Research Status and Prospect of Optimal Operation of Integrated Energy System
In order to fully consume clean energy and improve energy efficiency
the concept of integrated energy system was put foward. Compared with the traditional single-stage energy utilization
integrated energy system makes multi-level use of various forms of energy such as power
heat and cold and natural gas
and achieves the improvement of integrated energy utilization efficiency through multi-energy complementarity. However
due to the close coupling between the systems and the complex changes of energy flow
the integrated energy system is quite different from the traditional power grid in terms of optimal operation. The research status of optimal operation of integrated energy system was comprehensively sorted out. Firstly
the composition of integrated energy system was introduced. The research status of power
heat and natural gas network power flow models was summarized and analyzed. Secondly
the optimal operation methods were classified and summarized
and the advantages
disadvantages and difficulties of existing methods were analyzed. Finally
the future research direction of the integrated energy system was pointed out.
