Voltage Balancing Method For Single Energy Storage System In Bipolar Dc Microgrid, Laixin Guo, Zhi Li, Lei Xie, Penghui Han

Journal of Electric Power Science and Technology

The development of distributed energy resources brings significant advantages to bipolar DC microgrids. Due to load asymmetry, voltage imbalance may occur between the positive and negative poles of a bipolar DC microgrid. Voltage balancers have therefore been introduced and are generally classified into centralized and distributed configurations. A centralized voltage balancer cannot address voltage imbalance caused by long-distance power lines or terminal loads, while a distributed voltage balancer increases system cost due to the construction of additional facilities. To overcome these drawbacks, energy storage systems can be integrated into bipolar DC microgrids. However, this approach requires separate installation at each …

Evaluation Of Impact Of High-Energy-Consuming Industries On Carbon Emissions And Carbon Market Based On Neural Ode-Cge Model, Chengjun Huo, Xueting Cheng, Jinkui Liu, Peng Zou, Jun Wan, Jia Wu

Journal of Electric Power Science and Technology

High-energy-consuming industries represent the primary source of carbon emissions in China, which makes the reduction of their carbon emissions a critical priority for the country's carbon emission reduction efforts. However, due to the lack of robust carbon emission constraint mechanisms targeting these industries, their motivation for emission reduction remains significantly insufficient. To address this issue, this paper proposes a simulation method that integrates neural ordinary differential equations (Neural ODE) with a computable general equilibrium (CGE) model. Using input-output data from 2022 at the national and provincial levels, this method constructs a baseline scenario and three emission reduction scenarios to assess …

Anomaly Sound Detection Of High-Voltage Shunt Reactors Based On Soft-Constrained Latent Regularized Adversarial Learning, Zhihong Wang, Fuqiang Xiong, Jiawen Zuo, Mingzhu Tang, Jianjun Zhang, Xingyu Tang

Journal of Electric Power Science and Technology

With the widespread application of high-voltage shunt reactors in power systems, abnormal phenomena arising during their operation have attracted increasing attention. In existing latent regularization adversarial anomaly detection (LRAAD) methods, the hyperparameter M imposes a hard constraint on the upper bound of the KL divergence of generator-produced spectrograms, which hampers the model's ability to effectively distinguish normal from abnormal data in the latent space, leading to training instability and degraded anomaly detection performance. To address this issue, this paper proposes a soft-constrained latent regularization adversarial anomaly detection (Soft-LRAAD) method. The proposed method introduces a soft constraint loss to replace the …

Improved Unet++-Based Approach For Multi-State Appliance Load Disaggregation, Gui Gu, Jiangliang Jin, Liangliang Hao, Qisheng Huang

Journal of Electric Power Science and Technology

Nowadays, non-intrusive load disaggregation techniques face two major challenges. First, it is difficult to effectively extract the power characteristics of multi-state appliances in low-power states. Second, the generalization capability of disaggregation models is insufficient. To address these two challenges, an improved Unet++-based approach for multi-state appliance load disaggregation is proposed. First, within the encoder-decoder framework, a parallel-structured encoder is adopted to enhance the parsing capability of complex power signals, while skip connections ensure that the decoder can accurately reconstruct the original signal, thus improving the refinement of the disaggregation. Second, a bidirectional long short-term memory (BiLSTM) module is introduced to …

Rewriting Betrayal: The Political Memory Of Andrei Vlasov And His Russian Liberation Army, Christian N. Adams

Departmental Honors & Graduate Capstone Projects

This study examines the evolving historiography of Andrei Vlasov and the Russian Liberation Army (ROA) from the end of World War II to the post-Soviet era. Drawing on Soviet, émigré, and Western sources, it traces how interpretations of Vlasov’s defection reflected shifting moral and political frameworks in Russia’s collective memory. The analysis demonstrates that portrayals of Vlasov, from Stalinist condemnations to post-Soviet reappraisals, mirror the state’s changing relationship to patriotism, legitimacy, and dissent. By comparing Cold War scholarship with contemporary Russian debates, this paper argues that the Vlasov question endures not because of mere intrigue, but because it embodies the …

Nonenzymatic Glucose Biosensor Based On Selective Reduction Of Silver Ions, Maryam Sarlak, Shankar B. Rananavare

Chemistry Faculty Publications and Presentations

A nonenzymatic conductivity-based glucose biosensor, reported here, designed for potential noninvasive measurement in accessible biofluids such as saliva, sweat, and tears. The sensor exploits a classic Tollens’ silvering process that deposits metallic silver on a sensitized surface via a quantitative, selective reduction of silver ions by glucose. Of the two surface sensitization methods used, the self-assembled bifunctional thiol/silane surfactant yields a more stable and sensitive sensor than tin(II) chloride. The conductometric sensor consists of two spiral interdigitated silver electrodes fabricated by lithography and wet etching. The sensor impedance changes after selective metallic silver deposition between the electrodes. The sensor exhibits …
