LNG ship dynamic behavior-based port energy system coordination optimization method and system

The invention provides a port energy system coordinated optimization method and system based on LNG ship dynamic behaviors. The method comprises the following steps: constructing a navigation planning model of the LNG ship dynamic behaviors; constructing a port energy system coordinated scheduling model based on LNG ship dynamic behaviors; on the basis of the optimal solution of the navigation planning model of the LNG fleet, solving the port energy system coordinated scheduling model based on the dynamic behaviors of the LNG ships to obtain an optimal scheduling decision; the navigation planning model of the LNG ship dynamic behavior aims at minimizing the transportation and distribution cost and the air shortage rate, meanwhile, capacity limitation and time window limitation of different types of LNG transport ships are considered, a small LNG transport ship cluster is optimized and dispatched, and it is guaranteed that all receiving stations receive liquefied natural gas on time; according to the port ener
