Along with our country the importance of energy conservation and environmental protection, build clean, low carbon, environmental protection energy system is on the process of energy development in our country, and the construction of the integrated energy system to achieve this ambitious goal, has very important significance to build integrated energy system can be to coal, oil, electricity, gas and other energy in unified planning, To realize the optimization of energy structure, in this paper, we will briefly introduce the advantages of integrated energy system.
The concept of integrated energy system breaks through the technical, market and management barriers of the traditional energy system, and is a comprehensive energy system with unified planning and dispatching of electricity, gas, heat and cold energy. It is of great significance for promoting the transformation of energy structure and promoting the energy revolution in China. Integrated energy system is bound to become the main form of energy system in the future.
All kinds of typical physical devices and their mathematical models in integrated energy system have not been systematically combed and summarized. At the same time, the theoretical system applicable to the evaluation of comprehensive energy benefits has not been established, and the economic, environmental and social benefits brought by the system are still in the conceptual stage. In this paper, the domestic and foreign related research and exploration on the basis of the basic architecture of the integrated energy system, system model and comprehensive benefit evaluation system theory of domestic and foreign research present situation and the results were analyzed and summarized in this paper, combing the shortcomings of current research and looking forward to the future integrated energy system modeling and the comprehensive benefit evaluation of key research directions and key issues.
At present, the domestic and foreign existing research put forward the energy Internet [5] [6], energy hub, pan can net, etc. Are all forms of expression of integrated energy system, the system of basic physical structure and equipment level, various forms of integrated energy system, including electricity, heat, cold, gas production, transmission, storage and consumption of all kinds of energy equipment.
Classified according to the equipment can carry mass type, integrated energy system in all kinds of equipment can be divided into independent model units and the coupling type equipment, independent model cold/hot/gas/electricity equipment unit to maintain their own peculiar to qualitative properties, there is no coupling between heterogeneous can flow into and complementary utilization, coupling type equipment unit can realize power/heat/gas/cold mutual transformation To use.
The development of integrated energy system can be said to be an important measure for the benefit of the country and the people. Although China is behind the developed countries in Europe and the United States in this respect, with China's continuous investment in energy reform, the integrated energy system will have great achievements in the future.
