“…Transmission switching has been explored in the literature as a control method for problems such as over-or under-voltage situations, line overloads [6], loss and/or cost reduction [7], improving system security [8], or a combination of these [9] [10] [11]. Our investigation of optimal transmission switching extends this literature by probing the degree to which transmission switching could increase economic efficiency of power system dispatch.…”

“…In our analysis we defined all transmission lines as contingencies, and a violation was considered any line flow above 110 percent of normal, a value that is conservative compared to acceptable post-contingency line flow limits. 8 First, an n-1 contingency analysis was performed for the base case transmission topology. Twenty nine line violations were found in the base case, with line overloads ranging from 110 to 237 percent.…”

“…Transmission switching has been proposed as a corrective mechanism for problems such as over or under voltage violations, line overloading, and system security, see [2], [4], [11], [12], [21], [31]- [34]. Transmission switching can also be used to help reduce system losses, see [3] and [10], and it can be used as a congestion management tool as well, [13].…”

“…Ao longo dos últimos 30 anos, propuseram-se alguns algoritmos para implementação de Chaveamentos Corretivos, objetivando diferentes aplicações: Koglin and Müller (1980), Koglin and Medeiros Júnior (1983), Rossier and Germond (1983), Koglin and Medeiros Júnior (1985), Mazi et al (1986), Medeiros Júnior (1987), Medeiros Júnior (1987), Schnyder and Glavitsch (1988), Wrubel et al (1996) e Shao and Vittal (2005) objetivavam eliminar sobrecargas em linhas de transmissão; problemas relativos à tensão nos barramentos de subestações foram considerados nas proposições de Koglin and Medeiros Júnior (1987), Medeiros Jú-nior (1987) e Shao and Vittal (2005). Já o objetivo de Bacher and Glavitsch (1986) e Schnyder and Glavitsch (1988) era aumentar a segurança de sistemas elétricos.…”

“…Já o objetivo de Bacher and Glavitsch (1986) e Schnyder and Glavitsch (1988) era aumentar a segurança de sistemas elétricos. Em 1998, Rolim and Machado (1999) apresentou uma revisão acerca das publicações que empregavam a técnica de Chaveamentos Corretivos para aliviar sobrecargas em ramos e para solucionar problemas relativos à tensão.…”
