Priority Load Scheduling Under Utility Demand Thresholds

The system segments electrical loads into different priority groups (critical, important, desirable) and applies different control strategies to each segment. Critical loads are always energized, important loads are energized when beneficial, and desirable loads are energized only when beneficial and capacity is available. This segmentation resolves the contradiction by allowing selective energization that maintains customer satisfaction for essential loads while avoiding monetary charges through intelligent management of non-essential loads.

The system dynamically adjusts the energization state of electrical loads based on real-time conditions including available capacity, demand threshold proximity, and load priority. The load management computer continuously monitors the total load request and dynamically switches loads on or off to maintain operation below the demand threshold while maximizing utility. This dynamic control resolves the contradiction by adapting load energization to changing system conditions.

The system applies different quality levels of service to different loads based on their priority classification. Critical loads receive guaranteed service with no de-energization, important loads receive preferential treatment being energized first when capacity is constrained, and desirable loads are the first to be de-energized when necessary. This local differentiation of service quality resolves the contradiction by ensuring customer convenience is maintained for essential loads while accepting reduced convenience for non-essential loads to avoid monetary charges.

The system performs preliminary classification of loads into priority groups before demand management is needed. This advance organization allows the system to quickly make optimal decisions when capacity constraints arise, energizing or de-energizing appropriate loads without disrupting customer convenience for essential services. The preliminary segmentation resolves the contradiction by pre-establishing a hierarchy that protects customer convenience where it matters most.

The system divides the control function into distinct modules: a monitoring component that tracks total load request and demand threshold, a classification component that categorizes loads by priority, and a control component that executes energization/de-energization decisions. This segmentation of control functions achieves precise load management while containing system complexity through modular design, with each module having a specific, simplified role.

The load management computer serves as an intermediary between the electrical loads and the demand threshold constraint. It receives status information from loads, processes this information against predefined priority rules and threshold criteria, and generates control signals to appropriate loads. This intermediary approach achieves precise load management by centralizing the decision-making logic, avoiding the need for complex distributed control while maintaining measurement precision through continuous monitoring.
