Abstract
This study includes a multilevel cascaded inverter along with a control strategy. This proposed control scheme directs the inverter to support the grid under three - phase balanced voltage sags and during one or two - phase faults. Control of voltage between grid and Distributed Generation (DG) system is a challenging subject. Integrating DG with the grid is the fundamental element of this study which depends on grid codes prescribed by the transmission system operators. These electrical dispatching standards endow smartness and flexibility of DGs. The proposed system is designed using MATLAB/Simulink tool. Simulated results show the feasibility of the proposed control scheme.
