Application of wind photovoltaic microgrid with hydrogen energy storage system in industrial aquaculture enterprises

Abstract The high electricity consumption problem of industrial aquaculture has been the bottleneck limiting the large-scale promotion of this new aquaculture technology. At the same time, aquaculture enterprises also need a certain amount of heat energy and oxygen. Taking into account the features of the hydrogen energy storage system that generates heat and oxygen during the process of storing and releasing electrical energy, the wind photovoltaic microgrid with hydrogen energy storage system is proposed and applied to industrial aquaculture to realize the integrated supply of thermal energy, electrical energy, and oxygen to reduce the energy cost of enterprises. In this paper, the microgrid cogeneration energy storage model with wind turbines, solar arrays, thermal storage system, oxygen storage system, and hydrogen storage system is built using the Matlab/Simulink program. In the meantime, the model was put in a Penaeus Vannamei industrial aquaculture enterprise in Guangdong to simulate the energy supply of the microgrid with hydrogen energy storage system, and the system's costs and benefits were then compared to those of the microgrid battery energy storage system. The simulation findings confirmed that the system can satisfy the business's energy needs at a lower cost and with more financial success than the current battery energy storage microgrid system. The research results are expected to provide new ideas and methods for reducing energy costs in industrial aquaculture.
