摘要
为解决偏远海岛能源运输成本高、化石燃料机组污染排放严重等问题,该文以孤岛微电网为研究对象,建立了基于可逆固体氧化物电池的电热氢耦合孤岛微电网双层容量规划模型,对微电网内的新能源发电机组、可逆固体氧化物电池、储氢库和电制热设备进行容量规划。首先,基于外围热辅助系统建立了包括发电工况、电解工况、热备用工况和停机工况在内的可逆固体氧化物电池四工况运行模型,提升微电网系统运行灵活性。其次,对可逆固体氧化物电池的动态转换效率与电堆热平衡进行精细化建模,提高规划结果的准确性。然后,考虑可逆固体氧化物电池余热回收参与海岛热负荷供应,实现孤岛微电网的电热氢一体化建设。最后,基于源荷侧不确定因素相关性进行随机场景生成,将孤岛微电网设备容量规划决策与典型日运行调度相结合,利用鲸鱼优化算法和CPLEX求解器对双层模型进行求解。仿真结果表明,该文所提基于可逆固体氧化物电池的孤岛微电网规划模型能有效提高孤岛微电网运行的经济性与灵活性。
To solve the problems of high energy transportation costs and serious pollution emissions from fossil fuel units in remote islands,this paper takes the island microgrid as the research object,establishes a double-layer capacity planning model of electric-thermal-hydrogen coupled isolated microgrid based on a reversible solid oxide cell.The capacity planning of new energy generators,reversible solid oxide cells,hydrogen storage tanks,and electric heating equipment in the island microgrid is carried out.Firstly,a reversible solid oxide cell operating model is established based on the peripheral thermal balance plant,including four operating conditions:power generation condition、electrolysis condition、hot standby condition,and shutdown condition to enhance the operational flexibility of the microgrid system.Secondly,refined modeling of the dynamic conversion efficiency and stack thermal balance of the reversible solid oxide cell is conducted to improve the accuracy of planning results.Then,consider the participation of reversible solid oxide cell waste heat recovery in island heat load supply,achieving the integrated construction of electric-thermalhydrogen in island microgrids.Finally,random scenario generation is carried out based on the correlation of uncertain factors on both the source and load side and the capacity planning decision of islanded microgrid equipment is combined with typical daily operation scheduling.The double-layer model is solved using a whale optimization algorithm and CPLEX solver.The simulation results show that the island microgrid planning model based on reversible solid oxide cell proposed in this paper can effectively improve the economy and flexibility of islanded microgrid operation.
