estados de los EE. UU. Si los estándares de cartera para energías renovables fueron un gran paso en la dirección correcta,
han demostrado la capacidad de hacer cambios drásticos para
sus respectivos estados, y el resto de los Estados Unidos está
observando. Hasta principios de 2019, hasta 125 ciudades, 11
condados y siete estados se han comprometido a alcanzar objetivos de energía 100% limpia dentro de (aproximadamente)
los próximos 20 años. Estos cambios no son específicos de los
Estados Unidos únicamente, sino que se trata de un fenómeno
mundial. Algunas ciudades de todo el mundo afirman que ya
han alcanzado sus objetivos. Todo esto significa que la cantidad de energía procedente de fuentes renovables que llega a la
red es significativa y seguirá incrementando.
El sistema de potencia eléctrica está cambiando de las
siguientes maneras (Gráfico 1):
✔✔ Cada vez más energía proviene de fuentes distribuidas
intermitentes y menos predecibles, dando como resulenero/febrero 2020
tado una mayor variabilidad del suministro. También
está aportando nuevos niveles de complejidad, cambiando la potencia que se mueve en una dirección a
través de la cadena de valor (generación-transmisión-distribución-cliente) a la potencia que ahora
puede moverse en todas las direcciones, desdibujando
las categorías de transmisión y distribución (T&D).
En ambos niveles de T&D, la cantidad de energía suministrada por fuentes renovables ha ido aumentando constantemente, acompañada de una disminución
igualmente constante de la energía suministrada por
la generación centralizada y despachable procedente de generadores impulsados por combustibles fósiles, como el carbón. Los cambios en la intensidad
del viento y del sol y el uso reducido de la generación
de combustibles fósiles requiere que el sistema proporcione maneras de agregar o quitar potencia muy
