Objective

The main objective of this project is to control a PV-Wind Based DC Microgrid With Hybrid Energy Storage System by Using Lyapunov Approach and Sliding Mode Controller.

Abstract

This project presents focuses on the control techniques implemented on a PV-wind based standalone DC microgrid with hybrid storage system. An Enhanced Exponential Reaching Law (EERL) based sliding mode control (SMC) is applied for extraction of maximum power in a Permanent Magnet Synchronous Generator (PMSG) based wind energy system. This reaching law-based SMC tracks current reference from the optimum torque MPPT algorithm during different wind speeds and load variations and has a good dynamic response. A combination of battery and supercapacitor is used as the hybrid storage system for providing reliable and continuous power to the load. The supercapacitor absorbs the transient components during disturbances and helps in improving the life of battery. A control method based on the Lyapunov function, which can ensure global asymptotic stability is implemented for the bidirectional converter of battery and supercapacitor. The proposed method maintains the DC link voltage constant during solar, wind and load variations. A detailed analysis of the two control laws is presented. The simulation results can be evaluated by using Matlab/Simulink Software.

Keywords: Battery, DC microgrid, Lyapunov control, photovoltaic, sliding mode control, supercapacitor, wind energy conversion system.
