In response to the large-scale energy consumption of oil-gas enterprises, the increasing demand for traditional energy structure adjustment, and the low efficiency of new energy utilization, this study conducts integrated research on the wind-solar-hydrogen-energy storage system. The system integrates wind power generation, hydrogen production, energy storage, and intelligent control to achieve coordinated operation of multiple energy sources. The analysis focuses on the multi-energy coupling architecture, key integration technologies, and engineering application paths. The system’s operational effectiveness is evaluated based on actual cases. The results show that the integrated system can achieve efficient utilization of new energy, maintain stable operation of the wind power generation and hydrogen production units, control the response time of energy storage within 100 ms, and increase the energy utilization efficiency by approximately 15%, improving the system’s operational stability. The wind-solar-hydrogen-energy storage system can promote the optimization of the energy structure of oil-gas enterprises, enhance the overall energy management level, and provide technical support for the green and low-carbon transformation.
