Abstract：In order to study the influence of the coupling strength distribution strategy for synchronization and stability of power grids,to explore a coupling mode to improve the synchronizability and stability of power grids, this paper proposes three coupling strength distribution strategies of power transmission lines, which are named EQ, TP and LB. Respertively, the EQ strategy means that all the line coupling strengths are equal. The TP strategy means that the coupling strength of a line is proportional to its power distribution which value is the case that synchronization is achieved with the equal coupling. The LB strategy means that a line coupling strength is proportion to its link betweenness. Simulation experiment is carried out on IEEE14, IEEE30, IEEE39, IEEE57 standard test net, as well as BA scale-free network and NW small-world network.The advantages and disadvantages of these three strategies are compared through synchronizability and stability of power grids. Study shows that the TP strategy is the best one, the LB strategy is the worst one among the three, the performance of the EQ strategy is in the middle.
