Abstract
Aiming to better understand daily patterns of price in the Iberian Electricity
Market (MIBEL) we resort to a clustering analysis. The data regards the hourly
prices of electricity, in e/MWh, observed in the day-ahead MIBEL market
between 2016 and 2018. We propose clustering daily time series to obtain
groups of similar days according to the variation of the price throughout the day.
Alternative distance measures between time series are considered: Euclidean,
Pearson correlation and Periodogram based measures. K-Medoids algorithm is
used to form the clusters. The clustering solutions are selected by resorting to
several cohesion-separation measures. Finally, clusters are profiled.
