Air-Conditioner Temperature Control for CPP Demand Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing demand response programs, such as Critical Peak Pricing (CPP), rely on manual adjustments that are cumbersome and uncertain, affecting power consumption suppression and user convenience, especially considering factors like room structure, objects, and occupant presence.
Innovation Solution
A customer-dedicated energy management apparatus that includes an air-conditioner partial-road characteristics identification unit, intra-room heat-capacity characteristics identification unit, air-conditioning power-consumption-amount suppression target value calculation unit, air-conditioning setting temperature calculation unit, and air-conditioner control unit to determine and implement optimal setting temperatures for power consumption suppression during CPP events, minimizing user discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If manual adjustment of air conditioner usage is implemented during CPP events, then power consumption suppression can be achieved, but the operation becomes troublesome and uncertain
Solution Approach 1:
The system automatically adjusts air conditioner usage during CPP events based on pre-stored control logic and real-time temperature data, eliminating the need for manual user intervention. The air conditioner control unit autonomously determines whether to operate the air conditioner based on current temperature, target temperature, and CPP event status, thereby resolving the contradiction between energy suppression and operational convenience.
2Loss of energy
If stronger suppression of power consumption is implemented, then the effect on electric-price reduction is ensured, but the convenience and comfort of the user is damaged
Solution Approach 1:
The system dynamically adjusts the control parameters (target temperature, operation timing) based on current environmental conditions (actual temperature, temperature change rate) and room characteristics (heat capacity). By changing these parameters adaptively rather than applying fixed strong suppression, the system achieves sufficient power consumption reduction while maintaining user comfort within acceptable temperature ranges.
Solution Approach 2:
The system pre-stores control logic and characteristics data before CPP events occur, and performs preliminary temperature adjustments when conditions permit. This allows the system to prepare for upcoming high-price periods by adjusting temperatures in advance, reducing the need for extreme suppression during actual CPP events, thereby maintaining comfort while achieving price reduction goals.
3Ease of operation
If automated control system is implemented, then troublesome manual operation is eliminated, but the system complexity increases
Solution Approach 1:
The air conditioner control unit serves multiple functions: normal operation control, CPP event response, temperature monitoring, and automated decision-making. By integrating these diverse functions into a single control unit that processes information from existing sensors and executes comprehensive control logic, the system achieves high automation without proportionally increasing overall system complexity.
