摘要：
This article introduces a distributed finite-time event-triggered (FTET) secondary controller that adjusts the dc voltage reference value in the primary droop control (PDC) for a multiterminal dc transmission system (MTDCTS). It effectively ensures that the average dc voltage of the converters in the MTDCTS converges to the nominal value within a finite time, thereby enhancing the system responsiveness. In addition, the controller optimizes power sharing among converters, enabling each converter to distribute active power according to its respective capacity. The introduced event-triggered mechanism (ETM) conserves communication resources and reduces the load on the communication network. To validate the controller's performance, a five-terminal dc transmission system is constructed using PSCAD/EMTDC. © 2024 IEEE.
