Research on Comprehensive Evaluation and Early Warning of Transmission Lines’ Operation Status Based on Dynamic Cloud Computing

open access: yesSensors, 2023
The current methods for evaluating the operating condition of electricity transmission lines (ETLs) and providing early warning have several problems, such as the low correlation of data, ignoring the influence of seasonal factors, and strong ...

Modeling simulation and inverter control strategy research of microgrid in grid-connected and island mode

open access: yesEnergy Reports, 2022
Under the “double carbon” goal, distributed generation (DG) with inverters will show an explosive growth trend. The microgrid can operate in different modes as a channel for DG to connect to the main grid.

Joint distribution of spins [PDF]

open access: yesDuke Mathematical Journal, 2021
We answer a question of Iwaniec, Friedlander, Mazur and Rubin on the joint distribution of spin symbols. As an application we give a negative answer to a conjecture of Cohn and Lagarias on the existence of governing fields for the $16$-rank of class groups under the assumption of a short character sum conjecture.

Interoperability Testing of a Smart Home Automation System under Explicit Demand Response Schemes

open access: yesEnergies, 2022
Interoperability becomes a key issue for smart grid systems, as the interaction between diverse components needs to lead to a normal system operation. In this paper, we test interoperability issues with respect to home automation.
