Abstract

The interlinking converters is one of the important components in the hybrid mirogrid system, the study of structure and control method of the interlinking converters in hybrid mirogrid has been implemented and achieved positive results. This paper proposes an improved decentralized control of level-shifted carrier-based PWM for a modular multilevel interlinking converter (IC-MMC) in standalone hybrid microgrid (HMG-Hybrid Microgrid). Main research objectives is to study the capability of the decentralized control method proposed for the IC-MMC unit when performing the power exchange control task between the DC and AC bus in the HMG system, increased flexibility in controls. Furthermore, the proposed control method for IC-MMC for HMG is also verified in term of dynamically reconfiguration when changing the number of modules in the MMC when the improve of system reliability is needed. The feasibility of the carrier level shift control method for IC-MMC in HMG has been verified by simulation model on MATLAB/Simulink software to evaluate the ability to exchange power between the DC bus and the AC bus.
