Power Quality enhancement in Microgrid (Islanding Mode) by Using ND - MLI DSTATCOM

Microgrids are systems with clusters of micro generators, which are installed for distributed power generation. When interfaced to the utility grid, microgrids are exposed to common utility power-quality disturbances. The paper focuses on the combination of wind, FC and MT for sustained power generation. We propose herein a dynamic model, design and simulation of a wind/FC/MT hybrid power generation system with power flow controllers. The general function of the multilevel inverter is to synthesize a desired AC voltage from several levels of DC voltages. As the number of voltage levels increases the harmonic content decreases significantly. The modulating technique is modified reference modulating techniques. i.e., third harmonic injected reference and offset line voltage injected reference with triangular carrier waves. The main objective of this study is to reduce total harmonic distortion. A novel technique for the selection of switching states to synthesize the desire vector is proposed. This paper realizes the implementation of five-level diode clamped MLI
