Decomposition of air conditioning electricity consumption based on effective duration

Area of Science:

• Energy Systems Engineering
• Building Energy Analysis
• Power Grid Management

Background:

• Growing air conditioning electricity consumption necessitates accurate usage breakdown for grid stability.
• Existing literature inadequately addresses the impact of apparent temperature on AC energy use.
• A lack of effective indices hinders the evaluation of AC electricity consumption decomposition accuracy.

Purpose of the Study:

• To develop a method for decomposing air conditioning electricity consumption based on effective duration.
• To integrate apparent temperature modeling into AC consumption decomposition.
• To propose novel evaluation metrics for assessing the efficacy of consumption breakdown.

Main Methods:

• Utilized effective duration as the basis for decomposing air conditioning electricity consumption.
• Employed an apparent temperature model as a constraint to identify effective air conditioning operating time.
• Constructed a constrained convex optimization problem to estimate air conditioning power usage.

Main Results:

• The proposed decomposition methodology demonstrates closer alignment with actual electricity consumption data.
• The novel evaluation index, including penalties for negative decomposed consumption, enhances assessment accuracy.
• Empirical results from Fujian Province validate the effectiveness of the new approach.

Conclusions:

• The developed method provides a more accurate decomposition of air conditioning electricity consumption.
• The proposed evaluation metrics effectively gauge the quality of AC electricity consumption data.
• This work contributes to improved electricity usage pattern assessment and power grid management strategies.
