A framework for disturbance analysis in smart grids by fault injection

With growing complexity of electric power systems, a total number of disturbances is expected to increase. Analyzing these disturbances and understanding grid’s behavior, when under a disturbance, is a prerequisite for designing methods for boosting grid’s stability. The main obstacle to the analysis is a lack of relevant data that are publicly available. In this paper, we present a design and implementation of a framework for emulation of grid disturbances by employing simulation and fault-injection techniques. We also present a case study on generating voltage sag related data. A foreseen usage of the framework considers mainly prototyping, root-cause analysis as well as design and comparison of methods for disturbance detection and prediction.
