Parameter identification of PLL for grid‐connected inverter based on parameter sensitivity analysis

IET Power Electronics
Under the condition of weak grid, the phase‐locked loop (PLL) is one of the main reasons for the sub‐synchronous oscillation of the grid‐connected inverter.

Control of transient power during unintentional islanding of microgrids [PDF]

, 2014
In inverter-based microgrids, the paralleled inverters need to work in grid-connected mode and stand-alone mode and to transfer seamlessly between the two modes. In grid-connected mode, the inverters control the amount of power injected into the grid. In

Grid-connected inverter fault diagnosis in closed loop

Dianzi Jishu Yingyong, 2019
At present, the fault diagnosis method for the grid-connected inverter is mainly applied to the open-loop system, and the actual grid-connected inverter is mostly a closed-loop control system. Therefore, for the grid-connected inverter in the closed-loop

Passive P-Control of a Grid-Connected Photovoltaic Inverter

IFAC Proceedings Volumes, 2008
A passive P-controller for a single-phase single-stage grid-connected photovoltaic inverter is presented. Explicit dependance of the PV array parameters on external unpredictable variables such as temperature and solar irradiance is avoided by extending the control scheme with a reference estimator.

Phosphorylation‐Facilitated CKB Lactylation At K11 By GCN5 Enhances Creatine Kinase Activity and Mitigates Neuronal Damage After Cerebral Ischemia‐Reperfusion

Advanced Science, EarlyView.
This study uncovers hierarchical coordination between K11 lactylation and S199 phosphorylation of CKB in cerebral ischemia‐reperfusion injury. Such dual modifications potentiate CKB enzymatic function, remodel energy metabolism, alleviate oxidative stress and neuronal damage, and represent a viable therapeutic target for stroke treatment.
