“…Similar classification of the IEEE 30-bus network containing six generator bus and thirty-five load bus shows that GG is 4.88 per cent, GL is 19.51 per cent and LL remains the most occurring with 75.61 per cent of the total line occurrence. In general, from a primary electrical circuit, the power system is primarily designed to transport power from the generator to load (source to sink); therefore, in any switching operation, much limitations are expected on the GL lines as compared to GG and LL lines (Hedman et al , 2008; Golabi et al , 2013; Wahlström et al , 2005).…”

“…The process selects switchable line candidates and through a modified constraint programming language extension (CPLEX) solver reduces the number of integer variables present in the MIP problem. As a follow-up, analysis of various techniques and static switching security in multi-period considerations that may limit overvoltage during immediate dispatch of power flow after switching operations, is discussed (Golabi et al , 2013; Liu et al , 2012b). These dispatches focus greatly influenced investigations on the impact of various DC and AC switching solutions on the transmission lines of optimal capacity during power flow operation.…”

Purpose This paper aims to survey the need for full capacity utilisation of transmission lines in power systems network operations. It proposes a review of the N-1 security criterion that does not ensure reliable dispatch of optimum power flow during outage contingency. The survey aims to enlarge the network capacity utilisation to rely on the entire transmission lines network operation. Design/methodology/approach The paper suggests transmission line switching (TLS) approach as a viable corrective mechanism for power dispatch. The TLS process is incorporated into a constraint programming language extension optimisation solver that selects the switchable line candidates as integer variables in the mixed integer programming problem. Findings The paper provides a practical awareness of reserve capacity in the lines that provide network security in outage contingency. At optimum power flow dispatch, the TLS is extended to optimal transmission line switching (OTLS) that indicates optimal capacity utilisation (OCU) of the available reserve capacity (ARC) in the network lines. Practical implications Computational efficiency influenced the extension of the OTLS to optimal transmission switching of power flow (OTSPF). The application of OTSPF helps reduce the use of flexible AC transmission systems (FACTS) and construction of new transmission lines.. Originality/value The paper surveys TLS efforts in network capacity utilisation. The suggested ARC fulfils the need for an index with which the dispatchable lines may be identified for the optimal capacity utilisation of transmission lines network.
