Comparative Analysis of Sub-Synchronous Oscillations With Various Grid-Forming Control Schemes Under Series-Compensated Line

IEEE Access
This paper presents a comparative study of various grid-forming control strategies under different series compensation levels to suggest the optimal control scheme for compensated lines. Series compensation is a technique used to insert a fixed capacitor

Tailoring Iron Nanostructures on MoS2: The Pivotal Role of Sulfur Vacancies in Growth Morphology and Charge Transfer

Advanced Materials Interfaces, EarlyView.
The deposition of Iron on pristine MoS2/Au(111) monolayers produces nanoparticles that donate charge to the support, generating Fe+2‐interfacial species. On the contrary, on defect‐engineered MoS2, sulfur vacancies trap sub‐nanometric Fe clusters and host two excess electrons that redistribute locally, suppressing Fe oxidation without formal Mo ...

Non-Intrusive Battery-Backed Grid-Forming Configuration for Grid-Following Photovoltaic Plants Retrofit

Energies
Existing grid-connected photovoltaic (PV) systems with grid-following (GFL) control rely on phase-locked loop (PLL)-based grid synchronization, which may become unstable under weak grid conditions.

Control strategy for seamless transition from islanded to interconnected operation mode of microgrids

Journal of Modern Power Systems and Clean Energy, 2017
Microgrids can operate either interconnected to the utility grid or disconnected forming an island. The transition between these modes can cause transient overcurrents or power oscillations jeopardizing the equipment safety or the system stability.

Output Impedance Control Method of Inverter-Based Distributed Generators for Autonomous Microgrid

Energies, 2017
The droop method is the most favorable alternative in microgrid implementations for autonomous control of grid-forming inverter-based distributed generators (DGs) connected in parallel. However, the dynamic characteristic of the conventional droop method
