Optimal operation of integrated energy system including power thermal and gas subsystems

《能源前沿（英文）》 2022年第16卷第1期页码 105-120 doi: 10.1007/s11708-022-0814-z

摘要： As a form of hybrid multi-energy systems, the integrated energy system contains different forms of energy such as power, thermal, and gas which meet the load of various energy forms. Focusing mainly on model building and optimal operation of the integrated energy system, in this paper, the dist-flow method is applied to quickly calculate the power flow and the gas system model is built by the analogy of the power system model. In addition, the piecewise linearization method is applied to solve the quadratic Weymouth gas flow equation, and the alternating direction method of multipliers (ADMM) method is applied to narrow the optimal results of each subsystem at the coupling point. The entire system reaches its optimal operation through multiple iterations. The power-thermal-gas integrated energy system used in the case study includes an IEEE-33 bus power system, a Belgian 20 node natural gas system, and a six node thermal system. Simulation-based calculations and comparison of the results under different scenarios prove that the power-thermal-gas integrated energy system enhances the flexibility and stability of the system as well as reducing system operating costs to some extent.

Wen-ming Han,Shui Yu,Hong-yan Zhao,Yang Zhao,Liang Chen

《工程管理前沿（英文）》 2016年第3卷第4期页码 314-320 doi: 10.15302/J-FEM-2016050

摘要： Deepwater offshore area, with rich oil and gas resources, has currently become the hot area for oil and gas exploration and the main battlefield where global oil majors compete with each other. This article summarizes the current situation of deepwater oil and gas exploration and development overseas from the perspectives of exploration history, exploration achievements and technical progress, and analyzes the difficulties and challenges faced by the industry, such as low level understanding of hydrocarbon accumulation conditions, global security and environmental challenges. And then, several feasible implementation strategies have been proposed on how to actively deal with the challenges, promote Chinese oil companies’ overseas exploration, and realize efficient exploration and development of deepwater oil and gas fields overseas. These strategies consist of three aspects: profit-oriented operation principle, exploration ideas supported by theory and technology, and exploration strategy that puts safety first. In the era of low oil prices, Chinese oil companies must build up confidence, seize the opportunity and face the challenge while taking efforts to innovate technologies and theories, updates strategic ideas, and cultivate deepwater talents so as to be in an active position in global deepwater exploration and development industry in the future.

基于紧缩McCormick方法的热电联合系统优化调度策略 Article

邓莉荣, 孙宏斌, 李宝聚, 孙勇, 阳天舒, 张璇

《工程（英文）》 2021年第7卷第8期页码 1076-1086 doi: 10.1016/j.eng.2021.06.006

摘要：

质量流量可调的热电联合系统可以提高能源系统的灵活性、经济性和可持续发展能力。但是，考虑质量流量可调的热电联合系统的优化运行问题是一个高度非凸非线性的问题，主要体现在热力网络模型中的双线性项，即质量流量和节点温度的乘积。现有的方法，如非线性优化、广义Benders分解方法和凸松弛技术等，在求解质量和计算性能上仍然存在不足。为了解决这一问题，本文首先建立了基于质量-流量调节的区域供热网络的基础模型，并通过等效变换和变量代换对基础模型进行了重构。该重构模型减少了非凸约束和双线性项，而且在不失去最优性的前提下，加快了求解过程。然后，文中分别建立了电力网络模型和能源模型，结合之前构造的供热网络模型，建立起热电联合系统优化调度模型。为了松弛联合调度模型中剩余的双线性项，文中采用McCormick包络的凸松弛方法，得到了联合调度模型的目标函数下界。为了提高McCormick松弛的质量，文中提出了一种紧缩McCormick的方法：首先，采用分段McCormick技术，将双线性项中一个变量的可行域划分为几个不相交的区域，通过求解此优化问题可以选出最优解所在的区域，从而缩小了被划分变量的可行域；然后，提出了一种启发式的边界收缩算法来进一步压缩分段McCormick技术得到的缩小版可行域，并恢复了此最优解附近的可行解。算例分析表明，与原对偶内点法和求得全局最优解的双线性求解器提供的方法相比，本文提出的紧缩McCormick方法能快速求解热电联合运行问题，得到令人满意的兼具最优性和可行性的调度结果。

