Renewable energy sources such as hydrogen,photovoltaics,and wind energy are important ways to achieve the dual carbon goals and carbon emission control goals. Due to the significant fluctuations in renewable energy generation,the dual risks of load loss and power abandonment are highlighted,which puts higher demands on the flexibility of energy systems.This article proposes a low-carbon scheduling model based on flexibility quantification for a high proportion renewable energy integrated energy system.Firstly,analyze the operational characteristics of flexible resources in multi energy coupled equipment,construct a comprehensive energy system flexible resource model,and combine the utilization and emission of carbon dioxide in system equipment to achieve deep utilization of carbon dioxide within the system;Secondly,considering the source load fluctuation of the system,combined with the quantitative difference in flexibility between the integrated energy system and the power system,the quantitative analysis of energy,power,and slope flexibility of the park system is achieved;Finally,combining the differentiated regulation characteristics of system flexibility resources with the supply-demand differences of system flexibility at different time scales,multi time scale scheduling is carried out to mitigate the flexibility requirements brought about by the uncertainty changes of renewable energy and small time scales of load. This article takes a comprehensive energy industrial park in the south as the experimental background,and uses the method proposed in this article to analyze and schedule,verifying the power and electricity balance of flexible resources at different time scales,which is conducive to improving the flexibility and low-carbon characteristics of the comprehensive energy electricity-gas-heat system.
