Abstract

The increasing complexity of smart grids and large-scale integration of renewable energy have posed challenges to traditional relay protection systems, including insufficient sensitivity, delayed response, and poor adaptability. This paper explores adaptive improvement pathways for relay protection based on smart grid operational characteristics. Through analyzing adaptive protection principles, information fusion mechanisms, and intelligent algorithms, optimized strategies are proposed for distributed power sources, power electronic devices, and multi-node communication environments. Research demonstrates that integrating artificial intelligence algorithms, online parameter identification, and multi-source data fusion technologies enables dynamic parameter tuning and real-time decision-making for protection systems. Simulation and engineering validation results show that adaptive protection systems exhibit enhanced sensitivity and reliability under complex operating conditions, providing technical support for building intelligent relay protection frameworks.
