During the past few decades, power industries have proved that the adverse impacts on the PQ can be mitigated or avoided by conventional means, and that technique using fast controlled force commutated power electronics (PE) are even more effective. PQ compensators can be categorized into two main types. One is shunt connected compensation device that effectively eliminates harmonics. The other is the series connected device, which has an edge over the shunt type for correcting the distorted system side voltages and voltage sags caused by power transmission system faults. The STATCOM used in distribution systems is called DSTACOM (Distribution-STACOM) and its configuration is the same, but with small modifications. Recent advances in the power-handling capabilities of static switch devices such as 3.3kV, 4.5kV, and 6.5kV Insulated Gate Bipolar Transistors (IGBTs) with voltage rating commercially available, have made the use of the voltage source inverters (VSI) feasible for high-power applications. High power and high-voltage conversion systems have become very important issues for the power electronic industry handling the large ac drive and electrical power applications at both the transmission and distribution levels. For these reasons, new families of multilevel inverters have emerged as the solution for working with higher voltage levels. Multilevel inverters (MLI) include an array of power semiconductors and capacitor voltage sources, the output of which generate voltages with stepped waveforms. These converter topologies can generate high-quality voltage waveforms with power semiconductor switches operating at a frequency near the fundamental. It significantly reduces the harmonics problem with reduced voltage stress across the switch. This research work is mainly focusing on application of multilevel DSTATCOM for power quality improvement in distribution system with integration of RES. Matlab/Simulink based model is developed and simulation results are presented.
