Impact of converter losses on the optimal power flow solution of hybrid networks based on VSC-MTDC
Zhao, Q.; García González, J.; Gomis Bellmunt, Oriol; Prieto Araujo, Eduardo; Echavarren, F. M. (2017-10)
Article
Open AccessThis paper studies the impact of voltage source converter (VSC) losses on the solution of the optimal power flow (OPF) of hybrid AC/DC systems with a multi-terminal configuration. The motivation of this analysis is that ... -
Optimal power flow operation of an interline current flow controller in an hybrid AC/DC meshed grid
Sau Bassols, Joan; Zhao, Q.; García González, Javier; Prieto Araujo, Eduardo; Gomis Bellmunt, Oriol (2019-12-01)
Article
Open AccessThis paper is meant to show that an interline Current Flow Controller (CFC) is able to reduce the operating costs of hybrid AC/DC meshed grids by alleviating the congestion within the DC lines. The work considers a ... -
