The photovoltaic power is exposed to several weather conditions issues like partial shading, rapid change, and non-uniformities. Accordingly, this paper contributes to managing and controlling a decentralized cluster of DC Microgrids subjected to influences of PV outputs on system performances. To maintains the bus voltage stability, overcomes power mismatches, and mitigating stress on energy storage devices under fixed and varying temperature scenarios, this paper proposes cooperating energy management with dual-loop structure-based high dynamic control, where reference currents of bus voltage regulator compensate energy management setpoints to overcome their decisions' uncertainty. The findings revealed less perturbed bus voltage under balanced temperatures with irradiances with a deviation of 1.25, 1.33](%), contrasted to fixed temperature with increasing irradiances scenario 1.6, 1.96](%). Strengthened by optimized average root-mean-square-errors (RMSE) of inductor currents and bus voltage with 0.25(A), 0.13 (V) versus 0.34(A), 0.27 (V), homogenous weather conditions preserve smooth power-flowing under robust control. In the power-flowing stability context, the system was more smoothed and efficient 92.7% preserving balanced temperatures with irradiances, so it was more disturbing and low efficient 92.08% despite maintaining lower temperature. Consequently, non-uniform increases of the ambient temperatures with radiation intensity negatively disturb the system's functioning despite tracking higher PV power.
