**5. Simulation Results**

Simulations are performed in the MATLAB/Simulink (2017a, MathWorks, Natick, MA, USA) to validate the performance of the proposed distributed cooperative control for the multiple DCESs. Table 1 reports the parameters of the study case utilized for simulation. To simplify the controller design, the communication weights are set to one. To verify the proposed distributed cooperative control, the resistance combinations of the CL and the NCL for the four DCESs are different from each other. Moreover, the droop coefficients of the four DCESs are also different according to the different output power.



The performance of the primary control and distributed cooperative control is discussed in detail as follows including the steady state, converter failure, communication weight variation, and load variation.
