*5.3. Communication Weight Variation*

In this case, the effect of the communication weight on the speed of the system convergence is investigated. It can be seen from Equations (13), (14), and (18) that the communication weight *aij* affects the correction term δ1*i* and δ2*i*, which will affect the voltage reference. To simplify the controller design, in Figures 9 and 12, the communication weights *aij* are set to one for normal impact levels and five for high impact levels, respectively.

**Figure 12.** Distributed cooperative control when communication weights *aij* = 5: (**a**) DC-bus voltage; (**b**) battery SOC.

It can be seen in Figure 12a that the average CL DC-bus voltages reach the rated value for about 0.07 s regardless of the value of communication weight *aij*. Therefore, the communication weight has a weak impact on the convergence speed of the CL DC-bus voltage. However, in Figure 12b, the SOCs reach the consensus state faster with a larger *aij*. It can be concluded that a larger communication weight contributes to a faster convergence speed of SOC.
