Title:  Data-Driven Techniques for Subsynchronous Oscillation Localization and Mitigation in Wind-integrated Power System

Abstract: The commitment made by China at the 75th United Nations General Assembly to achieve 'carbon peaking ' and 'carbon neutrality' has elevated the development of clean energy to a new strategic level. The harnessing and utilization of wind energy have emerged as a crucial strategy in the national energy revolution. Wind power has become an integral component of the power system, and its penetration rate is expected to increase significantly.
Subsynchronous Oscillation (SSO) is a prominent stability issue in wind-integrated power systems, characterized by multiple sources, diverse modes, time-varying frequencies, and intricate influencing factors. Several incidents of SSO have been reported in wind farms located in various regions, including Texas and Buffalo Ridge in the United States, Gu Yuan area in North China, Hami region in Xinjiang, and Nan'ao in Guangdong, China. SSO incidents may result in damage to renewable energy equipment, widespread disconnection of renewable energy sources, fatigue in the shaft system of thermal power units leading to generator shaft fractures, or even trigger converter tripping, causing the shutdown of HVDC systems. In extreme cases, it can lead to cascading failures and major power outages. These pose a significant threat to the safe and stable operation of wind-integrated power systems and require heightened attention. This report primarily outlines the research advancements achieved by our research team in the domain of data-driven techniques for subsynchronous oscillation localization and mitigation in wind-integrated power systems.
