New Relay Protection Measures for Distribution Networks
This paper proposes a relay protection scheme based on random forest algorithm, combined with IoT technology for real-time data collection and processing, to improve the sensitivity and accuracy of relay protection. By constructing a simulation model of a distributed power generation system, we compared and analyzed the performance of traditional fixed threshold. 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.

New Optical Fiber Communication Technologies Optical Solitons
Optical solitons are self-reinforcing solitary waves that maintain their shape over long distances as they propagate through optical fibers. They arise from a delicate balance between the nonlinear effects and the dispersive effects in the fiber. Mathematically, the behavior of optical solitons can. This paper reviews the discovery of the optical soliton and historical attempts of its applications in ultra-high-speed communications.
