Description

Port shore power intelligent dispatching method, device, equipment and medium Technical Field The present disclosure relates generally to the technical field of shore power dispatching, and in particular, to a method, an apparatus, a device, and a medium for intelligent port shore power dispatching. Background Shore power (shore power) is a term of navigation science technology published in 1996, and refers to a power supply mode of power generation by substituting fuel oil by accessing a land power network during the period of approaching a port of a ship, and comprises a high-voltage/low-voltage shore power system. Under the drive of global port green transformation and 'double carbon' targets, the shore power technology takes the advantages of replacing oil with electricity and reducing pollution emission of ships by port, and becomes a core technology path of port energy conservation and emission reduction. The land-based power grid is transmitted to the ship to replace a diesel generator for power supply, so that not only can the emission of pollutants such as sulfur oxides, nitrogen oxides and the like be obviously reduced, but also the noise pollution of ports can be reduced, and the land-based power grid has important environmental protection and social benefits and is a key measure for realizing the sustainable development of ports. Ship departure is a critical node in the stability of shore power systems. Before departure, the ship needs to gradually reduce the shore power supply and switch to the power supply of the marine generator, and the process needs to be stably transited, so that the impact on ship equipment and a port power grid is avoided. Meanwhile, power variation of the departure ship affects load balance of the whole port. Therefore, how to smoothly schedule the ship departure power connection becomes a problem to be solved.
