A Generic Voltage Control for Grid-Forming Converters With Improved Power Loop Dynamics

چکیده

Grid-forming converters (GFMCs) provide voltage support and other grid services, such as inertia droop, in more-electronics power systems. The GFMCs with small droop coefficients or connected to the through a impedance may have fast loop, which leads serious conflicts inner ac control resulting oscillations even instability. To address this problem, an extremely loop should be expected for GFMCs. On top of that, must operate well both stand-alone grid-tied conditions. Through detailed analysis, article first reveals that operation dual-loop controlled GFMC LCL output filter features much slower than mode. improve dynamics GFMCs, we propose generic scheme high-pass current feedback loop. controller has tracking performances under operations, thereby enabling achieve better regulation service. improvements are verified via experiments.

Low Voltage Ride Through Enhancement Based on Improved Direct Power Control of DFIG under Unbalanced and Harmonically Distorted Grid Voltage

In the conventional structure of the wind turbines along with the doubly-fed induction generator (DFIG), the stator is directly connected to the power grid. Therefore, voltage changes in the grid result in severe transient conditions in the stator and rotor. In cases where the changes are severe, the generator will be disconnected from the grid and consequently the grid stability will be attenu...

Sliding-Mode-based Improved Direct Active and Reactive Power Control of Doubly Fed Induction Generator under Unbalanced Grid Voltage Condition

This paper proposes an improved direct active and reactive power control (DPC) strategy for a grid-connected doubly fed induction generator (DFIG) based wind-turbine system under unbalanced grid voltage condition. The method produces required rotor voltage references based on the sliding mode control (SMC) approach in stationary reference frame, without the requirement of synchronous coordinate...

Reactive Power Sharing and Harmonic Voltage Modification in Single Phase Island Micro-Grid with Drop Control

Abstract: When several parallel inverters are in islands operating mode, the droop control scheme is usually used to control the inverters. The droop control method enables the inverters of a Micro-Grid to control the voltage and frequency of the network in a decentralized regulation behavior. The drop control method also enables the inverters to share the required active and reactive powers of...
