Abstract

This article investigates the required modifications to droop control design for optimum operation of Multi-Terminal High-Voltage Direct Current (MTHVDC) systems during line and converter outages. A typical 6-bus MTHVDC system is used in this study. Different scenarios are considered during the design process such as different outage types, violation of power ratings of system components, and variability of wind power injected into the system. A variable droop control gains technique is proposed to ensure minimum power loss and maximum annual energy collection. The study is extended to investigate the effect of employing constant droop control gains calculated during rated conditions on the system performance. Moreover, the results of the constant and the proposed variable droop gain schemes are compared. Simulation results show the effectiveness of the proposed techniques for designing optimum droop gains during abnormal conditions. Additionally, general guidelines are presented for the implementation of the proposed techniques.
