Estimation of Total Transfer Capability in Intersystem Tie Lines of Electric Power Systems

Glazunova A.M., Aksaeva E.S. Estimation of Total Transfer Capability in Intersystem Tie Lines of Electric Power Systems // IFAC-PapersOnLine. Vol.51. No.32. 2018. P.331-336. DOI: 10.1016/j.ifacol.2018.11.405 The paper presents a method for real-time calculation of total transfer capability on the basis of a trade-off approach, witch gives optimal values of total transfer capability in all considered lines. To implement the trade-off approach we introduce a two-level structure to control the interconnected...

Active powers at the connection nodes of the non-linear loads to the high voltage network

... analysis of harmonic active powers at the nodes connecting the 220 kV supply network to three large-capacity nonlinear loads: an aluminum smelter shop, a paper mill and a traction substation. The equipment of the facilities is the source of harmonics. The measurements were used to calculate active power for harmonics. The calculations show that although the facilities are the sources of harmonics and generate harmonic active powers to the supply network they also receive harmonic active powers from the ...

Research into harmonic power in the high-voltage networks

... high-voltage networks // Renewable Energy & Power Quality Journal. Vol.1. No.14. 2016. P.696-701. The paper presents the results of studies on the harmonic active and reactive power at nodes of 110 kV and 220 kV networks. The studies were based on the measurements made at the node of 110 kV network supplying power to an aluminum plant and at the node of 220 kV network supplying power to railway traction substation. The supply networks belong to the Unified Energy Systems of Russia. Many other facilities ...
