What are static and dynamic load models?

Static and dynamic load models are used to represent the aggregate effect of power system loads on the performance of power systems. Several studies have been performed where static and dynamic analysis is performed; however, consideration of the wind power generating sources is not considered in most of these researches.

What are the dynamic characteristics of Integrated wind turbine drivetrain system?

The integrated wind turbine drivetrain system operates under variable-speed and variable-load conditions for a long time and is affected by multi-source excitation from the internal excitation of the gear system, the internal excitation of the generator, and the external wind load; hence, its dynamic characteristics are complex.

What are the components of a wind energy conversion system?

The major components of a typical wind energy conversion system, as depicted in Figure 1, include a wind turbine, an electric generator, interconnection interfaces and control systems. In certain application there is also a gearbox, in order to adapt the wind turbine rotation speed to generator characteristic for optimizing the harvested energy.

How to analyze wind energy conversion systems (wind turbines)?

In order to properly analyze wind energy conversion systems (wind turbines) there are usually used real time emulators, for cost reduction. Testing a wind turbine in a wind tunnel can be an expensive solution. Thus, an emulator can reproduce the behavior of a real wind turbine in different functioning regimes.

What factors affect the dynamic characteristics of wind turbine drivetrains?

In the traditional design and previous studies of wind turbine drivetrains, Qin et al. , , studied the internal excitation of the gear system (such as bearing support stiffness, time-varying mesh stiffness, and tooth side clearance) and its effect on the dynamic characteristics of wind turbine drivetrains.

Is wind energy stochastic?

Wind energy has a stochastic fluctuating behavior, being important to consider operation in transient non-stationary wind conditions . The major components of a typical wind energy conversion system, as depicted in Figure 1, include a wind turbine, an electric generator, interconnection interfaces and control systems.
