The increasing penetration of wind power leads to the reduction of conventional power plants proportion and brings challenges to maintain the frequency stability of power system. The participation of wind generation in primary frequency control has become a serious concern under study. This paper presents two methods, pitch angle control and speed control to enable frequency control in dynamic process...
As penetration of wind energy goes high, many relevant issues have been dealt with. Among them, a novel active power control strategy, which we call load-following, has been investigated recently. While the conventional way is to extract energy from wind as much as possible, the load-following mode allows wind turbine generator to work away from the maximum power extraction. This is meaningful in...
Compared with constant speed constant frequency wind turbine, variable speed constant frequency wind turbine has many advantages: higher efficiency of wind energy converting to electric power, absorbing gust energy, smoothly cutting into the network system, flexible connecting between wind turbine and network system and low operating noise. Currently the variable speed constant frequency technology...
