Speed Orientation of combined Induction Motor Renewable Energy System via Firefly Approach

Abstract

This article introduces the layout of a traditional (PI) Proportional Integral controller via (FA) Firefly Approach to adjust the speed of the commonly used motor; (IM) Induction Motor; supplied by (WT) Wind Turbine as a one of renewable energy resources. WT acts as a main mover to a joined (DC) Direct Current source. DC/AC inverter is utilized to obtain a 3 phase system from the product of DC generator. The developed layout process of the speed controller is formed as a time domain optimization task. FA is involved to seek optimum elements of the controller by reducing the suggested objective time function. The attitude of the decided FA has been valued with the attitude of the traditional (ZN) Zeigler Nichols and (PSO) Particle Swarm Optimization to confirm the supreme adequacy of the developed FA in setting the PI controller. Moreover, the attitude of the suggested controller has been valued for the variation of load torque and speed WT. Imitation results prove the better achievement of the tuned PI elements relied on FA compared with tuned PI elements based on PSO and traditional one along a vast scope of working cases.
