"Minimum operating time before shut-down" refers to the minimum duration that a device or equipment must remain operational before it can be shut down. This constraint is imposed to avoid inefficiencies caused by frequent stops and restarts of the equipment.
"Minimum stand-by time before start-up" refers to the minimum duration that a device or equipment must remain in a standby state before it can be started. This constraint is necessary to ensure the stability and efficiency of the equipment. Allowing sufficient standby time before starting ensures that the equipment goes through initialization and stabilization processes, enabling it to operate in an optimal state.
"Minimum operation load" sets the minimum load or demand that a device or equipment should operate at. This constraint ensures that the equipment operates within a specified range of capacity utilization, avoiding low utilization or inefficient operation.
"Model Operation with different performance characteristics" acknowledges that each device or equipment can have different performance characteristics.
For example, there may be variations in heat transfer efficiency, electrical conversion efficiency, fuel consumption, and other parameters among different equipment. This constraint allows for considering the performance characteristics of each equipment when developing an optimal operation plan.
Hot Start refers to the scenario where the equipment is already at operating temperature and can be quickly started without the need for significant heating or preparation.
Warm Start involves equipment that has been partially shut down or placed in standby mode, requiring some heating or preparation before resuming full operation.
Cold Start refers to equipment that has been completely shut down and requires extensive heating or preparation to reach the desired operating temperature.
