Research on Comprehensive Index Evaluation System of Hybrid Ac/Dc Distribution Networks

With the progress of power electronics technology, AC / DC hybrid distribution network has become an effective way to solve future distribution problems. This paper proposes a comprehensive index evaluation system for AC / DC hybrid distribution network based on relevant standards and references in view of the lack of a quantitative evaluation method. Firstly, the typical application scenarios of the AC / DC hybrid distribution network in the future are analyzed, and the corresponding development mode is established. Secondly, considering the constraints of various key technical indicators, a quantitative analysis method of various technical and economic indicators is proposed. A combination evaluation model of GRA + TOPSIS + RID for different application scenarios is constructed to optimize technical and economic indicators comprehensively. Finally, taking the actual data of a regional distribution network as an example, the correctness of the index and the feasibility of the evaluation model are verified. Moreover, the construction priorities in different scenarios are proposed, which can reference the development and construction of AC / DC distribution network in the future.
