Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing demand response technology lacks effective guidance and adjustment for carbon emissions due to the inability to accurately determine the actual carbon emission intensity on the demand side, resulting in low carbon emission regulation capability and failure to meet low-carbon emission demands.
Innovation Solution
A method and apparatus for calculating carbon emission response based on carbon emission flows, which involves calculating the total carbon flow rate of a power system, determining if it exceeds a threshold, and initiating a carbon emission response to reduce emissions, using a carbon emission flow model and network structure analysis.

Engineering Contradiction Analysis
1Reliability
If demand response technology adjusts power consumption based on power and energy balance, then power system security is improved, but carbon emission regulation capability deteriorates due to inability to obtain actual carbon emission intensity
Solution Approach 1:
The patent introduces carbon emission flow as an intermediary concept to bridge the gap between power flow and carbon emission regulation. By defining carbon emission flow rate at each node and branch, the system can indirectly calculate and regulate carbon emissions without directly measuring them, thus improving carbon emission regulation capability while maintaining power system security
Solution Approach 2:
The patent replaces direct carbon emission measurement (which would require complex sensing and measurement systems) with a calculation-based approach using carbon emission flow models. This substitution allows the system to regulate carbon emissions through computational methods rather than physical measurement, enhancing adaptability without adding measurement complexity
2Adaptability or versatility
If carbon emission flow calculation method is implemented, then carbon emission regulation capability is improved, but system complexity increases due to additional calculation requirements
Solution Approach 1:
The patent makes the existing power flow calculation system multi-functional by enabling it to calculate both power flow and carbon emission flow using the same network structure and flow tracing methods. This universality allows carbon emission regulation without requiring separate dedicated calculation systems, thus improving capability while limiting complexity increase
Solution Approach 2:
The patent extends existing power flow parameters by adding carbon emission flow rate parameters to each node and branch. By changing the parameter set to include carbon-related variables, the system gains carbon emission regulation capability while building upon existing power system analysis frameworks, avoiding complete system redesign

AI summary
The present disclosure provides a method and apparatus for calculating carbon emission response based on carbon emission flows. The method includes: calculating a total carbon flow rate of a power system from a carbon flow rate of each of carbon meter users, the carbon flow rate being obtained based on a carbon emission flow of the carbon meter user; determining whether the total carbon flow rate is greater than a carbon emission response threshold; and calculating, in response to determining that the total carbon flow rate is greater than the carbon emission response threshold, a target carbon emission reduction of one or more of the carbon meter users during a carbon emission response period based on target carbon emission response demand, and initiating a carbon emission response based on the target carbon emission reduction.
