Under the background of the global energy crisis and environmental issues, the efficient utilization of renewable energy as a kind of distributed energy resources, is paid more and more attention. However, the intermittency and unpredictability of the renewable energies limit its development and penetration. To deal with such a big challenge, the multi-source hybrid distributed energy system has been proposed. In this paper, the concept and characteristics of the multi-source hybrid distributed energy system are discussed. In addition, three main forms of the proposed innovation energy system are presents and compared.
