In our work a Compact Sized Microstrip Patch Antenna has been designed using Sierpinski Triangle fractal geometry. Genetic algorithm is applied for optimization of the patch dimensions. Triangular slots have been incorporated in the ground plane which have been increased in subsequent iteration. A triangular shaped patch is placed on top of Roger 4350 substrate which has an electrical permittivity...
This paper presents a novel particle swarm optimizer combined with roulette selection operator to solve the economic load dispatch (ELD) problem of thermal generators of a power system. Several factors such as quadratic cost functions with valve point loading, transmission loss, generator ramp rate limits and prohibited operating zone are considered in the computation models. This new approach provides...
This article has surveyed some of the most important techniques used to generate the reference current for the shunt-type APF (active power filter). The GA-based approach is discussed in detail. Zero-crossing detection of one of the source voltages is sufficient, and the PLL may be removed. An ANN-based PI controller is added for faster buildup of the voltage across the capacitor. Faster control of...
