Operational benefits from optimal volt/VAr scheduling in the South-East Australian transmission network

Abstract

The Victorian power system supplies the Australian Federal state of Victoria (population: 4.5 million; capital city: Melbourne) with electricity. Over the last three years, an extensive EMS computer system has been installed at the System Control Centre in Melbourne. It includes, amongst other functions, a complete set of optimal power flow (OPF) applications. This paper reports on the results gained during the first year of daily application of the optimal volt/VAr scheduling (VVS) function and ends with an outlook on planned future extensions.
