Interconnection discussions relating to wind power projects

Can wind turbines and solar inverters contribute to frequency control?

Posted on February 6, 2012 by Administrator

Renewable energy resources such as solar and wind power are produced in a manner that is usually considered as not being able to contribute to frequency control of interconnected power systems.  For wind turbines, the reason for this is that … Continue reading →

Transmission bases for sizing wind and solar projects

Posted on October 18, 2011 by Administrator

Unlike base load power plants such as nuclear and some coal plants which operate near full capacity for days at a time, solar photovoltaic (PV) and wind farms are variable resources whose output is dependent on the minute-by-minute change in … Continue reading →

A Methodology for Estimating Potential Curtailment of Wind Farms

Posted on September 3, 2010 by Administrator

 by Pterra Consulting Figure 1 A wind farm integrated into a transmission grid is subject to curtailment due to temporary or long-term insufficient capacity on the transmission lines.  Maintenance outage of a nearby line, dispatch of competing wind farms and availability of other generators are examples … Continue reading →

High Voltage Concern at Wind Farms?

Posted on May 18, 2010 by admin

If we think about wind turbines as induction generators, one would assume that these would be VAR (reactive power) sinks, demanding vars from the grid to be able to deliver watts.  However, that may be true from the point of … Continue reading →
