Paul-Frederik Bach, The Variability of Wind Power

REF Publishes New Collection of Papers on Wind Power Variabiity in Germany, Denmark, and Ireland

At a launch event in central London on the 29th of July 2010 the Renewable Energy Foundation launched its Research Monographs on Energy with a new collection of papers by the leading Danish engineer, Paul-Frederik Bach.1

The Variability of Wind Power: Collected Papers 2009-2011 (x + 53pp) brings together five papers all concerned with the topic of wind power variability, and all grounded in rigorous examination of large bodies of empirical data.

The contents comprise:


  1. "Wind Power and Spot Prices in Denmark and Germany: Statistical Survey 2009"
  2. "Wind Power Variability: Observations and Analysis"
  3. "Wind Power Variations are Exported"
  4. "Geographical Distribution and Wind Power Smoothing"
  5. "The European Wind Integration Study Final Report"


In his preface to this work, Professor Michael Laughton,2 remarks that "There is much in this report of interest and value relevant to the future UK situation if the planned wind generation capacity both on and offshore materializes. It appears that the United Kingdom must consider significant regulatory and technical changes to grid operation if security of supply is to be guaranteed and costs to the consumer kept under reasonable control."

A low resolution copy of the book for download is available using the link below.

1. Paul-Frederik Bach worked with grid and generation planning at ELSAM the west Danish power station operator, until 1997, and then as Planning Director at Eltra, the Transmission System Operation, with special responsibility for integrating wind generation. He is one of Europe's leading grid engineers, and is still active in advising the Danish government on the direction of its policy.

2. Professor Michael Laughton is Emeritus Professor of Electrical Engineering at Queen Mary, University of London and a Fellow of the Royal Academy of Engineering. He is one of the UK's leading electrical engineers.
