Control and Operational Approaches to Improve Frequency Stability of Electricity Grids with Increased Wind Power Penetration Levels

In many electricity grids around the world, wind power is becoming a preferred generation option over conventional generation. Long term environmental and economic benefits are the main reason for this trend. However, the intermittency of wind resources and limitations linked with the associated power electronic interfaces are seen to be barriers for adoption of this sustainable technology. The main concern is the adverse impact wind power could have on the stability of the power system. Despite the low marginal cost of operation, unpredictability of generation and the inability to assist the grid with ancillary services, at times, makes wind power a burden to the power system.
