The increased integration of distributed energy sources into microgrids presents a major challenge in voltage and frequency stability of the microgrids, especially in islanded conditions. Microgrid control is typically classified into a three-level hierarchical control involving primary, secondary, and tertiary control, where primary and secondary levels are related to the operation of a microgrid...
With the advance of power electronic technology, the application of HVdc light systems based on voltage-source insulated gate bipolar transistor (IGBT) converters has increased rapidly in renewable, microgrid, and electric power systems. This paper proposes an optimal control strategy for an HVdc light system using a direct current vector control mechanism. The proposed approach is compared with the...
