✔ Un enfoque basado en perfiles
horarios medios para cada
consumidor: para cada hogar,
se computan las medias (características)
de 24 horas y se
aplica un algoritmo de media k
a cada macrogrupo usando estas
24 características. En este
caso, el número de subgrupos
es tres.
✔ Un enfoque basado en los perfiles
horarios del percentil 95
para cada consumidor: este
método es como el enfoque anterior,
pero utiliza percentiles
del 95 en lugar de medias. Este
enfoque puede ser útil cuando
la atención se centra en la demanda
máxima.
✔ Un enfoque basado en el autoconsumo:
para cada hogar,
la función de autocorrelación
de la serie temporal correspondiente
se calcula para capturar
el comportamiento dinámico
individual. En este caso, hemos
considerado las primeras
168 autocorrelaciones, pero
para reducir la dimensionalidad,
hemos seleccionado las 19
más relevantes: 1, 2, 3, 4, 5, 6,
8, 9, 10, 11, 12, 13, 24, 25, 48,
49, 72, 73 y 168. Cabe destacar
que capturan la dinámica en el
muy corto plazo, pero también
en el primer, segundo, tercero
y séptimo días previos.
La figura 4 muestra los centros
de agrupación para tres divisiones
más finas de cada macrogrupo
calculadas en la subsección anterior.
La división más fina se basa
en el primer enfoque (perfiles
horarios medios). Los
