Abstract
AC/DC hybrid distribution mode is an important development direction of future distribution network.In order to overcome the limitation of power information transmission caused by different interest subjects of each subsystem,a dis-tributed optimization operation method of AC/DC hybrid distri-bution network based on improved analytical target cascading method was proposed.Firstly,in allusion to DC,VSC and AC region of AC/DC hybrid distribution network,the optimization models including regional operation optimization and inter-re-gional interactive power operation optimization were estab-lished respectively.Secondly,using the idea of distributed op-timization,the interaction power was used as a shared variable,the model objective function was decoupled,and a balance coefficient was introduced in the traditional analytical target cascading method to solve the problem of poor algorithm per-formance due to improper selection of the initial value of the penalty multiplier and unbalanced weights of subsystem func-tion terms and penalty terms,then the distributed model was solved iteratively under the consistency constraint.Finally,the effectiveness of the improved algorithm and the universality of the distributed model are verified by example simulation.关键词
