obituario

en memoria de
William F. (Bill) Tinney (1921-2019)

W

WILLIAM F. (BILL) TINNEY FALLECIÓ
en Portland, Oregon, el 14 de abril de
2019, tres semanas antes de cumplir
98 años. Fue considerado ampliamente como el padre de las soluciones informáticas modernas para las redes de
energía eléctrica, y sus pioneras contribuciones tuvieron una profunda influencia en el crecimiento de las redes
eléctricas actuales.
En 1943, después de dos años de
estudiar ingeniería eléctrica en Oregon
State University, Corvallis, Tinney se
alistó en el Ejército de los EE. UU. Y
se convirtió en oficial de radar, con entrenamiento en Massachusetts Institute
of Technology y Harvard University,
ambos en Cambridge, Massachusetts.
Después del ejército, obtuvo su licenciatura y maestría en Stanford University,
California. Trabajó en la Bonneville
Power Administration (BPA), Portland,
Oregon, desde 1950 hasta 1979 y realizó su innovador trabajo en la sección
de análisis de sistemas. Después de retirarse de la BPA, se convirtió en consultor independiente de proveedores de
software de sistemas de energía.
El importante artículo de 1967 de
Tinney, "Direct Solutions of Sparse Network Equations by Optimally Ordered
Triangular Factorization" (Soluciones
directas de ecuaciones de redes dispersas por factorización triangular con orden óptimo), del cual fue coautor con JW
Walker y se publicó en Actas del IEEE,

William F. Tinney

revolucionó la solución de sistemas de
energía eléctrica a través de la nueva explotación de la dispersión de la matriz de la
red (que inspiró mucho
trabajo de la comunidad
matemática en soluciones de matriz dispersa
más generales). En el
campo de la energía
eléctrica, hizo posible
resolver grandes modelos de redes de transmisión de forma rápida
y exacta. Esto lanzó una
ola de innovación para
adaptar la tecnología
a las herramientas de
software convencionales, como el flujo de energía, el flujo
de carga óptimo, la estimación de esta-

do, el análisis de estabilidad, el análisis
de fallas, el suministro de seguridad, la
reducción de red y los precios por congestión del mercado. Tinney colaboró en
muchas de estas pioneras adaptaciones,
como se informó en los documentos de
transacciones de la Power and Energy
Society (PES) del IEEE.
Las innovaciones de Tinney son
igual de relevantes hoy que siempre.
Prácticamente todos los programas informáticos de sistemas de energía eléctrica desarrollados durante los últimos
50 años se basan en su solución de red
dispersa. A medida que las computadoras avanzan, sus técnicas hacen posible
llevar a cabo simulaciones y optimizaciones de redes eléctricas cada vez más
complejas en modelos más grandes y
más detallados que involucran muchos
miles, o incluso millones, de soluciones
de sistemas e incluyen
aplicaciones críticas
en tiempo real para la
economía y seguridad.
Tinney tuvo un efecto
inconmensurable en la
planificación, el diseño
y el funcionamiento
confiable de las redes
eléctricas del mundo,
que van desde el nivel
de los servicios públicos hasta el modelado a
lo largo del continente.
Si bien la tecnología de dispersión es fundamental
para todas estas aplicaciones de red,

Fue considerado
ampliamente
como el
padre de las
soluciones
informáticas
modernas para
redes de energía
eléctrica.
