Optimal economic and low‐carbon scheduling in integrated energy system considering multi‐level thermal energy coupling and integrated demand response

Energy Conversion and Economics, Volume 6, Issue 2, Page 83-100, April 2025.
Abstract In integrated energy systems (IESs), thermal energies with different characteristics and efficiencies are typically regarded as having the same thermal energy level, which leads to unreasonable assumptions regarding the thermal energy structure of the system.

Development of a field‐programmable gate array‐based real‐time generic solver for power electronics circuits with arbitrary configurations

High Voltage, Volume 10, Issue 1, Page 47-55, February 2025.
Abstract Using a field‐programmable gate array (FPGA) as the core computational engine, this paper proposes a digital real‐time electromagnetic transient simulator for a generic power electronic system. The LC switching model is employed for constant network conductance representation. The fully paralleled and pipelined design for network solutions and

Research on automatic modulation recognition of shortwave signals in few‐shot scenarios based on knowledge distillation

IET Communications, Volume 19, Issue 1, January/December 2025.
A multi‐information fusion method is proposed for few‐shot modulation recognition, which involves converting I/Q signals into A/P signals and training with a combination of VGG and LSTM network models. An ensemble knowledge distillation approach is employed to streamline the network model, meeting the demands for deploying neural network models on ...
