Kurzbeschreibung (Abstract)
This paper investigates the influence of various DC network configurations on the optimal operation of a hybrid ACDC transmission grid with DC overlay network. An optimal power flow algorithm focusing on minimizing the losses in the system is developed considering various configurations of the DC overlay grid, connected with the high voltage direct current (HVDC) converters. It is observed that different DC network configurations lead to major changes in the power flow of the existing grid and a more meshed configuration could be potentially utilized for reducing the transmission losses for the AC network. Using a MATLAB based interior point solver, the optimal power flow method is validated for a 66 bus hybrid AC-DC transmission test system for three different stages of the DC network development. Minimum amount of transmission losses has been observed for a fully meshed HVDC network configuration in the hybrid AC-DC network.
