Engineering Reports, Volume 7, Issue 1, January 2025.This paper proposes an improved multilevel inverter, which can be well‐applied in renewable–energy based microgrids to feed the AC loads. The proposed inverter profits from the following advantages: Requires only single DC input source. It can provide 7 or 9 voltage levels at the output.

Solar‐Charged Supercapacitor Powering of Wireless Sensor Network Nodes for Environmental Monitoring
International Journal of Distributed Sensor Networks, Volume 2025, Issue 1, 2025.This work describes a novel strategy for designing and building a solar energy harvester that can continuously and autonomously supply power to wireless sensor nodes for long‐term applications. The system depends on solar‐charged supercapacitors instead of batteries and is designed to require very low solar radiation; for a 12 V 1.5 W rated ...

International Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.Line failures, particularly in the form of N‐1 contingencies, are a significant cause of interruptions in power grids, negatively affecting system reliability. Effective risk‐based contingency analysis (RBCA) is essential in modern power systems to address increasing uncertainties and complexities.
