Multi-objective Optimization Energy-saving Control Method for Integrated Energy System Based on Time Series

The use of a single objective function to optimize energy-saving control for integrated energy systems results in high energy consumption and poor energy-saving effect. Therefore, a multi-objective optimization energy-saving control method for integrated energy systems based on time series is designed. The time series analysis of the integrated energy system data is carried out to determine the system operation law and energy demand characteristics. A multi-objective optimization energy-saving control model is constructed based on the results of time series analysis. The experimental results show that after the application of the multi-objective optimization energy-saving control method for the integrated energy system, the total carbon emissions are significantly reduced and the fluctuation is small. The average output error rate of the unit is 4.5%~5.2%. The equipment operation strategy can be dynamically adjusted according to the real-time situation of the system, and it has obvious advantages in energy saving, emission reduction and improving energy utilization efficiency.
