Design of integral terminal sliding mode controller for the hybrid AC/DC microgrids involving renewables and energy storage systems

Project Code :TEPGCS33

Objective

Main objective of this project is to maintain constant DC and AC bus voltage during islanding and grid-connected mode.

Abstract

In this project, the design of a centralized nonlinear controller based on the integral terminal and fast integral terminal sliding mode control for hybrid AC/DC micro-grid is proposed, involving renewable distributed generator as a primary source, Fuel Cell (FC) as a secondary source, and battery-ultra-capacitor as Hybrid Energy Storage System (HESS). 

At first, the detailed mathematical model of the hybrid AC/DC micro-grid is established. Then, the controller is designed with the main objective to ensure the constant DC and AC bus voltage during islanding and grid-connected mode. During grid-connected mode, the controller is capable of providing frequency support to the utility grid. After that, the asymptotic stability of the hybrid AC/DC micro-grid is proved using Lyapunov stability criteria. 

Then, the performance and robustness of the proposed control approach are tested by simulating it on MATLAB/Simulink, and the results are compared with sliding mode controller and Lyapunov redesign.
