In this paper, the implementation of virtual inertia in a dual two-level voltage source inverter (DTL VSI) configuration is proposed. The derivative control method is applied to provide virtual inertia. The virtual synchronous generator (VSG) topology is presented, and its elements are introduced. According to the frequency changes, the active power reference is generated. Moreover, the control structure is designed and presented to control the DTL VSI properly. By means of the derivative control method, the DTL VSI participates in the frequency regulation and the frequency oscillations during contingencies are confined. The results show that the controller follows its reference in all cases. The effectiveness of the proposed controller is verified through MATLAB simulations. Compared to the conventional DTL VSI, frequency nadir and rate of change of frequency (ROCOF) are reduced during disturbances.
