Impact of Wind Generation on a Transmission System

Wind power is one of the most mature and cost effective resources among different renewable energy technologies. Wind energy has gained an extensive interest and become one of the most promising renewable energy alternatives to the conventional fuel based power resources. Despite various benefits of the wind energy, the integration of wind power into the grid system is difficult to manage. The distinct feature of the wind energy from other energy resources is that its produced energy is "intermittent". Because the Wind Power is an unstable source, its characters feeding into the electric grid are different from the traditional energy sources. Though several reports have been published to investigate the impact of the wind power on the power system, this is a system dependent issue that requires to perform system specific impact study. This paper discusses the impact of power flow, short circuit current, and power quality when connects a proposed 68 MW wind farm into a 69 kV transmission system.
