The Decomposing and Coordinating Strategies for Environmental-Exergoeconomic Optimization of Energy Systems

按照能量系统 (能量转换系统 )的流及废物流变化特征 ,将系统划分为能量转换主子系统及废物治理子系统 ,在此基础上 ,探讨了废物计价策略 ,并通过环境和经济学的结合 ,提出了同时考虑热力学和经济学和环境三个目标的环境经济优化目标及相应的约束条件 ;同时也提出了能量系统的分解协调环境经济学优化策略 ,在子系统分别优化的基础上协调 ,达到系统全局的优化 .

In accordance with the evolution features of both exergy flows and waste flows within the energy system, the total energy system was divided into two subsystems, namely, the energy_conversion subsystem and the waste treatment subsystem. The cost of waste exergy was studied on the basis of the model established. In view of the various factors concerning both exergoeconomics and the environment, the environmental_economic objectives for optimization and the corresponding constraints were presented by considering the objectives of thermodynamics, economics and environment simultaneously. The decomposing and coordinating strategies for environmental_exergoeconomic optimization of energy systems were also developed. Coordination between the optimal results from two subsystems makes the total system optimized.
