Microgrid Design Toolkit Methodology for Incorporating Extreme Events, Hazards and Fragility Data, and Mitigation Trade-off Analysis for Rural Communities in Puerto Rico

This paper presents a methodology developed to determine the feasibility of incorporating combinations of extreme events, their associated hazards, and the fragility of power system components into a model using the optimization tool Microgrid Design Toolkit (MDT). The methodology leverages the existing features from MDT's islanded mode simulator, Performance Reliability Model (PRM), to create a roadmap that helps users identify if a combination of extreme event, hazard, and component fragilities to hazards can be implemented. Real extreme events data is used to derive probabilistic distributions that can be input for the MDT model. Extreme events such as tropical storms, hurricanes, and earthquakes were matched with their respective hazard, high wind speeds, and peak ground acceleration (PGA) respectively, using the methodology developed. Similarly, fragility curves representing the probability of failure of distribution lines/poles and distributed energy resource (DER) components such as diesel generators, solar photovoitaic (PV) generators, and energy storage were found feasible to incorporate using the developed methodology.
