Abstract: This paper presents the design and implementation of a new distribution static synchronous compensator (D-STATCOM) inverter with the modular multi-level converter (MMC) technology. The D-STATCOM inverter is used to correct the problems related to power quality and to enhance the reactive power compensation by using solar photovoltaic power. A D-STATCOM inverter with modular multi-level converter (MMC) technology is shunt compensation between a source and distribution grid. The phase angle and modulation index are used to regulate active and reactive power flow. Simulations of the D-STATCOM inverter, with 5 levels modular multi-level converter (MMC) technology, have done by using MATLAB/Simulink.
