摘要
针对微网“弃风”、“弃光”、“弃水”现象和日益增长的氢负荷需求,考虑在异地加氢站配置一定容量的制/储氢设备集中消纳微网余电。通过研究含风电、光伏、小水电及电解槽、储氢罐、重整器的微网-加氢站系统(MHSS)的拓扑结构和数学模型,建立以加氢站全生命周期总净现值成本最低为目标的制/储氢设备容量优化配置模型,并提出余电制氢-绿氢先行(RETH-GHF)的电氢联合运营模式。算例中,结合实际场景,运用自适应模拟退火粒子群优化(ASAPSO)算法进行仿真。通过对比微网余电异地集中/就地分散制氢方案的配置结果和成本收益明细,说明算例场景下异地集中制氢方案经济性更好,并考虑工业电价、氢气及天然气价格波动对加氢站全生命周期总净现值成本的影响,比较两种制氢方案的经济性,最后以四季典型日系统运行情况验证了加氢站制/储氢设备容量优化配置模型的合理性。
In view of the phenomenon of"abandoned wind power","abandoned photovoltaics"and"abandoned hydropower"in microgrids and the increasing demand for hydrogen load,a certain capacity of hydrogen production/storage equipment is considered to be deployed in the offsite hydrogen refueling station to centralize the consumption of surplus electricity from microgrids.Through the research of the topology and mathematical model of microgrid-hydrogen refueling station system(MHSS)containing wind power,photovoltaic,small hydropower,as well as electrolysis tank,hydrogen storage tank and reformer,a capacity optimization configuration model of hydrogen production/storage equipment with the objective of minimizing the total net present cost of the whole life cycle of the hydrogen refueling station is established,and the combined electric-hydrogen operation model for residual electricity to hydrogen-green hydrogen first(RETH-GHF)is proposed.In the example,the adaptive simulated annealing particle swarm optimization(ASAPSO)algorithm is applied to simulate the system with the practical scenario.By comparing the configuration results and cost-benefit details of offsite centralized/onsite decentralized hydrogen production schemes of microgrids,it is proved that the scheme of offsite centralized hydrogen production is more economical in the example scenario,and the economics of the two schemes of hydrogen production have been re-compared by taking into account the impact of industrial electricity price,hydrogen and natural gas price fluctuations on the total net present cost of the hydrogen refueling station throughout its life cycle,and finally,the rationality of the capacity optimization configuration model for hydrogen production/storage equipment in the hydrogen refueling station is verified with system operation of typical days in four seasons.
