Flicker Propagation in Power Networks with Hybrid and Parallel Overhead Transmission Lines

Abstract

The growth of the energy generation from renewable sources necessitates the construction of new overhead transmission lines for the energy transport over long distances. The use of common right of ways (ROW) for several overhead lines becomes more and more popular. The construction of combined AC/DC hybrid power lines is one of possible solutions. The spatial proximity of several power lines in the common ROW intensifies electromagnetic interferences between the lines. These interferences can cause deteriorations of power quality parameters in power grids containing parts with common ROWs. The influence of electromagnetic interferences on the flicker propagation in power networks with hybrid and parallel overhead transmission lines is considered in the offered paper.
