Abstract：Micro-energy network is an integrated energy system that integrates various types of distributed energy systems, storage systems and loads. However, the capacity of the micro-energy network is relatively small,and multiple micro-energy networks with similar distances can be interconnected for energy sharing. Firstly, a typical structure of micro-energy network interconnection system is proposed. Secondly, according to the distributed energy system and load types included in the system, the frequency modulation and load characteristics are analyzed. A criterion for frequency stability of interconnected systems is presented along with an analysis method for the modulation capability. Then an optimal scheduling model is established based on the intermittent energy consumption rate. At last, a case study is given to compare the frequency stability and the ability to absorb intermittent energy of the system before and after interconnection, which verifies the effectiveness and feasibility of the proposed theory.
