Metaheuristic Based Solution for the Non‐Linear Controller of the Multiterminal High‐Voltage Direct Current Networks

The purpose of this study is to improve the P-I controllers voltage-source converters (VSC)-based multiterminal high voltage direct-current (MT-HVDC) networks. Since VSCs are non-linear elements MT-HVDC stations, classical optimization methods, which approximately implement linear model optimize VSCs, do not generate optimal results. Therefore, paper presents a novel technique VSC-based grids’ by embedding artificial bee colony (ABC) algorithm. voltage-droop control method employed at on-shore grids ensure active and reactive power balance within During an evaluation, achieved via detailed four-terminal designed in PSCAD/EMTDC, improved results obtained under different dynamic situations such as unbalance wind generation, change load demand side grids, eventual VSC disconnection, respectively.
