In paper, proposed, where grid, solar photovoltaic, CCHP, battery storage systems primary sources. adjunct...
Thermal management of magnetic coils is essential for the safe and stable operation high-power wireless charging systems (WCS). Upon a deficiency detailed thermal analysis, this paper presents model under natural convection featuring both accuracy simplicity. Analysis shows that loss distribution between different parts coil has little effect on resultant temperature. This in context leads to key conclusion maximum allowable power density decreases an m-1/8 relationship with increasing area...
Discrete power devices are used in a wide range of applications some which would benefit from device condition monitoring (CM). This paper presents data-driven method to online evaluate the health status discrete devices. It is based on detection mold temperature by only one thermocouple, offering low cost and non-intrusive features. The approach looks into five electrical stressors uses existing sensors track load variation, enabling adaptation both linear or nonlinear conditions inverter...
Controllable air conditioning loads (ACLs) and distributed renewable energy sources have become one of the research focuses in recent decades. This paper aims to propose a new control strategy which can schedule interruptible ACLs increase photovoltaic (PV) penetration rate distribution network, with battery storage system (BESS) involved scheduling process. The scheme is modelled further transformed into MILP (mixed integer linear programming) problem whose objective function minimise...
A series of bridge overturning accidents in recent years indicates that single-column pier bridges are susceptible to failure. However, the traditional calculation method was incapable ensuring an accurate prediction ultimate capacity, which may lead serious consequences engineering practice. In this work, analytical proposed based on identified failure mechanisms. The forensic survey first carried out two typical cases, and findings surveys were summarized into three modes their...
The loss and heat flux of IGBT module change with package degradation, resulting in the variation case temperature its distribution. Inspired by aging mechanism module, this study performs an online observation for IGBT's time-varying profile collecting multiple points bottom case, which achieves a spatial reconstruction beyond junction track capability. Moreover, can also be obtained thermal performance at steady state. A deep neural network (DNN) based data-driven model is established data...

With the progressive increase in penetration of power devices systems, effective transient thermal management modules (PMs) is essential to ensure reliable operation pulsed applications. This paper customizes a module using phase change material (PCM) and anisotropic graphite (TAG). Compared conventional PCM-integrated (PPM), additional TAG enables higher conductivity improves PCM's utilization under pulsed-power conditions. The simulation results show significant junction temperature...
Thyristor crowbar circuits are a critical component in Static Synchronous Series Compensator (SSSC) protection systems, and lower-capacity thyristors often selected to minimize costs. However, their thermal capacity is limited the heat generated by overcurrent will cause junction temperature rise above limit, leading breakdown of device. A thyristor with lower voltage reduces power consumption for same current flow, resulting less generation, integration phase change material (PCM) into...
Capacitors and semiconductors are the most sensitive components in power converter. Power routing is recognized as a viable software technique to ensure their useful lifetime. However, existing strategies mainly focus on unit level of solid-state transformers (SSTs). To address reliability issue within unit, this study proposes method based harmonic energy control. By actively managing low-frequency ripple current caused by AC/DC stage, distribution SST optimized, achieving aging balance...
