Capacity configuration of distributed home energy system based on hydrogen energy

针对分布式新能源作为独立电源向家庭能源系统供能存在的不稳定性问题,提出了一种基于氢能的分布式家庭能源系统容量配置方法。该方法基于氢能可平抑风光波动、灵活性转化负荷需求等特性,构建了氢能耦合分布式能源的家庭终端能源系统结构,结合地区可再生资源特性,以净现总成本为目标建立了基于氢能的分布式家庭能源系统容量配置模型。以新疆地区的风光资源和典型家庭用能数据为例,仿真分析了分布式能源与氢能系统配置容量大小对系统的影响,得到了最优风光配比条件下氢能系统的最佳容量配置。由仿真结果可知:所提模型能够在实现家庭能源系统离网可靠供能的条件下有效降低系统的总成本,促进新能源消纳,为基于氢能的分布式家庭能源的设计提供了建议。

In response to the instability problem of distributed new energy as an independent power source supplying energy to household energy systems,a capacity configuration method for distributed home energy systems based on hydrogen energy is proposed.This method is based on the characteristics of hydrogen energy that can suppress wind and solar fluctuations and flexibly convert load demands,and constructs a hydrogen coupled distributed energy family terminal energy system structure.Combining with the characteristics of renewable resources in the region,a hydrogen based distributed household energy system capacity allocation model is established with the goal of minimizing the net total cost.Taking the wind and solar resources and typical household energy data in Xinjiang region as an example,the impact of the configuration capacity of distributed energy and hydrogen energy systems on the system is simulated and analyzed,and the optimal capacity configuration of hydrogen energy systems under the optimal wind and solar ratio conditions is obtained.From the simulation results,it can be seen that the proposed model can effectively reduce the total cost of the household energy system while achieving reliable energy supply off the grid,and promote the consumption of new energy,which provides suggestions for the design of distributed household energy based on hydrogen energy.
