This study explores fault diagnosis methods for PWM inverters in a wind energy conversion system using a doubly fed induction generator. Two intelligent diagnostic techniques, fuzzy resonant logic and artificial neural networks, are proposed. The fuzzy logic method monitors inverter faults in real time, whereas the neural network method uses 3D feature

This paper proposes a time‐varying inertia estimation framework based on sensitivity‐guided clustering and aggregation. It can achieve high‐accuracy inertia estimation with limited measurements, reducing the relative error by nearly 10% compared with existing methods, and exhibit strong robustness to noise and disturbances.

Based on the characteristic of wind turbine LVRT influencing system power balance, this study proposes a method utilising active LVRT control to achieve transient stability. A transient stability control strategy is developed by integrating active LVRT with deep reinforcement learning while introducing a disturbance‐level‐based coordinated control ...

In the paper, first, the modelling of a power system with a Permanent Magnet Synchronous Generator (PMSG), Unified Power Flow Controller (UPFC) and Doubly‐Fed Induction Generator (DFIG) is fully considered. Next, the possible candidate control law and its implementation technique on the power network are examined.

A GEDMM is proposed to represent the MIWPS as multiple VSISs and model each of them as the VTDS2M whose unknown parameters are identified with the proposed hybrid optimized square root cubature Kalman filter (HOSRCKF). To solve the issues that the physical meanings of existing short circuit ratios (SCRs) are unclear and the critical values of existing ...

Preventive Control Considering Stability Constraints for Repeated Low Voltage Ride Through Events
This paper proposes a voltage stability preventive control strategy that accounts for repeated low‐voltage ride‐through characteristics. The method first partitions the system and constructs a short‐term voltage stability assessment index that effectively incorporates repetitive LVRT events, while offline generating a corresponding set of anticipated ...

Cyber‐Resilient MMC‐MTDC Stability via Robust Observer Design for Wind‐Integrated Grids
This paper proposes a stochastic stabilising control method, based on a Markov jump model (MJM), to comprehensively address stability challenges in modular multilevel converter‐based multi‐terminal direct current (MMC‐MTDC) systems due to communication network disturbances.
