Under the penetration of high proportion of renewable energy, the problem of power congestion in multi-microgrid contact line is becoming more and more prominent. A comprehensive evaluation method based on the scheduling and operation results of the multi-microgrid system was proposed in this paper, aiming at addressing this problem, which can enable the reasonable allocation of congestion power and profit. Firstly, the structure and scheduling strategy of the hybrid multi-microgrid system were described in this paper, and the evaluation indexes of economy, environmental protection, and reliability of each sub-microgrid scheduling were formulated.; Secondly, to solve the problem of contact line power obstruction, the energy management system of multi-microgrid utilized the hierarchical analysis-entropy weight-game theory combination weight method to weight the indicators of each sub-microgrid, and then combines with the Technique for Order Preference by Similarity to Ideal Solution(TOPSIS) method to carry out the comprehensive evaluation of each sub-microgrid; and finally, it utilized the results of the comprehensive evaluation for the distribution of contact line congestion power and profit. The results show that the evaluation indexes used in this paper are reasonable, and the proposed method can improve the profit of the Multi-microgrids by 5.18%, and at the same time reasonably distribute the congestion power and profit of the Multi-microgrid contact lines.
