(FCAS, por sus siglas en inglés),
entonces los límites térmicos y
de tensión pueden sobrepasarse
debido a los flujos de potencia
inversos ( d en la figura 5).
Este artículo se centra en el
aumento de los rangos de tensión,
los flujos inversos y las implicaciones de la energía FVD para
la seguridad del sistema, y cada
sección describe sus desafíos y
soluciones. Sin embargo, constantemente surgen más dificultades y oportunidades, como las
implicaciones en el diseño de la
protección para el sistema de distribución y transmisión, la gestión
de la potencia reactiva, el desprendimiento de carga por subfrecuencia y las capacidades de arranque
autógeno del sistema.
