This paper proposes a frequency regulation strategy applied to wind turbine generators (WTGs) in an isolated grid. In order to complement active power shortage caused by sudden load or wind speed change, an improved deloading method is proposed to solve inconsistent regulation capabilities in different speed regions and provide WTGs a certain capacity of power reserves. Considering the torque compensation...
A new control method based on PID for load frequency control in power systems is proposed in order to suppress frequency deviations due to load and generating power fluctuations occurring by increased penetration of renewable resources such as photovoltaics or wind farms. The variation of renewable resources can be considered to be a kind of load fluctuations. For the appropriate absorption of load...
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...
Due to the recent expansion of renewable energy applications, wind energy conversion is receiving much interest all over the world. However, output fluctuations of wind generators cause network frequency variations in power systems. This can decrease the power quality and then cause a restriction of wind farm installation, especially in an isolated power system, for example, power system in a small...
In 2005 the author published an article in North American Windpower magazine that discussed how in recent years power generation projects using wind turbines have been required to operate in a similar manner to conventional generating resources. The subject was later presented during Panel Session ldquoOptional Characteristics of Wind Farmsrdquo at the 2006 IEEE PES General Meeting held in Montreal,...
