4.5.2. Scenario 2

When the power limitation occurs, operations on machine M1 are completed. On the remaining machines, individual operations are started or the machines are set to the "Idle" state. In the production cell, two machines (M2 and M4) should constantly be in the "Processing" state (i.e., the machine setting parameters should enable the start or execution of the production process at any time). Due to the characteristics of the process, meeting this condition for machine M4 was not possible. However, for machine M2, it was possible in two variants, a reduction in power consumption by 5 or 10 kWh, while in other cases, it was again impossible. Table 8 presents the factors of the production process for different power limitations.

**Table 8.** Production process factors for scenario 2.


Increasing the amount of power limitations influenced the increase in the time execution of the production process by 29.4 min (with the 5 kW available power reduction) up to 113.4 min (with the 20 kW available power reduction). Increased process realization was associated with increased electricity consumption in the production cell—from 7.26 (variant 1) to 28.29 (variant 4) with respect to the base state (Table 6). Again, with the increase in the limitation of power consumption, the efficiency of individual machines used in the realization of the production process decreased. The maximum utilization of machine M3 decreased from the value of 89.66% (with the 5 kW available power reduction) to 76.56% (with the 5 kW available power reduction).
