Review on Modeling and Energy Flow Calculation Methods for Integrated Energy Systems
Around the energy flow calculation problem of integrated energy system, various energy flow calculation methods are reviewed from two aspects: network model and solution, uncertain performance flow analysis method. Firstly, in the aspect of network characteristics modeling of integrated energy system, partial differential equation model, dynamic model and steady state model and their solutions are discussed. Secondly, two types of energy flow analysis methods for dealing with external uncertainty, namely probability and interval, were summarized, and energy flow analysis methods with mixed uncertainty in probability interval. Finally, we analyze the difficulties and hotspots of energy flow calculation from the perspective of engineering applications, and then provide prospects for its development direction.
