Abstract A reasonable assessment of the bearing capacity of distributed power-generation sources in power systems is a key guarantee for the construction of new power systems with new energy sources as the core. In view of the fact that the current distributed new energy-bearing capacity assessment method has not yet established a systematic assessment index system and has not taken into account multisource complementarity, a new distributed energy-bearing capacity assessment method for power systems that takes into account the characteristics of multisource complementarity was proposed. First, a distributed new energy-bearing capacity assessment framework was constructed and the influencing factors of distributed energy-bearing capacity were analysed. Second, a multidimensional distributed power bearing-capacity assessment index system and calculation method considering thermal stability, short-circuit current, voltage deviation, and harmonics was proposed and the assessment process of distributed energy-bearing capacity was proposed. Finally, the validity and applicability of the proposed method were verified through actual case simulation.
