One month load curve

The charts below show the average power use in 5 minutes intervals, along one whole month of electricity use.
The first one shows the curves separated for weekdays and weekends, the second one is just an average for the whole month.





The most surprising effect of this "averaging" process for me is the fact that the highest power peak present on the average chart is below 1100W, while the highest power sample on the source data was 6794W, during a short period on a Weekend day, at 20:48h, in the evening. The reason why this happens is because I averaged the values of power for each 5 minutes of each day of the month and while on some days this value was high, on others it was very low. I guess I'll need a lot more days of analysis to be able to draw more accurate conclusions.

It is however interesting to see the difference between week days and weekends, although in our particular case that difference is surely smaller than with normal families, because we homeschool the kids, so there is always people in the house, even at week days.

The other interesting conclusion is about where are the energy "mountains". There are two smaller ones, one in the morning and one other at lunch time, and then there are two bigger ones which correspond to dinner time and to "cloth washing time". We have double tariff, so we tend to turn the washing and drying machines late in the evening, that is the second high energy peak of the day.

Let's see in the future, with more data gathered, if these curves will change significantly.
