在规划阶段，通过风光储氢耦合分析论证合理的项目建设规模是项目开发的难点和重点。本文通过分析风光储制氢系统的能量平衡，建立风光出力、储能和制氢耗电的能量平衡模型，并采用动态成本计算方法计算全生命周期的单位立方氢气成本，以单位立方氢气成本最低为优化目标，得出最优的风光和制氢容量配置，使风光储制氢项目的系统配置有依据。风电出力和光伏出力由于出力特性不同，形成互补之势，对提高氢能设备利用率、降低制氢成本有较大推动作用。

In the planning stage,the analysis of wind solar hydrogen storage coupling proves that a reasonable project construction scale is the difficulty and focus of project development.This article analyzes the energy balance of the wind solar hydrogen storage system,establishes an energy balance model for wind solar output energy storage and hydrogen production power consumption,and uses dynamic cost calculation method to calculate the unit cubic hydrogen cost throughout the life cycle.The optimization goal is to minimize the unit cubic hydrogen cost,and obtain the optimal wind solar and hydrogen production capacity configuration,so that the system configuration of the wind solar hydrogen storage project has a basis.Due to their different output characteristics,wind power output and photovoltaic output form a complementary trend,which plays a significant role in improving the utilization rate of hydrogen energy equipment and reducing hydrogen production costs.
