Increasing levels of wind energy in modern electrical power system is initiating a need for accurate analysis and estimation of transient stability of wind turbine generation systems. This paper investigates the transient behaviors and possible direct methods for transient stability evaluation...

This paper investigates the possible site matching of the direct-drive wind turbine concepts based on the electromagnetic design optimization of permanent magnet (PM) generator systems. Firstly, the analytical models of a three-phase radial-flux PM generator with a back-to-back power converter...

This paper proposes a new method to find the capacity of a future wind farm regarding several limits of the grid system: voltage stability limits, thermal limits, voltage limits, load tap changing limitation and generator power output limitation. The method combines the optimization method and a...

A particle model for calculating turbine wake flow during the optimization of wind farm micro-siting is presented. This model treats the wake flow as virtual particles generated by the turbine rotor. Based on the pre-calculated flow field of empty wind farm, the motions of the particles are...

The bionic method to optimize the turbine layout of wind farm on complex terrain is developed. By employing the virtual particle model for wake flow simulation, the bionic method runs based on the flow field calculated by numerical simulations of air flow. It simulates the evolution of a turbine...
