Novel Real-time Voltage/Frequency Indexes for Measuring Energy Resilience in Navy Microgrids
Abstract
Microgrids provide the Navy s electric infrastructure with the high power density it requires to achieve mission success, and energy resilience is one of the most critical requirements. The frequency of extreme events (e.g., hurricanes, earthquakes, and floods), faults, and man-made attacks (i.e., cyber and physical attacks) has increased dramatically, affecting the energy resilience of DoD microgrids from long outages to major equipment damage. The energy resilience of microgrids has been defined in a number of ways, butthese metrics cannot be monitored in real-time, are often design specific and cannot be applied to multiple designs of microgrids, nor can they provide information on how microgrid resilience deteriorates over time. To accomplish this, a standardized methodology from a basic research perspective needs to be developed for the assessment of the performance and health of the Navy s electrical infrastructure, including the installations energy or operational energy platforms. As part of this project, we aim to develop novel voltage and frequency resilience metrics that will be used to assess the health and performance of the Navy s electrical infrastructure (operational platforms and installations). Using the proposed real-time voltage and frequency resilience metrics, it is possible to evaluate the resilience of multiple microgrid design concepts objectively, and the deterioration of the resilience of an existingmicrogrid over time can be determined by tracking the proposed resilience metrics in real-time. The proposed voltage and frequency resilience metrics can be used in combination with a real-time probabilistic resilience assessment framework to predict and assess microgrid resilience in installations energy or operational (manned and autonomous) platforms when they encounter high-impact low-frequency events or are subjected to man-made outages.
