SCKF-LSTM Trajectory Tracking for Electricity–Gas Systems

What is it about?

This work introduces a novel method for monitoring the real-time behavior of combined electricity and gas networks. It integrates a robust filtering technique—the square-root cubature Kalman filter (SCKF)—with a long short-term memory (LSTM) network that forecasts gas loads. For the electricity system, it employs Holt’s exponential smoothing to handle rapid voltage changes, while for the gas system, it models pipeline dynamics using differential equations. Tested on a coupled power and gas network, this method significantly enhances the accuracy of tracking system states compared to traditional approaches.

Why is it important?

Efficient operation of integrated energy systems is critical for reliable and sustainable energy supply. However, tracking the dynamic behavior of such complex, nonlinear networks poses significant challenges. Our approach offers a timely solution by combining advanced filtering with deep learning to accurately predict system trajectories. This improvement in monitoring can lead to better energy distribution, heightened system stability, and a more resilient infrastructure—key factors for modernizing energy networks and supporting the shift toward sustainable energy sources.
