Análise da contratação de energia de fontes termoelétricas na composição do sistema interligado nacional
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2014-08-26)
Along the years 2011 to 2013, the National Interconnected System underwent some changes, one related to increased hiring by thermoelectric energy sources. Thus, this study aims to examine the motivations and implications ...
Metodologia de análise do colapso de tensão em tempo real considerando limites de potência ativa e reativa de geradores
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Sistemas de EnergiaUTFPR, 2017-09-29)
Due to the high energy demand and the high complexity of today's interconnected Electrical Power Systems (SEPs), it is becoming increasingly important for the system operator to know the current state of the SEP. In addition, ...
Flexible investment decisions in the European interconnected transmission system
(Elsevier Science, 2011-04)
Investment decisions in the power transmission system are vulnerable to substantial long-term uncertainties. Especially, in large interconnected power systems like in Europe, the impact of different influencing factors on ...
Decentralized AC power flow for real-time multi-TSO power system operation
(2010-12-06)
This paper adjusts decentralized OPF optimization to the AC power flow problem in power systems with interconnected areas operated by diferent transmission system operators (TSO). The proposed methodology allows finding ...

Identificação de ilhamento elétrico em redes de transmissão de energia
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Eletrotécnica, 2015-02-13)
The real-time operation of a power electric system (SEP) is an extremely complex task, and therefore requires several functions analysis and control of the network. Thus, interruption of the energy supply and the formation ...
Manipulability of Cost and Benefit Allocation in Cross-border Electrical Interconnection Projects
(IEEE, 2019)
Cross-border electrical interconnection projects are getting more attention all over the world. In this context, cost-benefit allocation is especially important due to the need for fair sharing of power trading benefits ...
Análise de transitórios eletromecânicos através do programa ANATEM
(Universidade Tecnológica Federal do ParanáCuritibaBrasilCurso de Engenharia ElétricaUTFPR, 2018-12-04)
The transient stability analysis in electric power systems is very important for the correct functioning of the system. When there is an occurrence of a given disorder in the system, through this analysis is possible to ...
