Interlinking Converters approach for the Autonomous Operation of a Hybrid AC/DC Microgrid using Fuzzy logic controller

Abstract

       The Fundamental control strategy power sharing in DC microgrid (DGMG) is Droop control . In the dc droop approach ( DDA) dc voltage cannot act as a global variable ,moreover power sharing accuracy will get effected due the presence of the line resistance ,these two are rendering limitations to DDA . In a way to improve the performance of the dc microgrid operation in hybrid microgrid system (HMGS) with Interlinking Converters(IC's),to the dc grid a small ac ripple with some frequency is applied.. In this paper the performance of the system is analyzed by using advanced controller the Fuzzy Logic Controller. The proposed FUZZY LOGIC CONTROLLER (FLC) increases the speed of the system and the analyzed results are observed in the simulation/MATLAB results.
