  • Power Quality Relay Protection for Distribution Networks

    Power Quality Relay Protection for Distribution Networks

    This Special Issue aims to explore the optimization of relay protection strategies used in power distribution networks, focusing on the integration of control and monitoring technologies to improve overall system reliability and efficiency. Distribution system operators (DSOs) must ensure a delicate balance between maintaining system stability and accommodating the diverse interests of stakeholders, including independent power producers (IPPs) and end consumers, who demand an uninterrupted power supply with high-quality parameters. Selective short-circuit protection can be achieved in different ways, such as: Time-graded protection Time- and current-graded protection A. This paper proposes a relay protection scheme based on random forest algorithm, and uses IoT technology for real-time data collection and processing.
