Inverters in voltage control mode including droop control and virtual synchronous generator (VSG) are promising for interconnecting the renewable energy to the grid, which are both emulating the frequency and voltage regulating functions of synchronous generators through droop method. However, improper transient impact current and reactive power output are observed for inverters in voltage control...
By focusing on Guangzhou's street‐vending policy transformation, this article explores how exclusionary practices of urban politics in China are undermined by those who it seeks to exclude and the progressive political climate that questions the exclusionary framework. The exclusion of street vendors in Guangzhou has been led by the National Sanitary City campaign as a revanchist project. It has been...
In this letter, an improved transmission line model is proposed to investigate contact resistance (CR) in bottom-gate bottom-contact organic thin-film transistors (OTFTs). With the modified model, the CR decreases with the increase of gate voltage, which is a good agreement to experimental results. Further, the CR dependence to thickness, width, and edge angle of drain/source electrode contact has...
