Output Power Variation and Mismatch Losses of Photovoltaic Power Generators Caused by Moving Clouds

, 2019
Photovoltaic (PV) systems are affected by irradiance fluctuations, mainly caused by overpassing cloud shadows, suffering from fluctuating output power. With high PV penetration levels, these fluctuations can lead to power system instability and problems in power quality.

A Novel Thermoelectric Generation Array Reconfiguration to Reduce Mismatch Power Loss Under Nonuniform Temperature Distribution

International Journal of Energy Research
In practice, industrial exhaust emissions as well as emissions from automobiles, ships, biomass combustion, etc., can be potential application areas for thermoelectric generation (TEG). However, the structural design of heat exchange equipment is usually limited by the internal flow field, resulting in uneven temperature distribution on the heat ...

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

Advanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...
