Modeling and Control of a Multi‐Energy Microgrid With Wind LVRT and Battery Pre‐Synchronization Strategy

Energy Science &Engineering, Volume 14, Issue 1, Page 266-280, January 2026.
This study establishes a hybrid microgrid model integrating a Doubly Fed Induction Generator (DFIG), a photovoltaic (PV) array, and a battery energy storage system, and proposes a coordinated control framework. The DFIG regulates DC‐bus voltage through the grid‐side converter and performs maximum power tracking via the rotor‐side converter, while the ...

Damping Torque Analysis of Power Systems with DFIGs for Wind Power Generation [PDF]

, 2016
A grid-connected DFIG for wind power generation can affect power system small-signal angular stability in two ways: by changing the system load flow condition and dynamically interacting with synchronous generators (SGs).

Dynamic Equivalent Model of Two‐Staged Distributed Photovoltaic Cluster Based on Multiple Clustering Algorithms

IET Circuits, Devices &Systems, Volume 2026, Issue 1, 2026.
Aiming at the modeling problem of bipolar distributed photovoltaic (DPV) cluster, this paper proposes a clustering equivalent modeling method based on clustering algorithm. First, by analyzing the detailed model of bipolar DPV, it is found that the indexes that can reflect its steady‐state and dynamic characteristics mainly include energy storage ...

Performance Improvement of PMSG‐Based Wind Energy Systems via Sensorless FS‐Predictive Current Control With MRAS and MPPT‐OTC Integration

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This paper proposes a hybrid sensorless control strategy for a permanent magnet synchronous generator (PMSG)‐based wind energy conversion system (WECS). The approach integrates finite‐set predictive current control (FS‐PCC), a model reference adaptive system (MRAS) estimator and an optimal torque control maximum power point tracking (MPPT‐OTC) method ...
