Application of Multi Level Inverter Using MMC and FACTS in Distributed Energy Systems

The paper proposes a new 1-ϕ Wind Energy Inverter which can be used for Wind Applications. The Proposed Inverter uses MMC topology so as to provide high efficiency, high power quality, and increased reliability. MMC topology has also other advantages such as low harmonic distortion, improved voltage balancing, and high voltage levels. The Wind Energy Inverter also has FACTS properties which regulates reactive and active power. The Inverter is installed in between wind turbines and the Power Grid. It converts incoming Direct Current from wind turbines to Alternating Current and maintains a target power factor, by regulating reactive power. Capacitor banks and external STATCOMS are no longer used, lowering the system’s total cost. The suggested inverter’s overall harmonic distortion is less than 5 percentage, which meets with IEEE specifications.
