Research on energy storage and hydrogen production system of offshore wind-solar hybrid power generation based on 3D finite element method

Abstract

At present, hydrogen, as a fuel, has the characteristics of high efficiency and no pollution, which can replace traditional fossil energy and be used in various fields to a certain extent. Using clean energy such as wind and light to electrolyze water to prepare hydrogen can realize zero pollution in the whole process from hydrogen preparation to use. Such energy conversion and use can reduce air pollution, improve air quality and solve the problem of abandoning wind and light. In this paper, a simulation model is established by using three-dimensional finite element method, and meteorological parameters are input into the model, so as to obtain the power generation, hydrogen production rate and the efficiency of converting solar energy, wind energy and electric energy into hydrogen energy under different capacity configurations of each part of the system. Using the model established in this paper, the parameters of wind and solar energy resources, environmental factors and load power in different regions are input. By changing the battery capacity, observing the battery operation and DC bus output, the battery equipment suitable for the whole system can be selected.
