Reliability evaluation of future photovoltaic systems with smart operation strategy

Amir AHADI,Hosein HAYATI,Seyed Mohsen MIRYOUSEFI AVAL

《能源前沿（英文）》 2016年第10卷第2期页码 125-135 doi: 10.1007/s11708-015-0392-4

摘要： This paper investigates a new operation strategy for photovoltaic (PV) systems, which improves the overall reliability of the system as a result of the improvement in the reliability of the critical components. First, a mathematical model is proposed using the fault tree analysis (FTA) to estimate the reliability of the PV systems in order to find the suitable maintenance strategies. The implementations demonstrate that it is essential to employ smart maintenance plans and monitor the identified most critical components of PV systems. Then, an innovative analytical method based on the Markov process is presented to model smart operation plans in PV systems. The impact of smart operation strategy on the PV systems is then evaluated. The objective of this paper is to develop plans for improving the reliability of PV systems. A series of case studies have been conducted to demonstrate the importance of smart operation strategies for PV systems as well as the applicability and feasibility of the proposed method.

Reducing CO emissions from the rebalancing operation of the bike-sharing system in Beijing

《工程管理前沿（英文）》 2023年第10卷第2期页码 262-284 doi: 10.1007/s42524-021-0168-y

摘要： With the development of the bike-sharing system (BSS) and the introduction of green and low carbon development, the environmental impacts of BSS had received increasing attention in recent years. However, the emissions from the rebalancing of BSS, where fossil-fueled vehicles are commonly used, are usually neglected, which goes against the idea of green travel in a sharing economy. Previous studies on the bike-sharing rebalancing problem (BRP), which is considered NP-hard, have mainly focused on algorithm innovation instead of improving the solution model, thereby hindering the application of many existing models in large-scale BRP. This study then proposes a method for optimizing the CO₂ emissions from BRP and takes the BSS of Beijing as a demonstration. We initially analyze the spatial and temporal characteristics of BSS, especially the flow between districts, and find that each district can be independently rebalanced. Afterward, we develop a rebalancing optimization model based on a partitioning strategy to avoid deciding the number of bikes being loaded or unloaded at each parking node. We then employ the tabu search algorithm to solve the model. Results show that (i) due to over launch and lack of planning in rebalancing, the BSS in Beijing shows great potential for optimization, such as by reducing the number of vehicle routes, CO₂ emissions, and unmet demands; (ii) the CO₂ emissions of BSS in Beijing can be reduced by 57.5% by forming balanced parking nodes at the end of the day and decreasing the repetition of vehicle routes and the loads of vehicles; and (iii) the launch amounts of bikes in specific districts, such as Shijingshan and Mentougou, should be increased.

Evaluation of the situational awareness eﬀects for smart distribution networks under the novel

Leijiao GE, Yuanliang LI, Suxuan LI, Jiebei ZHU, Jun YAN

《能源前沿（英文）》 2021年第15卷第1期页码 143-158 doi: 10.1007/s11708-020-0703-2

摘要： As a key application of smart grid technologies, the smart distribution network (SDN) is expected to have a high diversity of equipment and complexity of operation patterns. Situational awareness (SA), which aims to provide a critical visibility of the SDN, will enable a significant assurance for stable SDN operations. However, the lack of systematic evaluation through the three stages of perception, comprehensive, and prediction may prevent the SA technique from effectively achieving the performance necessary to monitor and respond to events in SDN. To analyze the feasibility and effectiveness of the SA technique for the SDN, a comprehensive evaluation framework with specific performance indicators and systematic weighting methods is proposed in this paper. Besides, to implement the indicator framework while addressing the key issues of human expert scoring ambiguity and the lack of data in specific SDN areas, an improved interval-based analytic hierarchy process-based subjective weighting and a multi-objective programming method-based objective weighting are developed to evaluate the SDN SA performance. In addition, a case study in a real distribution network of Tianjin China is conducted whose outcomes verify the practicality and effectiveness of the proposed SA technique for SDN operating security.

Neural Operation Management: A New Avenue for Productive and Military Operations

Qing-guo Ma

《工程管理前沿（英文）》 2014年第1卷第3期页码 304-307 doi: 10.15302/J-FEM-2014039

摘要： An important effect of technological progress is the increasing replacement of manual labor by mental labor in productive and military operations. The variation of the operator’s capabilities in cognition, judgment and decision-making has drawn much attention from operation management researchers. Monitoring and evaluation of these capabilities is especially significant in conditions such as long-time operation, operation with special properties and operation under special circumstances. The military power and economic power are both the key concerns for a nation. The military power depends not only on the weapon system, but also the operators’ capabilities of manipulating the system. Similarly, the economic power is not only dependent on advanced machine system, but also the operational capability of the operators. Thus it has become a hot field of research and practice to monitor and assess the operator’s physiological and psychological states online based on neural measurement technology, and then to give real time intervention, so as to reduce the occurrence of accidents and increase the operation performance.

面向生态的水库群调度——以汉江中下游流域为例 Article

王浩, 雷晓辉, 严登华, 王旭, 吴书悦, 尹正杰, 万文华

《工程（英文）》 2018年第4卷第5期页码 627-634 doi: 10.1016/j.eng.2018.09.002

摘要：

水库群的建设和调度改变了河流的自然流态，对河流生态系统造成了不利影响。本文提出了一种面向生态的水库群调度策略，将河流内不同生态功能所需的生态流量整合到水库群联合调度中，以实现生态流量需求和人类用水需求之间的均衡。该策略耦合了常规优化调度方案和一系列实时生态调度方案。在人类用水需求与生态流量需求冲突较小的时段，水库群调度在保障河流最小流量的前提下采用常规优化调度方案，最大限度地提高人类用水效益。在水库引发的水文改变对河流关键生态功能产生严重影响的时期，水库群调度采用实时生态调度方案，调整下泄流量，从而满足河流生态流量需求。该策略被应用于位于中国汉江中下游流域的一个大型水库群中。模拟调度结果表明，实时生态调度方案保证了河流关键生态功能的生态流量需求，其对人类用水效益的不利影响可通过常规优化调度方案得到部分补偿。本文提出的面向生态的水库群调度策略丰富了考虑生态流量需求的水库群联合调度的理论应用。
