Stability Enhancement in Grid Integrated Real Time Wind Energy Conversion System with Compensating Devices

摘要

This research works aims to do an analysis for the implementation of reactive power compensation scheme for grid integrated Wind Energy Conversion Systems (WECS) using Flexible AC Transmission System (FACTS) devices. The instability problem occurs mostly in the power system, where the wind farm is connected electrically far away from the grid. The stability of wind energy generators are based on wind turbines are analyzed in this paper. Due to the characteristics of a synchronous generator, instability differs. It is suggested that the usage of FACTS devices such as Static VAR Compensation (SVC) and Static Compensators (STATCOM) are to improve the stability in the grid connected wind farms. For the simulation analysis, wind farm models based on induction generator, equipped with SVC and STATCOM, connected to power systems have been developed in MATLAB/SIMULINK software.
