Optimal configuration and solution of wind-photovoltaic hydrogen storage coupling off-grid system based on construction cost

The present study investigates the potential for enhancing the allocative efficiency of a coupled off-grid system comprising wind power, photovoltaic technology, and hydrogen storage. A primary objective of this research is to reduce system construction costs. The exploration of configuration optimisation, capacity planning, and system reliability, two critical considerations, is a central tenet of this study. The construction of a capacity optimisation configuration model is predicated on the wind energy and light energy characteristics of the project site, with consideration given to load demand and cost constraints. The model focuses on the wind-photovoltaic hydrogen storage coupled off-grid system and performs a comprehensive analysis of the capacity allocation of wind power generation, photovoltaic power generation and hydrogen energy storage. The model's primary objective is to ensure that the load demand is met, improve energy efficiency, and effectively control costs. To this end, it evaluates the complementary effects of various energy sources, the time volatility, and the application effect of energy storage technology. The model's findings can provide a beneficial reference for similar projects. The optimal capacity configuration scheme of each subsystem is given.
