Summary
The article proposes a novel framework for accelerating Electromagnetic Transient (EMT) simulations in power systems by replacing computationally expensive components with Physics-Informed Neural Networks (PINNs). The proposed PINN formulation enables a modular and scalable integration into the simulation algorithm, leading to significant speedups. The authors demonstrate a 4-6x simulation speedup using a type-4 wind turbine EMT model.

Summary
This article proposes a dynamic power allocation method for NOMA-based transmission in 6G optical wireless networks. The proposed method uses a combination of RF-aided grouping and dynamic power allocation to maximize the sum rate, fairness, and energy efficiency of the network. The results show that the proposed method converges to the optimum solution and outperforms existing schemes.
