| Building high- penetration renewable energy systems is the only way to achieve carbon neutrality, but the output of renewable energy is fluctuating and seasonal. In order to realize the long-term planning of renewable energy, with the goal of minimizing the annualized cost, the links of production-storage-hydrogen use are included in the planning and decision-making of renewable energy, and a comprehensive system has been established.The hydrogen energy storage-based renewable energy system model for annual time series production simulation unifies the system cost problem and the operation simulation problem to the planning level. In order to verify the superiority of the renewable energy system based on hydrogen energy storage, the annualized cost of the renewable energy system based on battery energy storage is compared. In order to verify the applicability of areas with different wind and solar resources, the planning results of areas with different wind and wind resources characteristics are compared. Finally,the sensitivity analysis of the dispatchable energy price and the input power change of the electrolyzer equipment to the system parameters is introduced. The calculation example shows that the seasonal storage of electric energy in the hydrogen energy storage systems in the two regions has obvious advantages in terms of economy and curtailment rate, although it has disadvantages in comprehensive efficiency.
