Voltage regulation is a crucial task for electrical grids in the presence of high penetration levels renewable energies. The generator excitation improves stability power system. An essential tool controlling generators automatic voltage regulator (AVR). It advised to use controller increase reliability an AVR. A survey about different types controllers proposed this paper. Then, novel optimize...

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.

One of the most popular controllers for automatic voltage regulator (AVR) in maintaining level a synchronous generator is fractional-order proportional–integral-derivative (FOPID) controller. Unfortunately, tuning FOPID controller challenging since there are five gains compared to three conventional proportional–integral–derivative (PID) Therefore, this research work presents variant marine pre...
