Wind power technologies from the perspective of system operator

Various wind turbines have been developed and operated in distribution systems and transmission systems. The usage of wind power is now rapidly growing worldwide and some leading countries in wind power technologies have been developing new strategies and enhanced requirements for power system security and electrical power quality. But most of power systems have not prepared for them yet. Given the fact that the renewable energy sources, such as wind power, photovoltaic, fuel cells will be getting more importance for the future energy systems with the benefit of emission trading, most of developing countries and power systems that are not preparing for such movement should make their future plan not only for the power system security, but also for their economic development. In this paper, wind power technologies, which is one of the most promising alternative energy sources, is summarized from the viewpoint of power system operation and control.
