The antimony（Sb） electrode, despite its prevalent use for pH detection in complex environments, suffers from severe potential drift due to poor corrosion resistance, thereby impeding long-term or online applications. Intermetallic compounds show excellent resistance to corrosion and oxidation, presenting a promising avenue for improving the stability of the Sb electrode. Therefore, we fabricate an intermetallic compound-doped Sb electrode by adding various cobalt（Co） contents to improve the stability of the Sb electrode without compromising the inherent pH response. It's observed that the alloy electrode exhibits a significant reduction in surface roughness, corrosion product Sb2O3content, cracks, and Sb exfoliation compared to the pure Sb electrode after the electrochemical tests, and the effect becomes more pronounced as the Co content increases. The electrochemical tests further reveal that the alloy electrode exhibits better corrosion resistance than the pure Sb in various solutions, with the alloy electrode containing 80 at% Sb showing the highest corrosion resistance. Moreover,the alloy electrode containing 80 at% Sb also shows excellent sensitivity and anti-interference ability, high accuracy and reproducibility, low hysteresis, and better long-term stability, especially in seawater. These findings suggest that inexpensive Co doping significantly enhances corrosion resistance, thereby reducing electrode surface alterations and eventually improving the potential stability of pure Sb electrodes without affecting the inherent pH response. Furthermore, the obtained results provide an experimental basis for the long-term operation of the alloy pH electrode in complex environments such as seawater without frequent maintenance.

A robust multi-VSGs coordinated control strategy for distributed secondary frequency regulation in islanded microgrids

引用

Science China Technological Sciences 2025年第3期68卷 335-352页

作者： Jing ZHANG Yong LI Jinjie LIN Sijia HU Yijia CAO Fang LIU Mingmin ZHANG Li HE College of Electrical and Information engineering Hunan University Greater Bay Area institute for innovation Hunan University College of Information Science and engineering Central South University College of Electronic Information and Electrical engineering Changsha University College of Information and Electrical engineering Hunan University of Science and Technology

Islanded microgrids(IMGs) offer a viable and efficient energy self-sustaining solution for distributed resources in remote areas. While without utility grid support, the frequency of IMG is susceptible to mismatches between demand and generation. Moreover, IMGs encounter uncertain and nonlinear load disturbances together with system parameter perturbation,which further compromises frequency stability. To this aim, this paper proposes a robust multi-virtual synchronous generators(multi-VSGs) coordinated control strategy for distributed secondary frequency regulation(DSFR) in IMGs, which exhibits minimal model dependency and avoids reliance on global information. Two critical methods are developed:(1) a robust VSG control framework that incorporates the linear active disturbance rejection control(LADRC) technique, which enables the estimation and effective elimination of uncertain load disturbances and system's parameter perturbations;(2) a novel secondorder consensus algorithm-based control law for robust secondary frequency regulation, which is featured with proper power sharing among different participants, suppressed power oscillation caused by response disparities, and reduced reliance on complex communication system. Building on methods(1) and(2), a novel multi-VSGs coordinated control strategy is proposed, providing a robust solution for IMG's frequency restoration, and its dynamic characteristics are explored in detail. The correctness and effectiveness of the proposal are verified by both simulation and the hardware-in-the-loop(HIL) experiment results across typical scenarios.
