Fuzzy Logic Controlled Dual Active Bridge Series Resonant Converter for DC Smart Grid Application

Abstract

Abstract:Over the last few years, smart grids have become a topic of intensive research, development and deployment across the world. This is due to the fact that, through the smart grid, stable and reliable power systems can be achieved. This paper presents a fuzzy logic control for dual active bridge series resonant converters for DC smart grid application. The DC smart grid consists of wind turbine and photovoltaic generators, controllable and DC loads, and power converters. The proposed control method has been applied to the controllable load's and the grid side's dual active bridge series resonant converters for attaining control of the power system. It has been used for management of controllable load's state of charge, DC feeder's voltage stability during the loads and power variations from wind energy and photovoltaic generation and power flow management between the grid side and the DC smart grid. The effectiveness of the proposed DC smart grid operation has been verified by simulation results obtained by using MATLAB ® and PLECS ® cards.
