Small Structures, Volume 7, Issue 6, June 2026.We successfully synthesized Al‐LLZO and fabricated and optimized various contents of HSE. Unlike BE + HSE, the combination (CE) of Al‐LLZO and BE facilitated the formation of a Li+ transport network by evenly distributing Al‐LLZO throughout the cathode, minimizing interfacial resistance. This demonstrates the excellent electrochemical performance of CE‐

A Control Strategy for Variable Speed Condenser Based on Doubly‐Fed Machine
IET Smart Energy Systems, Volume 2, Issue 2, Page 120-130, June 2026.This paper proposes a variable speed condenser (VSC) control strategy based on a doubly fed machine. It can be installed in PV stations and wind farms to enhance the grid‐connection performance of renewable energy power plants. ABSTRACT The lack of active power support capability in power systems with large‐scale renewable energy integration has become
