Energy Network Flow Model and Optimization Based on Energy Hub for Big Harbor Industrial Park

To model and optimize the energy network flow for the energy conservation and emissions reduction in big harbor industrial park by analyzing the characteristics of harbor energy system, this paper presents a universal framework for the modeling of energy systems comprising multiple-energy carriers, such as electricity, heat, gas, etc. The modeling framework is based on the energy hub concept model and the idea of "energy flow network". Then the system optimization to minimize energy consumption with multi-agent distributed control is put forward in this paper, which is executed with parallel processing method. After that, this paper takes Lingang industrial park in Shanghai as an engineering example to verify the whole energy model and optimization method proposed. In conclusion, the proposed approach can realize rational utilization of multiple-energy carriers for reducing energy consumption and carbon emissions, which can enhance the regulation level of energy center and make the energy system of the harbor run efficiently and orderly, that is to say, this paper can provide a technical support for the construction of resource saving and environment friendly harbor.
