摘　　要：一体式再生燃料电池(unitized regenerative fuel cell,URFC)是一种集成了燃料电池发电与电解水制氢于一体的电化学装置,与风力、光伏发电相结合后,在并网型微电网系统中具有广阔的应用前景。为此,提出结合URFC、风电机组、光伏机组和传统电网的并网型微电网系统模型,并采用净现值作为衡量系统投资合理性的经济指标。以湖北地区某工业园区为研究对象,提出氢电供应因子用于协调并网型微电网系统的能源调度,并通过粒子群优化算法对系统进行设备容量优化和投资评估。结果表明:并网型微电网系统存在最优系统容量配置,当氢电供应因子为0.8时,微电网系统的净现值为最大值,具有良好的投资可行性。Unitized regenerative fuel cell(URFC)is an electrochemical device that integrates fuel cell(FC)and water electrolysis(WE).It has broad application prospects in grid-connected microgrid systems when combined with wind and photovoltaic power generation.Therefore,this paper proposes a model of grid-connected microgrid system combining URFC,wind turbine,photovoltaic unit and traditional grid,and adopts net present value(NPV)as an economic index for the reasonableness of system investment.A hydrogen supply factor is proposed to coordinate the energy dispatch of the grid-connected microgrid system in an industrial park in Hubei,and the particle swarm optimization(PSO)algorithm is used to optimize the capacity and evaluate the investment of the system.The results show that there is an optimal system capacity configuration in the grid-connected microgrid system.Meanwhile,when the hydrogen supply factor is 0.8 the NPV of the grid-connected microgrid system is the maximum value,which has good investment feasibility.
