Intermittency of renewable energy sources can cause greater frequency variations and with no other intervention, the generation reserve capacity of a power system needs to be significantly increased to ensure frequency stability, resulting in increased costs. With appropriate control actions, proton exchange membrane electrolyzers (PEMELs) can be used to regulate power system frequency stability, but their adjustable demand-side response capabilities need to be investigated. This article first introduces the dynamic characteristics of the PEMEL stack to examine the impact of incorporating the ...

Information flow topology is crucial in the control of connected autonomous vehicles. It has a substantial influence on the platoon's performance, especially in scenarios with imperfect communication. To address this issue, this study provides a real-time switching topology technique for improving the platoon's performance under various types of imperfect communication situations and constant packet dropout rates. First, a discrete sliding mode controller with a double power reaching law is designed for a nonlinear heterogeneous vehicle dynamic model with packet loss. Then, Lyapunov ...

This research article presents an adaptive auto-reclosing scheme to preserve the network stability in post-fault scenarios for the power grids equipped with synchronous-based distributed generations (SBDGs). Based on the precise fault location information, the proposed adaptive reclosing strategy will classify all the fault events in either reclosing or block reclosing zones. Furthermore, the proposed intelligent auto-reclosing scheme will ensure safe and stable network operation by preventing hazardous futile reclosing attempts against persistent faults in forestry or densely populated areas ...
