FACT Devices Examination for Voltage stability of WEC Integrated with Week Grid: Case study of a Selected Site

In today’s era the usage of wind power for generation of electricity is used invariably. In comparison with other sources like thermal power plant and Diesel Power plant it is clean and eco-friendly in nature In India use of renewable energy sources is growing day by day. Wind power is having excellent potential in India. Only problem associated with power is having variable attribute of wind which affects overall generation of power and there they need a reactive power management for generation. Now a Days several Wind power projects are operated in conjunction with the grid. The power generated from wind power plant is variable and it is requiring an efficient power control for these energy sources. Wind turbines must be able to recover short duration faults and voltage imbalances during speed variations without disconnecting from the grid. In this paper an attempt has been made to resolve the problem of voltage stability of concern old site which is in Madhya Pradesh India whose considered wind turbines is E- 31 Ratedi Enercon India. The voltage level of the considered gridconnected wind convertor is being analysed through its 1-year data under various operating conditions were output power varies with speed is simulated, also short duration faults are created on a prepared base model, the faults intensity is of E- 31 collected data via SCADA. All simulation work is been carried out in MATLAB 2021a Software. Finally the base model is simulated with FACT devices SSSC, STATCOM, SVC, UPFC and it is found that STATCOM device is best for Voltage Profile Imbalances for faults with shorter Durations.
