La evolución de los impactos de las FED
Volúmenes significativos de FED presentan desafíos y oportunidades en toda la red, lo que requiere cambios a la previsión, planificación y operación. La figura 4 ilustra el mayor
alcance y profundidad de la planificación para los DNSP.
Además de considerar la demanda máxima, los planificadores
y operadores de la red ahora necesitan estimar las demandas
mínimas y subyacentes (sin generación de energía FVD). No
obstante, sigue existiendo una visibilidad muy limitada de las
FED y, de hecho, de la red de baja tensión. Los ensayos proporcionan información muy necesaria sobre las condiciones
operativas reales e ilustran los desafíos clave. Por ejemplo, el
ensayo de SAPN de la VPP de Salisbury conectó 100 BESS
con sistemas FVD en instalaciones residenciales de los suburbios de Adelaida. Los datos operativos del ensayo demuestran
la evolución de los desafíos de integración de las FED en la
red de distribución. Las implicaciones de las VPP para la operación del sistema se plantean en otra sección más adelante.

Históricamente, la principal preocupación para los planificadores y operadores ha sido asegurar que los límites térmicos de la red no se sobrepasen durante los días de carga
de demanda máxima ( a en la figura 5). Los altos niveles
de generación de energía FVD hacen que la gestión de la
tensión sea un desafío clave, como lo indica b en la figura 5.
En esta instancia, es probable que la exportación de VPP sea
lo suficientemente grande para elevar la tensión por encima
del rango permitido. El ensayo de Salisbury destacó que la
coordinación de las FED también supone nuevos desafíos.
El ensayo demostró que la operación de las VPP puede provocar picos extremos en la demanda que superen significativamente la carga máxima normal de verano, por ejemplo,
cuando se dieron instrucciones de cargar todas las baterías
ante la previsión de un frente de tormenta ( c en la figura 5).
Por el contrario, si se dan instrucciones de descargar las VPP
en medio de un día de sol durante un evento de precios altos o
de proporcionar control de frecuencia y servicios auxiliares
