In this paper, a proposed efficient solution for an important power quality problem focused on harmonic distortion in the source current is introduced by using Shunt Active Power Filter (SAPF) controlled sinusoidal control strategy which based instantaneous active and reactive theory (Sinusoidal PQ-theory). As part of controller, there PI-Controller enhances APF controller performance when tuni...

DC microgrids have gained a lot of interest recently due to increasing dc loads such as electric vehicles and the penetration renewable energy sources (RESs). However, face challenges concerning bus voltage fluctuations, which severely impact system stability when subjected uncertainties load RESs. This paper focuses on maintaining DC-bus through control for islanded microgrid using concept cas...

This paper presents an optimal design of a Static Var Compensator (SVC) for damping improvement of a Single Machine Infinite Bus (SMIB) system. In this study, SVC is installed to improve the angle stability of a synchronous generator. A new computational intelligence approach using Mutated Particle Swarm Optimization (MPSO) technique is implemented. The study involves the optimization of the pr...

The objective of this work is to design and implement a closed loop system for induction motor starting at rated current. Thyristorized AC voltage regulator is used as the starting equipment and motor current regulation is carried out using an optimally tuned Proportional-Integral (PI) controller. Since, AC voltage controller fed starting of induction motor is a non-linear process, identificati...

Ant Colony Optimization (ACO) used to tune the Proportional and Integral (PI) controller for Single Ended Primary Inductance Converter (SEPIC) is discussed in this paper. The SEPIC is based on DC to DC converter to maintain the constant output voltage but varying input voltage. PI controller maintains a constant output of the converter, without changing sign. MATLAB simulation designing is deve...

Due to the continuous change in load, the frequency and tie-line power of control areas get disturbed from their scheduled value which is undesirable. Automatic Generation Control (AGC) is an essential mechanism in electric power systems which balance generated power and demand in each control area in order to maintain the system frequency at nominal value and tie-line power at its scheduled va...
