Abstract

The district energy system has realized the effective consumption of new energy and the cascade utilization of energy, and has been widely used in the continuous and in-depth advancement of China's urbanization process. The district energy system is an organic combination of source-grid-load, and in practical applications, its components are usually in a dynamic change process, which has a certain impact on the matching of supply and demand of the district energy system. This article first puts forward the concept of district energy network, and then describes the typical adjustment scenarios of its energy supply nodes, energy consumption nodes and energy pipe network side respectively, and allocates energy resources of the district energy network according to various typical adjustment scenarios of the district energy network. The impact of the strategy is analysed to provide a reference for the economic construction of the regional energy system and the rational and efficient use of energy.
