A distributed energy management method for a hybrid tire-type container crane

Abstract

The invention provides a distribution type energy management method for hybrid power rubber-tyred container cranes. The distribution type energy management method comprises the following steps of determining the sizes of three energy devices such as a diesel generator, a lithium battery and a super-capacitor, determining that a hybrid power system is of a structure of an active series topology, modeling the energy devices into independent intelligent bodies, performing preference analysis on the energy devices as game players, determining utility functions for evaluating the energy device benefits, performing the noncooperative current game on all the intelligent bodies, separately making the current decisions of maximal utility functions, adjusting the utility function and the current decisions of the energy devices according to the meeting requirements of a crane power demand and the benefit conditions of the energy devices to realize nash equilibrium, and converting the current decisions during equilibrium as control signals to control the devices to operate. The economic benefits and the environment benefits of a single energy device are effectively exerted in the hybrid powersystem, the fuel oil consumption of a traditional diesel power rubber-tyred container crane is reduced, and the initial investment can be reduced.

Description

technical field [0001] The invention relates to the field of energy optimization management of hybrid power equipment, in particular to a distributed energy management method of a hybrid tire type container crane. Background technique [0002] In recent years, my country's port container business has developed rapidly, and the port container throughput has been ranked first in the world for many years. Rubber-tyred container cranes are the main loading and unloading equipment in the world's major container port yards. The traditional RTG uses on-board diesel generators as the main power source, which has low energy conversion efficiency and high energy consumption. It will inevitably produce a large amount of mixed waste gases such as nitrides, sulfides, and carbides during use, which has become the most important emission source for container ports. . The disadvantages of high energy consumption and low efficiency of traditional cranes are becoming more and more prominent...
