Abstract

Chapter one: Provides an overview of different wind turbine concepts and possible generator types. The basic configurations and characteristics of various wind generator systems based on contemporary wind turbine concepts are described with their advantages and disadvantages.
Chapter Two: Presents a detailed simulation and analysis of the transient response of WECT by doing these objectives (1) Assessment of stability of grid-connected Wind Energy Conversion Technologies (WECT) from the perspectives of Transient Stability (TS) and Transient Voltage Stability (TVS); (2) Stability analysis of grid-connected WECT as affected by their parameters; (3) Investigating the effect of Static VAR Compensators (SVC) in solving stability problems. The first objective is handled by two actions. The first action is studying the impact of Fault Clearing Time (CT) on the TS and TVS of the system; consequently, the Critical Clearing Time (CCT) is determined. The second action is studying the impact of the strength of the grid-coupling. The second objective is handled by performing a parametric study on both generating technologies. Various electrical and mechanical parameters are considered in this study.
Chapter Three: Provides an overview of the requirements imposed by international grid-codes for connecting large amounts of wind power to various electric power systems. The main concern here is the fault ride-through (FRT) capability requirements. The consistency of popular wind power technologies with the FRT requirements is evaluated considering the German E. ON Netz code. This is achieved through appropriate modelling and simulation of grid-connected fixed-speed and variable-speed wind power technologies. Two methods of evaluation are presented in the thesis.
Chapter Four: The impact of load models on power system performance is presented, and a comparative analysis of the impact of various load models on the performance of grid-connected wind power
