Abstract Aiming at the challenges brought by flexible regulation resource scarcity and efficient accommodation with high penetration renewable energy integration under ‘double carbon goal’, an accommodation strategy for renewable energy in distribution network considering coordinated dispatching of multi-flexible resources is proposed. The method is established to depict the flexible interaction between multi-flexible resources. Considering both renewable energy accommodation and operating costs of distribution network. The accommodation optimization model for renewable energy is established considering coordinated dispatching of multi-flexible resources. In order to obtain the feasible region of non-dominant solutions of the accommodation optimization model, a multi-objective optimization solution method is established based on bi-layer embedded structure, and the composite linearization strategy is proposed to recast the complex multi-objective, non-linear and non-convex accommodation optimization model to a multi-objective mixed integer linear optimization model so that the accommodation optimization model can be efficiently solved. Finally, the effectiveness and applicability of the proposed accommodation strategy are verified by IEEE 33 bus system and a practical 110 kV distribution network in China.