Integrated Optimization and Management of Mining Engineering—Coordinative Operation and Optimal Management

An-lin Shao,Rui-yu Yin

《工程管理前沿（英文）》 2014年第1卷第2期页码 153-159 doi: 10.15302/J-FEM-2014023

摘要： In the view of engineering philosophy, the mining engineering is a dynamic operating process of ferrous material flow, in which the ferrous material flow is processed orderly through a series of continual coordinated procedures. It is also a process of discarding the dross, selecting the essential, and extracting the original metal. The object of management is to fulfill the multi-objective optimization. The proportion of lean ores in iron ore resources is 82% in the world and even 97% in China but their utilization is very low. Aiming at the bottleneck and weakness of China’s resource development, this paper analyzes and plans the mining engineering system as a whole based on the ideas and methods of system theory and engineering philosophical thinking. And the paper proposes the “grade decision-based multi-system integration” engineering management mode, which considers the relationship between engineering and environment and complies with the natural law. In the mode, the mining engineering, including geologic mining, ore blending, concentration and pelleting, can be viewed as a whole and the geological grade, mined ore grade, feed grade, concentrate grade and feed grade of blast furnace can be considered comprehensively. The mode reflected the overall structural optimization idea, realized the analysis, coordination and optimization among the multiple functions and processes, and thus drove the overall efficient and profit optimization throughout the processing flow. The establishment and the application of the “grade decision-based multi-system integration” mode have solved the lean iron ores exploitation problem and supported the “self-sufficiency” resource strategy.

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.

A Fast Evaluation and Research Method for Exploration Potential of Oversea Basins

Hong-quan Kang,Yun-hua Deng,Huai-cun Jia,Tao Cheng,Bo Bai

《工程管理前沿（英文）》 2016年第3卷第4期页码 338-342 doi: 10.15302/J-FEM-2016052

摘要： Oversea hydrocarbon exploration always faces some problems, such as multiple basin types, different exploration prospects, various exploration degrees, diverse data quantities and geological recognitions. This paper focuses on overseas basins with different exploration degrees and offers a new evaluation system and research method for fast evaluation and risk analysis on hydrocarbon potential. Based on the theory of probability, this new evaluation system evaluates each parameter and core accumulation factor with comprehensive and quantitative assignment, to accelerate geological evaluation. In addition, this paper suggests that source rock evaluation should be the core criterion in screening evaluation of poor-explored basins, and also proposes that both the exploration potential and geological recognition should drive the evaluation for basins with high exploration degrees. This new system and method, which is an effective system for fast basin evaluation, is suggested to be used in oversea evaluation and decision-making objectively, scientifically and efficiently.

Application of a vertex chain operation algorithm on topological analysis of three-dimensional fractured

Zixin ZHANG, Jia WU, Xin HUANG

《结构与土木工程前沿（英文）》 2017年第11卷第2期页码 187-208 doi: 10.1007/s11709-017-0391-0

摘要： Identifying the morphology of rock blocks is vital to accurate modelling of rock mass structures. This paper applies the concepts of directed edges and vertex chain operations which are typical for block tracing approach to block assembling approach to construct the structure of three-dimensional fractured rock masses. Polygon subtraction and union algorithms that rely merely on vertex chain operation are proposed, which allow a fast and convenient construction of complex faces/loops. Apart from its robustness in dealing with finite discontinuities and complex geometries, the advantages of the current methodology in tackling some challenging issues associated with the morphological analysis of rock blocks are addressed. In particular, the identification of complex blocks with interior voids such as cavity, pit and torus can be readily achieved based on the number and the type of loops. The improved morphology visualization approach can benefit the pre-processing stage when analyzing the stability of rock masses subject to various engineering impacts using the block theory and the discrete element method.

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.
