Design of Microgrid with Distribution Static Synchronous Compensator (D-STATCOM) for Regulating the Voltage Fluctuation

Future of small and isolated power system depend on microgrids based on solar and wind power plan, which the technology is immature. Poor power factor and voltage fluctuation could affect the system's power quality, which can decrease the reliability. This paper discusses about the power factor correction and voltage fluctuation improvement using distribution static synchronous compensator or D-STATCOM. For demonstrating the proposed idea, D-STATCOM is installed on a radial distribution system and simulated under different operating condition. Variable and flexible reactive power support from this device corrects the power factor and regulates the voltage. The performance of D-STATCOM installation is proven by simulation in increasing the system power factor and voltage regulation.
