Review on Optimal Scheduling of Integrated Energy Systems

Integrated energy systems can improve the energy utilization efficiency and promote the consumption of renewable energy. This paper focuses on the optimal scheduling of integrated energy systems. The developing trend of the optimal dispatch of the integrated energy systems are firstly analyzed in terms of the papers' contents, published years and journals. Then the current status of the researches on the optimal scheduling of the integrated energy systems is summarized from three aspects: models, methods and strategies. On the basis of the basic models, the optimal scheduling models are illustrated in the different research priorities considering energy flow variability, considering system flexibility and considering system stochasticity respectively. The solution methods are discussed respectively from the classification of the analytical methods and the artificial intelligence methods. The simulation platforms for the integrated energy systems are compared in their features, functions, and applicable scenarios. Finally, the current problems and solution ideas are analyzed, and the future research direction is anticipated. The results of this paper will provide a reference for the study of the integrated energy systems. © 2021, Power System Technology Press. All right reserved.
