Special Issue Information

Dear Colleagues,

Advanced sensors and artificial intelligence (AI) are revolutionizing the condition monitoring of power electronic systems. On one hand, advanced sensors play a crucial role in monitoring the health and performance of power electronic systems. These sensors can detect various parameters such as temperature, current, and voltage, providing real-time data that are essential for predictive maintenance and fault diagnosis. The integration of advanced sensors allows for more accurate and timely detection of anomalies, which can prevent failures and extend the lifespan of systems with power electronics. On the other hand, AI enhances the capabilities of condition monitoring systems by analyzing the vast amounts of data collected by sensors. AI techniques such as machine learning and fuzzy logic can identify patterns and predict potential issues before leading to system failures.

Therefore, the integration of advanced sensors and AI provides a powerful approach to condition monitoring that paves the way for more intelligent and resilient power electronic systems, ensuring the efficient and reliable operation of power electronic systems.

Scope and Topics:

We welcome original research articles, review papers, and case studies on topics including, but not limited to, the following:

Advanced Sensor Technologies: Development and application of novel sensors for monitoring electrical, thermal, and mechanical parameters in power electronic systems.

AI and Machine Learning: Implementation of AI and machine learning algorithms for fault detection, diagnosis, and prognosis in power electronics.

Data Analytics: Techniques for processing and analyzing large datasets from sensors to extract meaningful insights for condition monitoring.

The large-scale integration of renewable energy sources introduces significant uncertainty into modern power systems, posing new challenges for reliable and economical operation. Effective scheduling therefore requires accurate monitoring of uncertainty and efficient handling of nonlinear system dynamics. This paper proposes an optimization-based scheduling method that combines sensor-informed monitoring of photovoltaic (PV) uncertainty with advanced processing of nonlinear hydropower characteristics. A detailed hydropower model is incorporated into the framework to represent water balance, reservoir dynamics, and head–discharge–power relationships with improved accuracy. Nonlinear constraints and uncertainty are addressed through a unified approximation scheme that ensures computational tractability. Case studies on the modified IEEE −39 system show that the proposed method achieves effective multi-source coordination, reduces operating costs by up to 2.9%, and enhances renewable energy utilization across different uncertainty levels and PV penetration scenarios.

The junction temperature (Tj) is a key parameter reflecting the thermal behavior of Silicon carbide (SiC) MOSFETs and is essential for condition monitoring and reliability assessment in power electronic systems. However, the limited temperature sensitivity of switching characteristics makes it difficult for traditional single temperature-sensitive electrical parameters (TSEPs) to achieve accurate estimation. To address this challenge and enable practical thermal sensing applications, this study proposes an accurate, application-oriented Tj estimation method based on multivariate linear regression (MLR) using turn-off current fall time (tfi) and fall loss (Efi) as complementary TSEPs. First, the feasibility of using current fall time and current fall energy loss as TSEPs is demonstrated. Then, a coupled junction temperature prediction model is developed based on multivariate linear regression using tfi and Efi. The proposed method is experimentally validated through comparative analysis. Experimental results demonstrate that the proposed method achieves high prediction accuracy, highlighting its effectiveness and superiority in MLR approach based on the current fall phase characteristics of SiC MOSFETs. This method offers promising prospects for enhancing the condition monitoring, reliability assessment, and intelligent sensing capabilities of power electronics systems. Full article
