Popis: In response to the challenges of large-scale integration of distributed photovoltaic (PV) sources into distribution networks, an integration capacity planning method for distributed photovoltaic sources based on generalized Benders decomposition (GBD) is proposed. The approach utilizes a data-driven sequential selection method to determine the optimal sequence of variables in the C-Vine Copula model. In combination with Latin hypercube sampling (LHS) and scenario evaluation indicators, typical load-resource correlation scenarios are constructed. Building upon these generated typical scenarios, the paper has established a photovoltaic source integration planning model based on the GBD. This model comprises a main problem for photovoltaic source planning and a sub-problem for distribution network operation, solved using linear programming and optimal power flow methods, respectively. Case studies are conducted on the grid framework of the IEEE 33-bus system. The results demonstrate that the proposed method for generating typical scenarios reduces resource and load errors by over 50% compared to traditional methods. Moreover, the computational complexity of the planning model is reduced by 11%, and the computation time is shortened by 9% compared to previous approaches.
