An Information-Theoretic Approach to PMU Placement in Electric Power Systems
TL;DR: A greedy PMU placement algorithm is proposed, and it is shown that the performance is the best that one can achieve, in the sense that it is NP-hard to achieve any approximation ratio beyond (1-1/e) .
Protection of microgrids with a high penetration of inverter-coupled energy sources
TL;DR: In this paper, a current limitation method for the inverters is discussed, which is necessary to avoid inverter disconnection during faults, and a method to determine the type of fault is described.

Joint optimization of high-speed train timetables and speed profiles: A unified modeling approach using space-time-speed grid networks
TL;DR: This research aims to systematically integrate problems of macroscopic train timetabling and microscopic train trajectory calculations by developing a unified modeling framework using three-dimensional space-time-speed grid networks to characterize both second-by-second train trajectory and segment-based timetables at different space and time resolutions.
