Abstract :

Wind power has been used for centuries with different purposes such as pumping water, propelling boats or grinding corn. Voltage variation problems in steady state leading to flickering which is caused by towers had own effects and voltage drop at PCC due to sudden loading effects constitutes one of the implications of the wind power integration that requires special attention. In facilities with moderated power generation, the WF are connected through medium voltage (MV) distribution headlines. A situation commonly found in such scheme is that the power generated is comparable to the transport capacity of the grid. This case is known as Wind Farm to Weak Grid Connection, and its main problem is the poor voltage regulation at the point of common coupling (PCC).So custom power device called UPQC is employed to mitigate these problems & to get the stable output from wind farms. This approach increases the compensation capability of the UPQC with respect to other custom strategies that use reactive power only. Simulations results show the effectiveness of the proposed compensation strategy for the enhancement of Power Quality and Wind Farm stability
