考虑氢储供能时序的综合能源系统三阶段调度

Three-stage Scheduling of Integrated Energy System Considering Hydrogen Storage and Energy Supply Timing

为提高可再生能源的消纳水平,分析可调度能源价格对可再生能源消纳的影响,提出从源荷侧双角度结合的方法。源侧将机组分为可调度能源和可再生能源机组两部分,同时考虑光热电站、热电联产机组联合运行;荷侧考虑居民负荷和工业负荷,将工业负荷中氢储参与电能调度。结合电能三阶段调度,建立了考虑氢储供能时序的综合能源系统三阶段调度模型。模型以运行成本最低为目标函数,调用Matlab中SCIP求解器求解,结果表明,模型能够有效提升系统灵活性,促进可再生能源消纳,同时显著提高系统运行经济性。

To improve the consumption level of renewable energy,the impact of schedulable energy prices on renew⁃able energy consumption is analyzed,and a method considering both source and load is proposed.On the source side,the unit is divided into two parts,i.e.,a schedulable energy unit and a renewable energy unit.Meanwhile,the joint op⁃eration of a concentrating solar power and a combined heat and power unit is considered.On the load side,the residen⁃tial load and industrial load are taken into account,and the hydrogen storage in industrial load is used to participate in the scheduling of electric energy.Combined with the three-stage scheduling of electric energy,a three-stage scheduling model of the integrated energy system considering hydrogen storage and energy supply timing is established,which takes the lowest operating cost as its objective function and further solved by using the SCIP solver in Matlab.Results show that the proposed model can effectively improve the system’s flexibility and promote the consumption of renewable energy while significantly improving the system’s operation economy.
