Wind energy has been receiving more acceptance as a reproducible, resourceful and clean energy source since last decade. Wind power is not constant and can fluctuate below the rated wind power when the wind speeds are lower than the rated wind speed. This fact affects the grid the wind generators are connected to, which is becoming more significant with the increasing penetration of wind energy systems...
This paper investigates the influence of inverter nonlinearity on the parameter estimation in permanent magnet synchronous machines (PMSM). An estimator based on model reference adaptive system (MRAS) is firstly described for simultaneously estimating the stator winding resistance and rotor flux linkage, together with injection of a pulse of id <; 0 which is required for activating the estimation...
With the increasing wind power penetration, the wind farms are directly influencing the power systems. Therefore, analysis of wind power dynamics has become a very important issue, which justifies the need of a detailed dynamic model of wind power generation system. This paper approaches towards the study on the effect of wind speed variations and machine inertia constants on transient during initialization,...
