una serie de mediciones virtuales,
derivadas y seudomediciones.
Cada medición se expresa en
función de los estados de la subestación.
De este modo, todos los
componentes del sistema eléctrico
se modelan como un modelo
dinámico trifásico con base física
que incluye neutro y tierra. Los
componentes incluyen líneas de
transmisión, transformadores,
generadores y otros. Toda medición
en cualquier componente
del sistema eléctrico utiliza este
modelo para derivar el modelo
matemático de la medición en
función de las variables de estado.
Este enfoque da como resultado
una representación de alta fidelidad
de cualquier medida en el
sistema y la capacidad de estimar
el comportamiento dinámico y
transitorio del sistema eléctrico.
La formulación DSE incluye los
siguientes pasos:
✔ Todas las mediciones se expresan
como un objeto (expresión
matemática de una
medición en función del
estado de la subestación).
Este objeto es una función
no lineal con términos algebraicos
y diferenciales.

✔ El objeto se convierte en una
función no lineal con no linealidades
no superiores a
cuadráticas (por ejemplo, cuadrados
de variables) mediante
la introducción de variables
de estado adicionales si es
necesario. Posteriormente, se
aplica un método de integración
numérica para convertir
cada modelo de medición en
una forma algebraica complementaria.
Se utiliza el método
de integración cuadrática y,
en particular, el método de
los tres puntos de colocación
de Lobatto. El resultado final
es que el objeto de cada medición
está en una forma algebraica
complementaria con
no linealidades no superiores
a las cuadráticas.
