摘要：

The heterogeneity of grid operation is a basic state attribute of power system, which reflects the rationality of grid structure and the impact on the safety and reliability of grid operation. The influencing factors of grid operational heterogeneity are analyzed and a multi-objective optimization model is built for the hierarchical and partitioned expansion planning of power transmission network, which takes the CV (Coefficient of Variance) of transmission line load rate as the evaluation index of region-operational heterogeneity and considers the expansion cost and transmission line loss. Aiming at the dimensional disunity of multiple objectives, a genetic merit factor is defined and the genetic algorithm is improved to obtain the compromise solution of the proposed model. The case analysis for IEEE Garver 6-bus system and a regional transmission network planning verifies the effectiveness and feasibility of the proposed method.
