Medium voltage cascaded H-Bridge motor drives (MV-CHBMD) are popular with renewable applications because of their scalability, reliability, and modularity. The MV-CBHMDs are used in different medium voltage applications and significantly affect grid flexibility, performance, and efficiency. Even with the famous use of MV-CHBMD, the provided simulation models need to be more detailed to cover grid connection dynamic investigations. This study provides a dynamic design of MV-CHBMD, connected with the power grid source and induction motor (IM) with load, which provides a compliance large-scale analysis for the dynamic act of the power grid system. The proposed model of dynamic MV-CHBMD is suitable for power system studies. The model provides an analytical analysis of the grid connection with the cascaded H-bridge motor driver (CHBMD) and IM on the load side of the driver. It accurately represents the dynamic of the total system under different disturbances. The main factors affected during any perturbation are variable frequency and voltage, which are deeply considered in the proposed model. A simulation analysis verifies the model's accuracy, reliability, and effectivity. The mode sensitivity analysis depends on the impact of the variable parameters on the system acting and responding. The proposed model is easily insertable in the extensive grid-simulating system, which provides more accurate results in power grid dynamic studies.
