Iberdrola’s New Curtailing Approach for Wind Farms Increases Power Delivered

Wind power has many environmental advantages and is becoming more economically competitive. As a sustainable energy source, wind power is likely to continue to grow at a fast pace for the next decades. With wind power shares increasing in Europe -- ranging from 35 to 8 percent in Denmark, Spain, Portugal, Ireland, and Germany -- a number of control challenges at both the turbine and transmission network (grid) levels surfaced during the past decade. Spain and other pioneering countries have gradually overcome these challenges. Today, a significant wind power share has become a stabilizing factor of the network.
When these challenges became apparent in Spain, the Spanish transmission network operator (TSO) was forced to issue setpoints to curtail wind power generation during certain periods of the day to balance supply and demand and guarantee safe operation. To meet the setpoint, while maximizing economic performance, Iberdrola Renovables implemented real-time information solutions based on advanced technology from OSIsoft in its Renewable Energy Control Center (CORE) in Toledo, Spain. Iberdrola Renovables is a worldwide leader in wind energy and a major player in Spain.
