ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

ABSTRACT The focus on wind power frequency regulation has largely been on individual wind farms, which presents challenges in meeting the coordinated operation needs of multiple stations within large‐scale installations. To address issues of model simplification and accuracy, we propose a large‐scale wind farm equivalent modeling method based on ...

A modified line voltage stability index (MLVSI) is proposed to address limitations in the existing indices. The MLVSI is evaluated against Lmn, MVSI, and NCPI under varying load levels, renewable energy penetration, and contingency scenarios. It considers line resistance, power flow direction, and high‐loading events to identify critical lines and ...
