[0006] F.D. Kanellos, "Multiagent-System-Based Operation Scheduling of Large Ports' Power Systems With Emissions Limitation," in IEEE Systems Journal, vol.13, no.2, pp.1831-1840, June 2019, doi:10.1109 / JSYST. 2018.2850970. This document proposes a method based on a multi-agent system for the optimal operation of large ports, focusing on the port's own economy and environmental friendliness, without considering the optimization of energy trading strategies between port ships

Embodiment 1

[0131] A method for integrated operation of a port-vessel energy-transportation system based on a layered game provided by the present invention includes:

[0132] Step S1: formulate a layered game structure for the integrated operation of port and ship energy transportation;

[0133] In this layered game model, the port plays the role of the upper-level leader, and prioritizes the energy transaction price between ports and ships, and the ship plays the role of the lower-level follower, passively accepting the energy transaction price information released by the upper-level leader, but the charging and discharging of the ship The strategy in turn affects the ultimate return of the top leaders.

[0134] The step S1 is specifically adopted: in order to maximize the self-efficacy of all game participants, the port should not only consider its own interests when setting the energy transaction price, but also need to consider the dynamic response behavior of the ship, that is, ther...

Embodiment 2

[0236] Embodiment 2 is a preferred example of Embodiment 1

[0237] Considering that 15 all-electric ships with different cargo loads arrive at the port and participate in the energy transaction between the port ships, the port energy storage capacity is 24MWh, and the charging and discharging efficiency are both 85%.

[0238] refer to Figure 1 to Figure 3 As shown in this example, based on the layered game model, the port-ship energy and transportation integration system realizes the optimal decision-making of energy transaction prices between ports and ships and the orderly guidance of ships to participate in energy transactions at ports, effectively improving the overall operation economy. sex.

Abstract

The invention provides a port and ship energy traffic system fusion operation method and system based on a hierarchical game. The method comprises the following steps: S1, formulating a hierarchical game architecture of port and ship energy traffic fusion operation; s2, establishing a port and ship hierarchical game optimization model based on the optimization objective function and the optimization constraint condition of the port and the optimization objective function and the optimization constraint condition of the ship; s3, the hierarchical game architecture is based on the port and ship hierarchical game optimization model, and the port and ship energy traffic system optimal fusion operation method is obtained through a kkt optimality condition solving method; according to the port and ship hierarchical game optimization model, a port is used as a guider of an upper layer to make a strategy and execute the strategy, a ship is used as a follower of a lower layer to make a corresponding response with the strategy made by the port as a constraint, and the port updates the self strategy according to the response made by the ship until game equilibrium is achieved.

Description

technical field [0001] The invention relates to the technical field of optimized operation of a port and ship energy and transportation fusion system, in particular to a method and system for the fusion operation of a port and ship energy and transportation system based on a layered game, and more particularly, to a port and ship energy system based on a layered game theory Transportation system integration operation method and system. Background technique [0002] As an important hub linking sea and land, ports undertake key tasks such as logistics and transportation. Ships are the most important service objects in the port energy system, and their port-based service management and charge-discharge optimization management are effective means to realize the overall operation economy of ports and ships. [0003] In order to encourage energy interaction between ships and port energy sources, the present invention establishes a marine energy and service transaction mechanism t...
