Abstract

In order to solve the problems of uncertainty and seasonal imbalance of renewable energy output, an optimal allocation method of electric, heat, gas and hydrogen integrated energy system considering stepped carbon trading and seasonal hydrogen storage was proposed. Firstly, in order to reduce the complexity of long-term planning and calculation and maintain the long-term power fluctuation characteristics, in this paper, the K-means++ method based on improved silhouette coefficient clustering method is used to perform cluster analysis of wind and solar load data. Secondly, the seasonal hydrogen storage unit is modeled, and the stepped carbon trading mechanism is introduced into the optimal allocation model, and the optimal allocation model of the park integrated energy system with seasonal hydrogen storage is established with the minimum economic cost and carbon transaction cost as the objective function. Based on the comparison of different scenarios, the impact of different carbon trading mechanisms on the integrated energy system of the park is analyzed, and finally the effectiveness of the proposed model in improving the consumption, economy and carbon emissions of renewable energy is verified.
