de control basada en DDPG no
ubica al punto de ajuste en el valor
más bajo posible incluso durante
las horas de precio máximo para
evitar las infracciones al confort
durante los momentos en los que
la temperatura exterior es extremadamente
baja. Estas comparaciones
demuestran que, una
vez que está bien entrenado, el
control del DDPG ha aprendido
el impacto de la señal de precio
y la temperatura exterior sobre
la recompensa, y desarrolla una
estrategia inteligente de control
del punto de ajuste a fin de contemplar
el precio máximo y la
temperatura exterior baja.
La figura 6(c) ilustra el caso
de punto de ajuste fijo,
llamado
así porque esta estrategia de control
siempre fija la temperatura al
mayor valor. Por ende, la temperatura
interior también permanece
en el nivel más alto entre las tres
estrategias de control. Entonces,
el control del punto de ajuste fijo
ocasiona el costo más alto de la
energía.
Nótese que, al calcular las
infracciones a la temperatura o al
confort, solo cuenta el momento
en el que la temperatura interior
es menor al límite inferior. Esto
se debe a que este es un escenario
de calefacción, y una temperatura
interior baja se considera una
infracción insoportable, mientras
que una temperatura interior alta
es aceptable para los usuarios de
HVAC residencial.
En el segundo escenario, la
estrategia de control del DDPG
entrenada previamente se valida
con 10 modelos de edificios
nunca antes vistos con distintos
parámetros de masa térmica para
demostrar su capacidad de generalización.
La tabla 3 ilustra una
comparación entre los costos de
la energía y las infracciones a la
temperatura para el control del
DDPG y dos controles de referencia
ya mencionados. Como
muestra la tabla, al igual que en
