Gaoya dianqi, 2018 当低压微电网由并网过渡到孤岛运行时会出现功率缺额的现象,导致微电网无法保持电压和频率稳定。文中提出了双重下垂控制的策略,即在改进耦合下垂控制同时,又增加一层对于直流总线电压响应的下垂控制。该控制策略能够在这孤岛模式和并网模式下工作,实现自动调节微电源的输出功率。此外,该控制策略还解决了孤岛模式和并网模式之间的切换不平滑的问题。对提高微电网的电能质量和供电可靠性具有重要意义。以上所提出的控制策略通过MATLAB仿真验证其有效性。

International Journal of Applied Linguistics, EarlyView.ABSTRACT This computational linguistic study analyzes 8743 Rednote posts to examine how sentiment, emotion, and content domain collectively shape social comparison dynamics on social media. We identify four key findings: (1) an emotional gradient, where upward comparison content exhibits the highest sentiment scores and downward comparison the lowest; (

International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines how foreign language teachers’ beliefs about the medium of instruction and translanguaging evolve over time by revisiting three in‐service teachers twelve years after their initial interviews. Using a qualitative longitudinal design, the study traces how translanguaging was initially framed as pedagogically deficient but ...
