【Abstract】 The optimal operation of the energy hub in the integrated energy system contributes to the improvement of energy utilization efficiency and is one of the research hotspots in the integrated energy system.Based on the structure and operation mechanism of the energy hub,ageneral energy hub model was established.The optimal operation of the energy hub is studied by using particle swarm optimization algorithm with the lowest operation cost as the objective function.This method effectively considers the impact of energy price and load characteristics in different seasons on the operation of the energy hub,and makes a comparative analysis with the two operation modes of power and heat.The example simulation shows that the optimal operation of the energy hub not only has more economic benefits,but also is conducive to the safe and stable operation of the power grid.更多还原
