Abstract
The main goal of this paper is to design, control, and perform power quality analysis in the LVDC domain by using a three-level neutral point clamped converter. A ± 500 Vdc two-terminal VSC-LVDC distribution system uses, and time-domain simulation model is implemented in the Simulink environment. The stability of network controllers VSC (voltage & power) has analyzed during voltage and power perturbations. Furthermore, the power quality and faults in the DC network are studied. The inclusive simulations show the transients in DC bus voltage, while the proposed filter design can limit adequate harmonics content in the customer-end network. Finally, the LVDC faults analysis propose an advanced control strategy that can offer robust performance during steady-state and transient conditions, while improved DC voltage handling capabilities.
