Abstract
The multi-energy complementary distributed energy system (MCDES) covers a variety of energy forms, involves complex operation modes, and contains a wealth of control equipment and coupling links. It can realize the complementary and efficient use of different types of energy, which is the basic component of the physical layer of the Energy Internet. In this paper, aiming at the demand of the energy application for towns, a distributed energy system based on multi-energy complementary is constructed. Firstly, the supply condition of the distributed energy for the demonstration project is analyzed, and the architecture of the multi-energy complementary distributed energy system is established. Then the regulation strategy of the multi-energy complementary distributed energy system is proposed. Finally, an overall system scheme for the multi-energy complementary distributed energy system suitable for towns is developed, which provides a solid foundation for the development and promotion of the multi-energy complementary distributed energy system.

Summary
The distributed energy system (DES) is the basic component of the physical layer for the energy Internet, which can realize the complementary and efficient use of different types of energy. By encouraging the construction of E-Energy projects, Germany focuses on the integration of energy and information systems, and adopts digital networks to realize the safe supply, efficient utilization and climate protection of power generation [7]. Aiming at building an intelligent industrial demonstration zone, Guangzhou Mingzhu Industrial Zone has constructed a cooling-heating-electricity-gas distributed energy system to improve energy utilization [9]. This paper comprehensively uses a variety of energy production methods, energy storage equipment and the principle of photothermal and chemical complementarity to construct the urban multi-energy complementary distributed energy system project in Zhangjiakou [11]. An overall scheme of MCDES suitable for towns is proposed, which has laid a solid technical foundation and practical experience for realizing the large-scale distributed energy system
