Abstract

To effectively quantify the impact of distributed photovoltaic (PV) access on the distribution network, this paper proposes a comprehensive evaluation method of distributed PV grid connection combining subjective and objective combination of assignment and technique for order preference by similarity to an ideal solution (TOPSIS)—rank sum ratio (RSR) (TOPSIS-RSR) method. Based on the traditional distribution network evaluation system, a comprehensive evaluation system has been constructed. It fully considers the new development requirements of distributed PV access on the environmental friendliness and absorptive capacity of the distribution grid and comprehensively reflects the impact of distributed PV grid connection. The analytic hierarchy process (AHP) was used to determine the subjective weights of the primary indicators, and the Spearman consistency test was combined to determine the weights of the secondary indicators based on three objective assignment methods. The subjective and objective combination weights of each assessment indicator were calculated through the principle of minimum entropy. Calculate the distance between the indicators to be evaluated and the positive and negative ideal solutions, the relative closeness ranking, and qualitative binning by TOPSIS-RSR method to obtain the comprehensive evaluation results of different scenarios. By setting up different PV grid-connected scenarios and utilizing the IEEE33 node simulation algorithm, the correctness and effectiveness of the proposed subject-object combination assignment and integrated assessment method are verified.
