This paper presents a configuration of dual output single-phase current source inverter with six-switches for microgrid applications. The inverter is capable of delivering power to two independent set of loads of equal voltages or different voltages at the load end. The control strategy is based on integral sliding mode control (ISMC). The cyber twin model-based test bench is developed to analyze the performance of the inverter. The cyber twin is a virtual model of the physical system to simulate behaviours. The performance of the inverter is analyzed with a cyber twin model and monitored through the remote system. Also, the inverter is analyzed with different voltage conditions.

Due to depletion of fossil fuels and increasing power demand, employing Renewable Energy Sources (RES) in the form of micro-grid has become very essential. However, the reliable operation and control relies on the intermittent nature of RES and maintaining the frequency within the acceptable limit is the challenging task in isolated micro-grid. This paper presents the Automatic Load Frequency Control (ALFC) in an isolated Micro-Grid (MG) with Superconducting Magnetic Energy Storage (SMES) unit using Integral controller, to enhance the stability of the system frequency. The simulation result shows that the dynamic performance of the proposed system is significantly improved while incorporating the SMES Unit. The simulations are carried out in MATLAB – Simulink.
