Abstract：Decentralized multiple energy systems（DMES）are vital for energy transition and local efficient

utilization. The standards for DMES cover various fields，including distributed energy，microgrids，energy storage

technologies，and communication control，making the standardization work more systematic and complex.

Currently，there are gaps and blank areas in DMES-related international standards，and differing standards across

countries pose challenges for communication and integration. To regulate future DMES standardization efforts and

enhance China's influence in the international multi-energy complementary systems field，it is essential to extract

relevant standardization recommendations. An analysis of the applicability and gaps of existing standards related to

DMES was conducted，as established by standardization organizations such as IEC，ISO，and IEEE. Based on this

survey，the standardization needs and offers an outlook on future efforts in DMES standardization was summarized.
