A decision-making method for the operation flexibility enhancement of hybrid cascaded MTDC

نویسندگان

چکیده

To enable the integration of large-scale renewable energy, hybrid HVDC technology, which combines technical advantages LCC-HVDC and VSC-HVDC, is being gradually deployed in power grid nowadays. The operation Wu-dong-de Hybrid DC Project Jian-su cascaded MTDC has proved its advantages. However, for simultaneous application different converter station technologies system, control strategies become complex. Issuing appropriate instructions to ensure system stability according operational requirements an issue that cannot be ignored decision-making. Even under abnormal conditions, when topology changes due various failure scenarios, reasonable decision-making precise instruction definitions are required. achieve flexible planning this paper presents a method analyzes strategy combinations selected normal conditions system. In addition, calculating process proposed. Simulation results based on five-terminal PSCAD/EMTDC have verified effectiveness proposed method.
