With the development of wind power, the inherent characteristics of randomness and uncertainty of wind energy would have an impressive effect on power system frequency, it is necessary for wind farm to participate in frequency regulating in order to share the burden with the frequency-regulating power plants, and to improve power system stability. Two operation modes of the wind farm are proposed...
Currently, there are several published reports on wind power detailing various researches based on such subjects as pitch angle control, variable speed wind turbines, energy storage systems, and so on. These reports propose output power leveling to reduce the adverse effects of power system frequency deviation. In this context, it is desirable to decrease frequency deviations of power systems by output...
Many isolated small power systems are powered by diesel generators, which results in greater operating costs than interconnected large grids. It is therefore desirable to integrate renewable energy sources such as wind power into these small grids. However, due to the fluctuating power generation from renewable energy sources, frequency deviations of power systems become problematic. Distributed intelligent...
As wind turbine output is proportional to the cubic of wind speed, the wind turbine generator output fluctuates due to wind speed variations. Hence, if the power capacity of wind power generators becomes large, wind power generator output can have an influence on the power system frequency. Some methods for smoothing the wind generator output fluctuations using several types of energy storage systems...
