Comprehensive concept-phase system safety analysis for hybrid-electric vehicles utilizing automated driving functions
… utilizes lateral and longitudinal automated corrective control actions. This paper first outlines a proposed SS process including a cross-functional SS working group procedure, followed by the development of an item definition inclusive of the ADFs and ADAS and an examination of 5 hazard …

An influence model approach to failure cascade prediction
… is important for contingency analysis and corrective control designs to prevent large blackouts. In this thesis, we study an influence model framework to predict failure cascades and try to figure out their underlying pattern in real power systems. A hybrid learning scheme is proposed to …

Enhanced power system resiliency to high-impact, low-frequency events with emphasis on geomagnetic disturbances
… attacks and geomagnetic disturbances (GMDs). Corrective control through generation redispatch is proposed to protect the system from cyber-physical attacks. A modification of the optimal power flow (OPF) is proposed which optimizes the system resiliency instead of the generation cost. For …

Protecting the power grid: strategies against distributed controller compromise
… of collaborating elements for monitoring and control. Distributed controllers play a prominent role in deploying this cohesive execution and are ubiquitous in the grid. As global information is shared and acted upon, faster response to system changes is achieved. However, failure or …

A fast state-estimation-based data integrity threat detection approach for combined AC-DC bulk power systems
… serve their loads. Communications and controls for such combined grids, in particular, have increasingly become more challenging. System disturbances in such combined grids have the potential to cascade and affect much larger portions of the grid. These challenges have only been …

The use of artificial intelligence techniques for power analysis
… expert systems for on-line application in Energy Control Centres (ECC), is reported. The development of expert systems is a continuous process as new knowledge is gained in the field of artificial intelligence and new expert system development tools are built. Efforts are being made for on-line …
