Study on Smart Grid System Based on System Dynamics
Indonesian Journal of Electrical Engineering and Computer Science, 2014Co-Authors: Cui Rui, Xu PengAbstract:Smart Grid is a Large Complex System, involving generation, transmission, distribution and delivery of four links. This paper analyzes the structure of the smart grid System in depth with a combination of qualitative and quantitative research approach. Then it explains state variables, rate variables and constants in the development of smart grid System under the Vensim software environment and analyzes subSystems causal feedback relationship in a macro point of view. Finally, this paper analyzes the simulation on the amount of funding and professionals in the smart grid System dynamics flow diagram after inputting DYNAMO language equations. The simulation analysis shows that the development of the smart grid should focus on training professionals. Professional talent is a source of strength in the smart grid development. At the same time, we should also pay attention to industrial policy related to the smart grid and seek break under the guidance of policy.

an optimal allocation model for Large Complex water resources System considering water supply and ecological needs
Water, 2019Co-Authors: Yaogeng Tan, Zengchuan Dong, Chuansheng Xiong, Zhiyu Zhong, Lina HouAbstract:Water resources are very important to support the socio-economic development and maintain environmental health, which is a typical issue in water resources management. In this study, we developed an optimal allocation model for a Large Complex System of water resources by considering both water supply and river ecological benefits. The water supply benefit is defined as the minimum water deficit for different water users, while the ecological benefit involves making the reservoir release as close as possible to the natural streamflow. To solve this problem, the combination of decomposition-coordination (DC) and discrete differential dynamic programming (DDDP) methods were proposed. The proposed methods first decomposed a Large System with multi-objective programming into subSystems, and the optimal solution of each subSystem was accomplished by the DDDP method to solve the System efficiently. Then the subSystems’ solutions were coordinated to figure out the near global optimal solution. The proposed models were tested in the Lingui and Yongfu County, Guilin City in China. Results show that the optimal reservoir release is close to the natural flow regime and there is a slight water deficit ratio in both level years. The water supply objective is more sensitive to the System model compared with the ecological objective, and the result of water allocation is optimized when the reservoir release is as close as possible to the natural flow based on the minimum water deficit. The proposed System model could facilitate sustainable water use and provide technical support for water resources management in economic development.

paradigm shift in urban energy Systems through distributed generation methods and models
Applied Energy, 2011Co-Authors: Massimiliano Manfre, Paola Caputo, Gaia CostaAbstract:The path towards energy sustainability is commonly referred to the incremental adoption of available technologies, practices and policies that may help to decrease the environmental impact of energy sector, while providing an adequate standard of energy services. The evaluation of trade-offs among technologies, practices and policies for the mitigation of environmental problems related to energy resources depletion requires a deep knowledge of the local and global effects of the proposed solutions. While attempting to calculate such effects for a Large Complex System like a city, an advanced multidisciplinary approach is needed to overcome difficulties in modeling correctly real phenomena while maintaining computational transparency, reliability, interoperability and efficiency across different levels of analysis. Further, a methodology that rationally integrates different computational models and techniques is necessary to enable collaborative research in the field of optimization of energy efficiency strategies and integration of renewable energy Systems in urban areas. For these reasons, a selection of currently available models for distributed generation planning and design is presented and analyzed in the perspective of gathering their capabilities in an optimization framework to support a paradigm shift in urban energy Systems. This framework embodies the main concepts of a local energy management System and adopts a multicriteria perspective to determine optimal solutions for providing energy services through distributed generation.
