Modeling of Ship Micro-Grid Based on Wind and Solar Power Generation Technology

Abstract

Under the influence of environmental issues and energy crises, wind and solar power generation technologies have developed rapidly. Compared with terrestrial micro-grid, this technology has relatively few applications on ships. Aiming at the problems of low energy utilization rate of ship micro-grid, imperfect control strategy, and single simulation situation, this paper uses the construction method of terrestrial micro-grid to build a detailed ship micro-grid model based on wind and solar power generation technology on the MATLAB/simulink simulation platform, and uses hill climbing search Method and disturbance observation method to control wind and photovoltaic power generation system. In the simulation process, several situations of wind speed, light intensity, and load sudden changes during the operation of the micro-grid were simulated. The simulation results show that the micro-grid model can track the maximum power point in real time, and the wind energy utilization rate is increased to 0.48, and the bus voltage and current are equal. The actual operation requirements are met, and the correctness and effectiveness of the simulation model and control strategy are verified, which is helpful to the in-depth study of the construction of the ship micro-grid model.
