Grey System Theory in Energy Consumption Forecasting
Research Guide

What is Grey System Theory in Energy Consumption Forecasting?

Grey System Theory in Energy Consumption Forecasting applies GM(1,1), nonlinear grey models, and multivariable grey models to predict energy demand patterns with limited data.

Researchers optimize these models using techniques like moth-flame optimization (MFO), fractional-order derivatives, and neural networks for time series forecasting. Key papers include Zhao et al. (2016) with 68 citations on MFO-optimized GM(1,1) for electricity consumption and Wu et al. (2015) with 64 citations on novel grey models for natural gas. Over 10 provided papers since 2012 demonstrate applications in electricity, natural gas, and CO2 emissions.

Key Challenges

Why It Matters

Grey models enable accurate energy demand predictions in data-scarce environments, supporting grid operators and policymakers in resource allocation (Zhao et al., 2016; Wu et al., 2015). They aid sustainable planning by forecasting electricity consumption in regions like Inner Mongolia and natural gas in China, reducing uncertainty in energy policy (Li and Zhang, 2018). Applications extend to CO2 emissions intensity forecasting, helping meet national targets like China's 60-65% reduction by 2030 (Li et al., 2020).

Key Research Challenges

Limited Historical Data

Grey models excel with small datasets but struggle with non-stationary energy time series requiring rolling mechanisms (Zhao et al., 2016). Traditional GM(1,1) shows reduced accuracy for long-term forecasts without optimization (Li and Zhang, 2018).

Model Optimization Complexity

Integrating MFO, genetic algorithms, or fractional derivatives increases computational demands while improving fit (Fan et al., 2018; Hu et al., 2021). Balancing parameter tuning with prediction precision remains difficult (Wu et al., 2015).

Multivariable Integration

Incorporating economic growth, emissions, and consumption variables demands advanced multivariable grey models with neural networks (Chiu et al., 2020). Handling interval grey numbers for uncertain inputs adds forecasting uncertainty (Xie and Liu, 2015).
