Solutions for the grid integration of wind farms—a survey



This article presents a survey of different possible technical solutions for the grid integration of wind farms. These solutions concern the main problems encountered today and, whenever possible, examples of actual implementation in wind farm projects are given. More specifically the following types of solutions are discussed: choice of an appropriate wind turbine generator technology; solutions based on co-ordinated wind farms and power system operation; reactive compensation and voltage control systems; fault ride-through systems; energy storage systems; current limitation devices; directional protections; etc. Copyright © 2005 John Wiley & Sons, Ltd.
