Design and Analysis of a PID Controller for an AVR System Using MOL Optimization Algorithm and Its Comparison with Other Intelligent Algorithms

摘要

Some of the important Automatic Voltage Regulator (AVR) system tasks in power network are generator output voltage regulation, distribution, and reactive power regulation of generators. However, the AVR system without controller does not have a suitable performance. Therefore the Proportional Integral Derivative (PID) controller is used to improve AVR system performance. There are different methods in order to determine PID controller coefficients, by which in this paper a new method ca lled MOL algorithm is getting used. To demonstrate a better performance of MOL algorithm a comparison has been done between this method and other methods like Artificial Bee Colony (ABC), Particle Swarm Optimization (PSO), and Differential Evolution (DE).
