Plenária
especial - 50 anos de Redes de Petri
|
|
As redes de Petri surgiram, para a comunidade científica, em 1962
quando Adam Petri apresentou sua tese de doutorado na Universidade de Bonn,
embora o conceito tenha sido criado em 1939 (vinte e três anos antes) quando
Petri tinha apenas 13 anos. Essa representação matemática para sistemas
distribuídos discretos encontrou vários domínios de aplicação, entre os quais
se destacam a automação da manufatura, protocolos de comunicação, bancos de
dados e sistemas distribuídos, de produção, de transporte, de informação e
logísticos.
Por essa razão o CBA 2012 está celebrando os 50 Anos de Redes de Petri.
Para tanto, está promovendo esta Sessão Plenária Especial.

Abstract

:

Power
systems engineers have always been on the forefront of exploring and
utilizing any new enabling technology, as it became available, to improve the
operation of power systems, i.e. making it smarter. Even though the term
‘Smart Grid’ has become ubiquitous very recently, its definition is
flexible.
Meaning
and understanding of Smart grid is usually multifaceted to variable
audiences. Although it is difficult to identify exactly what it is or
understand its potential advantages and concerns, one generic definition is
given as;
“A smart
grid is a digitally enabled electric grid that gathers, distributes and acts
on information about the behavior of all components in order to improve the
efficiency, reliability and sustainability of electricity services.”
Application
of adaptive and artificial intelligence control to one aspect of power
systems, that is improving the stability by improving the damping of local
and inter-area oscillations in an interconnected power system will be
described in this presentation. Basic theory and effectiveness of the
proposed approach will be illustrated by simulation studies and experimental
results of on-line real-time studies on physical power systems. It will be
shown how the use of modern control techniques can improve the power system
reliability by automatically tracking the system state thus making the system
smarter.

Abstract
|
:
|
Today’s Internet is a gigantic, complex
communications infrastructure, shared by end-to-end connections which compete
for the bandwidth resources. What is the resulting allocation? The answer is
highly dependent on multiple automatic control mechanisms embedded in the
network protocols, which dynamically adjust flow rates, routing, medium
access, etc., making the Internet probably the largest scale artificial
control system in operation. Is there any hope for a mathematical analysis or
synthesis at this huge scale? Research over more than a decade has shown that
substantial progress is possible by casting the problem in the language of
economic theory and convex optimization. These tools combine with methods of
dynamics and control to provide useful insights into current behavior, and
design proposals with provable performance at multiple protocol layers. In
this talk we will give a tutorial overview of this field of research.

Abstract
|
:
|
Optimization of electrical system performance is
important for the long-term economic viability of distributed and alternative
energy systems and it is very important to understand the integration of
these systems with the electric power grid. New markets and benefits for
distributed energy applications include the ability to provide ancillary
services, improve energy efficiency, enhance power system reliability, and
allow customer choice. Advanced power electronic interfaces will allow
increased functionality through improved power quality, increase electrical
system compatibility by reducing the fault contributions, and flexibility in
operations with various other distributed energy sources, while reducing
overall interconnection costs. The advances of power electronics are very
important for integrating alternative and renewable energy to the utility
grid, and in the last few years, the “Smart Energy” paradigm has been
embraced to ensure balanced economic growth and environmental sustainability,
and the new concept of “Smart Grid” became a critical enabler in the
contemporary world, with increased attention of policy makers and engineers.
