Load Scheduling Control for Peak Demand and Capacity Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for electricity and the simultaneous activation of numerous loads in electricity-consuming fields often leads to excessive power consumption, causing overload trips and exceeding contracted electricity capacity, resulting in additional billing costs.
Innovation Solution
A power control system and method that categorizes loads into essential and non-essential groups, allowing non-essential loads to operate during off-peak periods, and optionally reducing their power consumption during peak periods, using a processing module to manage electricity consumption data and a control module to adjust load operation based on scheduled consumption status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large number of loads are activated simultaneously to meet increasing electricity demand, then the power consumption increases to satisfy user needs, but the switch device trips due to overload or the contracted electricity capacity is exceeded
Solution Approach 1:
The system performs preliminary classification of loads into essential and non-essential groups, and predicts peak period electricity consumption in advance. This allows the control module to pre-adjust non-essential loads before the peak period begins, preventing overload trips while ensuring essential loads remain operational during high-demand periods.
2Reliability
If non-essential loads are controlled to operate during off-peak periods to reduce peak consumption, then electricity capacity compliance is improved, but the flexibility of load operation is reduced
Solution Approach 1:
The system dynamically adjusts the operation timing of non-essential loads based on real-time electricity consumption data and peak period predictions. The control module can flexibly schedule non-essential loads during off-peak periods when consumption is low, while allowing them to operate during peak periods when necessary, thus adapting to changing conditions while maintaining electricity capacity compliance.
3Loss of energy
If essential loads are allowed to operate during both peak and off-peak periods while non-essential loads are restricted during peak periods, then electricity consumption control is improved, but the system complexity increases
Solution Approach 1:
The system segments loads into essential and non-essential categories, and further divides non-essential loads into first and second groups based on their operational flexibility. This segmentation allows the control module to apply different control strategies to different load groups: essential loads operate freely, first group non-essential loads can operate during peak periods with reduced power, and second group non-essential loads are restricted during peak periods. This hierarchical segmentation simplifies the control logic while achieving effective electricity consumption management.

AI summary
A power control system includes a processing module, a database, and a control module. A power control method thereof includes: obtain an electricity consumption of loads from the electricity consumption metering device through a processing module, and generate a scheduled electricity consumption status in an electricity consuming period of the electricity consuming field; the scheduled electricity consumption status includes a peak period and an off-peak period; create a load data in the database; the load data sorts the loads into a first electricity consuming group and a second electricity consuming group; the loads of the first electricity consuming group are defined as an essential load, and the loads of the second electricity consuming group are defined as a non-essential load; control the loads of the second electricity consuming group to run during the off-peak period through a control module based on the load data and the scheduled electricity consumption status.
