de transmisión y distribución no están separadas. Existe
la posibilidad de pasar por alto niveles para la función de
restricción FV, pero esto podría mitigarse con facilidad
mediante la coordinación dentro de la TGRD.
Esta estructura futura agrega una capa a través de la
introducción de un coordinador del agregador destinado a
disminuir la carga operativa de la TGRD. Esto significa que
varias entidades pueden controlar o suministrar recursos del
lado de la oferta y de la demanda, lo que crea posibilidades
de acoplamiento oculto porque los conjuntos desarticulados de las FED en el mismo sistema pueden ser instruidos
por agregadores separados (terceros o minoristas). El rol de
coordinador del agregador en esta estructura puede ser capaz
de mitigar este problema si sus responsabilidades incluyen la

coordinación del suministro respectivo de FED para BPS y
distribución. La pregunta que se plantea aquí es si los agregadores separados podrían perseguir metas diferentes para
la agregación de FED o actúan simplemente como interfaces
estratificadas.
Además, las múltiples capas propuestas de la organización entre las FED y la TGRD, en especial si existe un
coordinador del agregador, significan que hay un problema
de latencia en cascada que limitaría la acción rápida que
involucra a las FED. Sería necesario un control localizado
para responder a las variaciones a corto plazo en la salida
solar. Es posible que el operador del mercado de energía y
la TGRD necesiten interactuar, pero esto podría resolverse
a través de las conexiones al minorista de energía. Además,
es probable que esta estructura asigne responsabilidad en
los agregadores y en el coordinador del agregador para proporcionar ciberseguridad para los flujos de datos hacia las
FED y desde ellas, lo que puede ser un problema en términos de roles y responsabilidades si estas entidades no están
reguladas. El uso de agregadores y de un coordinador del
agregador proporciona cierta cantidad de escalabilidad de la
comunicación, pero centralizar la coordinación de las FED
causará problemas de escalabilidad computacional en el
nivel de transmisión si la penetración de las FED se vuelve
alta. Una estructura estratificada más regularizada podría
ayudar a abordar varias de estas características indeseables.
