Space Energy Internet System

Global Energy Internet is one of the hottest research fields recently. It is a further development and enhancement of the smart grid system. However, the energy Internet is different from the smart grid in several aspects. Energy Internet is a new type of ecological energy system that is integrated with traditional energy system when the information has evolved into a new means of production, especially with the introduction of the concept of energy micro-grid and it change the system and architecture of the traditional smart grid. Energy micro-grid is a distributed energy network system that can achieve efficient energy supply and consumption. In this paper we present a new concept of energy micro-grid such as space energy Internet system. The concept of solar power station is explained and the definition and connotation of space energy Internet system is described. The technique of the distributed satellite constellation energy network architecture, wireless energy transmission technology, energy and information integrated transmission and joint scheduling technology will be discussed thoroughly. We also elaborate some design challenges and solutions of the key technologies for space energy Internet system. These studies lay the theoretical and engineering foundations for the future space energy Internet system.
