This study presents an improved approach to closed-loop scalar control for three-phase induction motor, aiming to enhance the stability and adaptability of the speed control system. The proposed method employs a parallel-structure PI controller, in which the coefficients Kp and Ki are not fixed but are automatically adjusted in real time through a fuzzy logic controller. Simulation results on the MATLAB/Simulink software show that the system achieves higher stability, faster response, and better tracking of the reference speed compared to the conventional PI controller with fixed parameters. This approach enhances the practical applicability of scalar control in induction motor drives, particularly under load and speed variations.

One of the modern and important techniques in the electrical distribution systems is to solve the networks problems service availability, high loss, improve system voltage and reliability, these can be resolved by accommodating small scaled de-centralized generating stations in networks, which is known as Distributed Generation (DG).Distributed generation (DG) units placed at the consumer end will minimize electric power losses, improvexreliabilityyand voltage profile in the system. This paper, presents a method to determine the proper size and location of DG in a distribution system to reduce the losses and improve the voltage stability for different loading conditions. The IEEE 33-Bus system is used to simulate in Power WorldsSimulator (PWS) software and theevoltage profile and losses in the system are analyzed. The Simulated result shows that proper placement and sizing of DG will reduce losses in the system and improve voltage profile within the allowable limit and there by improve the voltage stability.
