Abstract

Switched mode power converters are an important component in interfacing renewable energy sources to smart grids and microgrids. The voltage obtained from power conversion is usually full of ripples. In order to minimize the ripple in the output, certain topological developments are made. Increasing the energy storage elements and interleaving them for 180° phase shift reduces the ripple in the circuit. This is made possible by controlling the converters using Type II and III controllers and the results are compared with PID controller. The performance is analyzed and compared in Simulink environment. Transient and steady state analysis is done for better understanding of the system.

Keywords: Interleaved fourth order boost converter, higher order converters, Type II and III controllers, PID controller, smart grid interface, k-factor approach

8.1 Introduction

In the evolving age of cyber physical systems, several technologies and algorithms have been developed for automation where human effort is minimum. One example of such system is the smart grids. Smart grids are evolving faster to accommodate the growing energy demands. These grids are well-equipped with systems which can select the power sources considering various real time loses ...
