Abstract:In the future, the airport power supply system will incorporate a variety of distributed power sources and gradually develop towards the airport microgrid. In order to improve the operating economy of the airport microgrid, the airport microgrid needs to apply a dispatching strategy. Aiming at the shortcomings of the traditional dispatching strategy in terms of speed and accuracy, taking the typical airport microgrid as the research object, an optimized dispatching model of the airport microgrid is established, and an improved sparrow search algorithm is proposed, which is compared with the basic sparrow search algorithm. Adding a non-linear change weight factor to prevent the algorithm from entering local convergence. This improved algorithm is used to solve the optimal dispatching of airport microgrid. The comparative analysis results show that the proposed improved sparrow search algorithm has the advantages of fast convergence speed and high optimization accuracy, which can effectively reduce the operating cost of airport microgrid.
