Due to the changing conditions in power systems caused by decreasing number of conventional synchronous generators, the installation of HVDC+links and simultaneously the large-scale penetration of renewable energy sources, the dynamics and (voltage) stability of future power systems as well as the suitability of emergency controls for voltage critical situations need to be investigated. This projects aims at analysing the impact of increased renewable energy sources penetration and their different control possibilities, advanced active distribution networks control strategies and fast-controllable HVDC converters on overall power system dynamics and stability - in particular long-term voltage stability. Further, control opportunities for the prevention of voltage collapse, e.g., load curtailment or reactive power support of active distribution networks will be simulated in order to estimate their impact on stabilizing fast decreasing bus voltages when faced with these changing grid situation.
