An Improved Neural Network Based on Parasitism – Predation Algorithm for an Automatic Voltage Regulator

Abstract

The parasitism – predation algorithm (PPA) is an optimization method that duplicates the interaction of mutualism between predators (cats), parasites (cuckoos), and hosts (crows). The study employs a combination of the PPA methods using the cascade-forward backpropagation neural network. This hybrid method employs an automatic voltage regulator (AVR) on a single machine system, with the performance measurement focusing on speed and the rotor angle. The performance of the proposed method is compared with the feed-forward backpropagation neural network (FFBNN), cascade-forward backpropagation neural network (CFBNN), Elman recurrent neural network (E-RNN), focused time-delay neural network (FTDNN), and distributed time-delay neural network (DTDNN). The results show that the proposed method exhibits the best speed and rotor angle performance. The PPA-CFBNN method has the ability to reduce the overshoot of the speed by 1.569% and the rotor angle by 0.724%.

“…Power system control is a key role in fulfilling electricity needs. In addition, the increased complexity of the load is also a concern [1]. Direct current (DC) motors are included in the category of types of motors that are most widely used in industrial environments, household appliances to as supporting devices for electronic instrument systems [2].…”

Cooperation search algorithm for tuning automatic voltage regulator system

“…An alternating current (AC) generator is equipment that functions to convert mechanical energy (motion) into electrical energy (electricity) by means of magnetic field induction. This energy change occurs due to a change in the magnetic field in the armature coil (where the voltage is generated in the generator) [5], [6]. It is called a synchronous generator because the number of rotations of the rotor is equal to the number of turns of the magnetic field in the stator.…”
