Urban Power Grid Resilience Enhancement with HVDC Intertie

Urban power grid, HVDC intertie, capacity expansion, resiliency enhancement

Resilience is a critical aspect of urban power grid development and modernization. VSC-HVDC intertie solutions offer advanced technology options with integrated system benefits including flexible power flow, dynamic voltage support, emergency power control, and black-start capability. The focus of this paper is on urban power grid resiliency enhancement through emergency power control features of VSC-HVDC intertie under severe system disturbance conditions. The proposed emergency power controller (EPC) performs real-time network condition assessments and activates appropriate grid support functions to reduce the impacts of the disturbances and mitigate the risk of spread outages. Simulation studies are performed using a realistic urban power system.
