Problems solved by technology
[0003] However, if the shore power capacity allocation is too small, it will affect the emission reduction effect, and if the allocation is too large, it will cause waste of resources. How to reasonably determine the port shore power capacity has become a key issue in the promotion of shore power technology.
The existing methods for determining the shore power capacity of ports are mostly based on collecting historical port operation data, relying on expert experience or referring to adjacent projects, and fail to fully consider the connection of subsystems in the complex production operation system of the port and the randomness of ship arrivals and weather conditions. factors

Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings.
[0040] Taking the calculation of shore power capacity of a container port (a port area in the north) as an example, the calculation method is divided into three steps, as follows: figure 1 shown.
[0041] Step 1: Collect port-related data
[0042] The collected data includes port waterway data, port berth data, port loading and unloading equipment data, extreme weather data and ship-related data;
[0043] The port waterway data includes the length of the waterway and navigation rules. In this example, the channel outside the port is 20nm long, and the length and location of the channel in the port are as follows: figure 2 As shown, the navigation rules are: the safe time interval for ships to sail is 1 nautical mile, that is, the distance between the front and rear ships is not less than 1 nautical mile;
[0044] The port berth data includes the number of berths, ...

The invention discloses a method for determining the reasonable capacity of a harbor shore power system based on simulation optimization. The method comprises the following three steps: step 1, collecting port related data; step 2, establishing a port production operation system simulation model according to the data collected in the step 1, and outputting shore power occupation requirements of the ship at each moment; the simulation model is established by four subsystems, and the four subsystems comprise a ship berthing operation subsystem, a ship loading and unloading operation subsystem, arear land area operation subsystem and a ship unberthing operation subsystem; step 3, constructing a reasonable capacity determination optimization model of the harbor shore power system, and solvingand determining the reasonable shore power capacity of the harbor shore power system according to the output parameters in the step 3. Compared with the prior art, the method has the beneficial effects that the reasonable capacity of the shore power system when the ship randomly arrives at the port below the port can be quantitatively analyzed from the existing data, so that decision support is provided for popularization of the shore power technology and construction of a green port.
Description
technical field [0001] The invention belongs to the equipment configuration field of port engineering, is applicable to shore power systems of seaports and river ports, and specifically relates to a method for determining a reasonable capacity of a port shore power system based on simulation optimization. Background technique [0002] Energy saving and environmental protection have become the theme of the times. As an important hub of the international transportation network, the port is a large energy consumer, which produces a large amount of greenhouse gas emissions and air pollutants during production operations. Among them, the emissions generated by berthing ships using diesel power generation are the main source of port emissions. The use of shore power technology for berthing ships instead of traditional diesel power generation can significantly reduce the emission of greenhouse gases and air pollutants in ports. [0003] However, if the shore power capacity allocat...
