Wind Power Generated by Quarter in UK

In follow-up to a couple of previous postings today and yesterday, someone expressed interest in the patter of Wind power generated in other units of time.  I chose to do the same analysis but breaking it into quarterly statistics from January 2009 to September 2010.  The following graph shows the trend in quarterly average power generated by wind.  Given the emphasis on growing wind power in the UK, I was surprised to see a lack of growth in recent quarters.

The histograms and fitted probability distribution curves follow pretty much the same pattern as the overall pattern, but are shown here for completeness:

    Another way of looking at it is by time of day

    and comparing it to electricity demand. Seems to illustrate the “diurnal effect” I think…. Wind speeds are broadly correlated to daylight or energy in the sun and it dies down at night.

    That’s my plan. I have both 30 minute and 5 minute interval data. I’m not doing it as a priority yet as by simple inspection of the data one can see the effect. But watch for it here over the next few days.

    I did the analysis by time of day for the means. See posting of 3 Nov. This doesn’t give the complete picture as more interesting is the amount of time there is little to know wind power. This is represented in the probability distribution which are next to be computed.
