Investment Model and its Multi-year Rolling Deduction Based on a Data-driven Method for Distribution Network

With the access of large-scale clean energy, in the face of a lot of reconstruction strategies, the problems of complexity and poor convergence exist in the traditional investment planning optimization model which includes optimal power flow (OPF) and network safety constraint (NSC). Thus, an optimal investment decision model of distribution network (DN) is proposed based on the correlation constraint between reconstruction strategies and reliability which is obtained by a data-driven method, as well as the iteration calculation of reliability index. Based on the correlation, the multi-year investment model is established respectively aiming at maximizing the index and minimizing the total investment cost to obtain the optimal investment plans. Finally, an example is given to verify the rapidity, feasibility and effectiveness of the investment model.
