SUPER TWISTING SLIDING MODE CONTROL BASED VOLTAGE SOURCE CONVERTER FOR POWER MANAGEMENT OF HYBRID ENERGY SYSTEM

This paper proposes a method for controlling and coordinating energy management in hybrid microgrids, whichis a complex task due to the integration of different power generation resources. To efficiently integrate renewableenergy sources (RES) like solar, wind, and battery storage, multiple power converters are required. The overallperformance of hybrid microgrid power system network heavily depends on the operation of these powerconverters. Voltage Source Converters (VSCs) play a crucial role in optimizing power flow within the microgridby providing advanced control capabilities such as voltage regulation, reactive power control, and dynamicresponse to system changes, enhancing efficiency and reliability of system. In this paper, a Super Twisting SlidingMode Control (STSMC) strategy is developed to operate single-phase VSC at the load side. The systemincorporates battery support alongside solar and wind power generation to meet load demand and improve powerquality. The performance of proposed STSMC-based hybrid microgrid is evaluated under two scenarios: steadyload connected to variable solar and wind energies, and dynamic load connected to constant PV and wind power.This project is implemented in 2024a Matlab Simulink.
