in production. In this paper we analyzed an electrical system sensitivity regarding voltage sags. Several proposals are there to analyzing the sensitivi...
It is presented the design and construction of resistive voltage dividers 150 KV class for DC and AC measurements in a high voltage laboratory, using low cost commercial elements.
