Dynamic disturbance of wind farm connected to 14 bus network

Induction generators are the most popular in wind energy conversion system due to its simplicity and absence of synchronization problem. However the major drawback of this machine is its additional reactive burden on the electric network. This paper studies the voltage stability of wind farms (WFs) Connected to IEEE 14 bus network during system disturbances such as a load change, three phase fault or island condition. Those disturbances have a great impact on the system voltages and frequency. A static synchronous compensator (STATCOM) is proposed to maintain voltage and frequency within grid codes requirements. The proposed system shows an excellent performance it maintains the voltage and frequency constants by injection controllable reactive power during system disturbances. MATLAB/SIMULINK and the Power System Analysis Toolbox (PSAT) package are used for the simulation.
