摘　　要：利用可再生能源进行制氢和供电是提高微电网经济效益的手段之一。对氢电综合能源供应微电网进行优化调度,可提高系统供能可靠性和可再生能源利用率。建立了氢电综合能源供应微电网的系统结构,利用可再生能源电解水制氢供应氢负荷需求,通过储氢罐存储剩余氢能,采用燃料电池补充电负荷的不足。分析了可再生能源和负荷变化下的微电网运行模式,提出了保证供能可靠性的微电网综合协调调度策略。建立了以系统运行收益最大化为目标函数以及负荷失电和失氢率、弃风与弃光率等为约束条件的微电网优化调度模型。案例分析表明,提出的优化调度方法能够实现氢和电负荷的可靠供应,微电网可以获得较高的收益,同时可再生能源的利用率得到提高。A renewable-based microgrid has the potential to deliver both electricity and hydrogen,which is one of the means to improve its economic benefits.In this paper,we optimize the scheduling of hydrogen power integrated energy supply microgrid to improve the reliability of system energy supply and utilization of renewable energy.The system structure of the integrated hydrogen power supply microgrid is established,using renewable energy for hydrogen production by electrolysis of water to supply hydrogen load demand,storing surplus hydrogen energy through hydrogen storage tanks,and using fuel cells to supplement the shortage of electric load.The microgrid operation mode under the change of renewable energy and load is analyzed,and an integrated and coordinated microgrid dispatching strategy to ensure the reliability of energy supply is proposed.An optimal scheduling model of microgrid with system operation revenue maximization as the objective function and load loss and hydrogen loss rate,wind and light abandonment rate as the constraints is established.A case analysis shows that the optimal scheduling method proposed in this paper can realize the hydrogen and electric load supply increase the system revenue while the utilization rate of renewable energy is improved.
