1Use of energy by moving object
If the building transitions to all-electric systems, then electrical power consumption increases, but the existing electrical service panel capacity becomes insufficient
Solution Approach 1:
The system dynamically adjusts the operation of flexible loads based on real-time current level detection. The controller monitors the electrical current and automatically modulates flexible load operation to maintain current levels below the panel's maximum capacity, enabling the panel to handle variable all-electric demands without upgrading.
Solution Approach 2:
The system changes the operational parameters of flexible loads (such as power consumption levels, operating hours, or load intensity) based on detected current levels. When current approaches the panel's capacity limit, the controller adjusts flexible load parameters to reduce consumption, thereby maintaining reliable operation within the existing panel's capacity constraints.
2Power
If the electrical service panel is upgraded to handle increased power demands, then the panel capacity increases, but the cost of upgrade increases significantly
Solution Approach 1:
Instead of physically upgrading the panel infrastructure, the system creates a virtual capacity expansion through intelligent control. The load control device effectively 'copies' the function of a larger panel by dynamically managing load distribution and consumption, allowing the existing panel to deliver the performance of a higher-capacity panel without the associated upgrade costs.
Solution Approach 2:
The system achieves effective panel capacity expansion by changing the operational parameters of connected loads rather than changing the panel's physical capacity. The controller adjusts flexible load parameters to optimize power consumption patterns, effectively increasing the usable capacity of the existing panel without any physical upgrades.
3Power
If the utility infrastructure is upgraded to accommodate increased power demands, then the power delivery capacity increases, but the infrastructure upgrade cost increases
Solution Approach 1:
The system creates a virtual infrastructure capacity expansion through intelligent load management. Rather than physically upgrading transformers, power lines, and other utility infrastructure, the load control device effectively copies the function of enhanced infrastructure by optimizing power consumption and distribution at the building level, eliminating the need for expensive utility upgrades.
Solution Approach 2:
The system performs preliminary load management actions to prevent peak demand conditions that would require infrastructure upgrades. By proactively adjusting flexible loads before demand peaks occur, the system prevents the need for utility infrastructure expansion, as the building's power consumption is kept within the existing infrastructure's capacity.
4Productivity
If flexible loads are increased to meet higher power demands, then the electrical power consumption capacity increases, but the current level may exceed the panel's maximum continuous load rating
Solution Approach 1:
The system continuously monitors the electrical current level and uses this feedback to automatically adjust flexible load operation. The controller receives real-time feedback on current consumption and dynamically modifies flexible load parameters to maintain current levels below the panel's maximum continuous load rating, thereby increasing power consumption capacity while preventing harmful overload conditions.
Solution Approach 2:
The system dynamically balances power consumption capacity and safety by continuously adjusting flexible load operation based on real-time conditions. The controller modulates flexible loads to maximize power consumption within safe operating limits, automatically adapting to changing conditions to maintain both high productivity and protection against overload.

AI summary
In one embodiment of a method of controlling a level of consumption of electrical power distributed by an electrical panel using a load control device, electrical power supplied through the electrical panel is consumed using electrical devices. A current level of the electrical power is detected using a power meter. The detected level is compared to a load limit corresponding to a percentage of a maximum continuous electrical load rating for the electrical panel. When the detected current level is less than the load limit, increasing electrical power consumption by one or more flexible loads of the electrical devices to increase the current level using a controller of the load control device. When the detected current level is greater than or equal to the load limit, decreasing electrical power consumption by the one or more flexible loads to decrease the current level using the controller.
