Method and system for power generation and voyage optimization of mobile energy network influenced by wind resources

Abstract

The invention provides a method for power generation and voyage optimization of a mobile energy network influenced by wind resources, including: selecting four characteristics of wind speed, temperature, air pressure and cloud cover as the data input for prediction; Training set and test set; normalize the sample data. Based on the data-driven mobile energy network power generation and voyage joint optimization method, the present invention takes the influence of the offshore wind speed on the speed of the all-electric ship into account, and can more effectively adjust the actual ship speed and achieve better ship energy management; The operation cost objective function is optimized, and the operation cost of energy storage is taken into account, which is more in line with the actual operation scenario; through the piecewise linearization method, the optimization model is converted into a mixed integer linear programming model, which solves the problem that mixed integer nonlinear programming is difficult to solve. problem; not limited to all-electric ship power systems, but can also be used in mobile energy networks such as land electric vehicles.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence and ship power system operation, in particular, to a method and system for power generation and voyage optimization of a mobile energy network influenced by wind resources. Background technique [0002] In recent years, under the general trend of green and low-carbon development, as a typical mobile energy network, the pollution emissions and low energy efficiency of all-electric ships have become the focus of attention of various countries. How to effectively manage the energy of the mobile energy network and optimize the control of ships Operating costs and reducing the level of greenhouse gas emissions have become urgent problems to be solved. [0003] At present, the energy management of mobile energy networks represented by the all-electric ship power system is mostly based on on-board energy storage or new energy power generation technology, focusing on the optimization of th...
