Voltage stability in future power systems

This article discusses challenges that future power systems will pose in terms of voltage stability. The focus is on the impact of the proliferation of new technological solutions. Major factors impacting voltage stability, the need for their modeling and new simulation tools are discussed including interdependency of the future power systems and other infrastructures. Probabilistic voltage security assessment to deal with increase in uncertainties is suggested. Distributed control architecture and hierarchical control for coordination are discussed and suggested as control architectures of future power systems. Synergy with developments in relevant research and engineering fields are shortly elaborated.
