Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If demand response policies are implemented by directly interacting with consumer electrical equipment, then electrical energy demand can be regulated to balance supply and demand, but the equipment complexity and operation difficulty increase significantly
Solution Approach 1:
The patent introduces a management module as an intermediary between the supply network and cyclic electrical devices. This module monitors network frequency and automatically adjusts device operation schedules without requiring direct user interaction or complex equipment modifications at the consumer end. The intermediary handles the complexity of demand balancing while presenting a simple interface to both users and devices.
Solution Approach 2:
The management module enables cyclic electrical devices to self-adjust their operation schedules based on network conditions. By monitoring frequency deviations and automatically modifying cycle phases, the system achieves demand balancing through self-service mechanisms rather than requiring complex external control equipment or technician intervention.
2Use of energy by moving object
If demand response policies require direct interaction with consumer electrical equipment, then energy consumption can be controlled, but technician intervention and installation complexity increase
Solution Approach 1:
The management module is designed to be integrated with or automatically connected to cyclic electrical devices, enabling energy consumption control without requiring technician intervention for installation or operation. The module autonomously monitors network frequency and adjusts device schedules, making the system easy to deploy and operate while effectively managing energy consumption.
Solution Approach 2:
The management module serves as an intermediary that simplifies the interaction between the supply network and consumer equipment. It handles all complex control functions centrally, allowing standard cyclic electrical devices to be controlled without modification, thereby improving ease of operation and installation while maintaining energy consumption control.
3Ease of operation
If cyclic electrical devices operate according to fixed nominal cycles, then device operation is simple, but demand balancing with the supply network becomes difficult
Solution Approach 1:
The patent introduces dynamic adjustment of cyclic device operation schedules based on real-time network frequency conditions. The management module modifies cycle phases and durations dynamically in response to supply-demand imbalances, allowing the system to maintain simple device operation while achieving reliable demand balancing through adaptive schedule changes.
Solution Approach 2:
The system implements feedback control by continuously monitoring network frequency and using this information to adjust cyclic device schedules. The management module detects frequency deviations and automatically modifies operation patterns, creating a closed-loop system that maintains demand balancing while preserving operational simplicity through automated responses.

AI summary
The invention relates to a method for managing a group of electrical devices (EQi) connected to an electrical power supply network (R), said group comprising at least one so-called cyclic electrical device initially employing a nominal cyclic operation comprising a plurality of nominal cycles, each having a first nominal phase during which the cyclic electrical device draws electrical power from the network in order to regulate a characteristic quantity, and a second nominal freewheeling phase. The method comprises: planning the operation for a cyclic electrical device, defining, for said cyclic electrical device, at least one cycle phase that is altered relative to the corresponding nominal phase, said planning being based on at least (i) the nature of the current phase from among the first and second nominal phases, (ii) a quantity adapted to be representative of an imbalance between a request for electrical power made to the supply network and the electrical power made available by the supply network, (iii) and a quantity representative of an estimate of the value of the characteristic quantity of the cyclic electrical device relative to a set value of the current phase; and implementing said planning from a start time.
