Methods for voltage and power stability analysis of emerging HVDC system configurations

Voltage and power stability in HVDC systems have traditionally been studied for simplified system models using analytical methods based on quasi-static assumptions. However as usage of direct current transmission increases, new system configurations, the corresponding need for new analytical tools, and new concerns about adequacy of system modeling have emerged. In this paper these emerging issues and needs are discussed and new analytical methodologies that could potentially meet those needs are presented in a single framework.
