Towards Developing Implementable High Altitude Electromagnetic Pulse E3 Mitigation Strategies for Large-Scale Electric Grids

Electromagnetic pulses caused by high altitude nuclear explosions (HEMPs) have the potential to severely disrupt large-scale electric grids. This paper presents some strategies that could be helpful in mitigating the impacts of the longer term HEMP E3 aspects, with a focus on techniques that could be implemented in an energy management system. These include adaptive shedding of load and generation, and transmission level switching. Several visualization techniques are also presented. The approach is shown using a 2000 bus synthetic electric grid.
