Methodology for online identification of dynamic behavior of power systems with an increased amount of power electronics interface units
A methodology for online and offline dynamic stability assessment
suitable for power systems with high penetration of power electronics interface units is presented in this paper. The increasing penetration of renewable energy resources as well as changing market operations
new types of loads and storage technologies
are causing significant changes to power systems dynamic behavior. Unstable generator groups and generators exhibiting poorly damped oscillatory behavior are identified online
opening the possibility to corrective control actions in order to stabilize the system. Moreover
statistical analysis of the abundant data from simulations provides information on the overall impact of power electronics interface units on system stability.
