Abstract

The present invention proposes a method for calculating the energy flow in the interval of an electric-thermal-hydrogen integrated energy system considering the correlation. First, the steady-state energy flow of the integrated energy system is established by combining the power network model, the thermal network model, the hydrogen network model and the coupling equipment model. Second, the parallelogram model is used to process the correlation between interval variables to obtain a more accurate energy flow interval boundary. To solve the complex and time-consuming problem of the optimization model of the energy flow equation, the linear optimization method and the deterministic performance flow method are used alternately to iteratively calculate the interval energy flow results. The invention can ensure the accuracy of the calculation result while improving the calculation efficiency of the interval energy flow.

Description

technical field [0001] The invention belongs to the technical field of integrated energy systems, and in particular relates to a method for calculating the energy flow in the interval of an electric-heat-hydrogen integrated energy system considering the correlation. Background technique [0002] The integrated energy system can realize flexible conversion between various energy sources, which is beneficial to improve the utilization efficiency of renewable energy. Energy flow calculation is an important basis for the operation analysis of the integrated energy system. However, there are uncertainties in the renewable energy, electric load, heat load, and hydrogen load in the integrated energy system, which bring uncertainty to the operating state of the system. , it is necessary to carry out the research on the uncertain energy flow of the integrated energy system. [0003] Uncertain energy flow includes probability energy flow, fuzzy energy flow and interval energy flow. ...
