综合能源系统的动力学模型及规划、运行基础理论研究

以分析力学为基础，综合热力学、电网络、传热学、流体网络多学科的理论，基于公理化思想构建完善的能量网络理论。基于能量传递、转换和储能单元的物理特性建立普遍化集中参数模型，提出兼顾能量和能质(㶲，指当系统由任意状态可逆地变化到与给定环境相平衡的状态时可转换为其他形式的部分能量)的含多种能量形式的综合能源系统统一建模理论，建立能量网络方程并研究高效求解方法，通过物理实验验证其正确性。深入研究综合能源系统中能量和㶲的动力学行为及时空分布特征，将传热学中的热量传递能力(火积)概念推广到包括多种能量形式的广义(火积)，以描述各类设备传递能量的能力。借鉴㶲经济学原理，建立综合能源系统优化性能评价方法，提出其优化规划和优化运行的理论与方法，开发优化规划与分析评价软件并应用于多个实际工程。项目拟从根本上解决综合能源系统的物理机理及建模、分析问题，以按能源品位梯级综合利用为主线思路，为其规划、运行奠定基础。

Based on analytical mechanics, and by synthesizing multidisciplinary theories of electric network, thermodynamics, heat transfer and fluid network, the axiomatized energy network theory will be established. The generalized lumped parameter models of energy transfer, conversion and storage units will established based on analysis of their physical characteristics, and the unified modeling theory for multi-energy networks (integrated energy systems) considering both quantity and quality of energy will be formed (Exergy will be used to evaluate the quality of energy, which means the part of energy which can be converted into any other energy form when the system is reversibly changed from any state to the state balancing with a given environment). The efficient solution methods for the energy network equations will be proposed. The correctness of the energy network theory will be verified by physical experiments. The dynamic behavior and temporal/spatial distribution characteristics of energy and exergy will be discussed, and the concept of entransy in heat transfer is extended to the generalized Entransy considering various energy forms to describe the energy transfer ability of various devices. The value evaluation methods of integrateded energy systems will be set up based on principles of exergy economics, and the theories and approaches for optimal planning and operation will be established. The software of optimal planning, ananlysis and evaluation will be developed and applied to different practical engineering projects. The project intends to solve the problems of fundamental physical mechanism, modeling and analysis of integrated energy systems and lay a solid foundation for their optimal planning and operation according to energy grade based comprehensive utilization.
