fáciles de calcular. La precisión de las previsiones durante este
periodo es fundamental a la hora de garantizar la confiabilidad
del funcionamiento y el despacho económico de todas las tecnologías.
Una mala previsión en el funcionamiento del sistema
también puede tener graves consecuencias económicas, financieras
y de confiabilidad. Esto puede depender del horizonte
de previsión y del mercado donde se produzca, así como de la
magnitud del error de previsión.
La confianza en la precisión de las previsiones y su
impacto seguirá aumentando en importancia (véase la figura
2) a medida que crezca la capacidad instalada de energía
renovable variable. Los procedimientos de compromiso de
la unidad pueden perder importancia debido a la disminución
de las fuentes que requieren mucho tiempo para comprometerse.

otros tipos de almacenamiento está muy condicionada por
