In this paper, a new single-phase wind energy inverter (WEI) with flexible Ac transmission system (FACTS) capability is presented. The proposed inverter is placed between the wind turbine and the grid, same as a regular WEI, and is able to regulate active and reactive power transferred to the grid. This inverter is equipped with distribution static synchronous compensators option in order to control the power factor (PF) of the local feeder lines. Using the proposed inverter for small-to medium- size wind applications will eliminate the use of capacitor banks as well as FACTS devices to control the PF of the distribution lines. The goal of this paper is to introduce new ways to increase the penetration of renewable energy systems into the distribution systems. I Considered a single phase voltage sources in the series RLC Branch at the grid side, similarly a single-phase asynchronous Machine are placed at Load side, the d-stastcom and Pv cell are placed in between AC Voltage source and wind turbine. In this paper modular multilevel converter is utilized to meet all the requirements of IEEE standards the total harmonics distortion (THD), Active and Reactive of the system are calculated. The proposed 15-level inverter is a single-phase wind energy inverter is placed between the wind turbine and the grid, The function of inverter can manage active and reactive power transfer to the grid and wind turbine, as well as keeping Pf constant at wind turbine. Active and Reactive power from the grid, Turbine and inverter side was calculated, and also calculated line voltage of wind turbine and Inverter. The simulation Results of a 15-level inverter have been done in MATLAB/Simulink.
