摘要:

风-氢混合系统(W-HHS)参与电网调度时,氢储能系统(HESS)间歇工作的热能需求特性成为影响系统调度的关键因素。建立了具备余热利用系统的HESS模型,在HESS热量平衡和热功率平衡约束下,提出了以提高W-HHS运行收益为目标,满足混合系统输出功率跟踪电网调度曲线约束的W-HHS优化调度方法。最后,通过青海风电场数据对所提方法和模型进行了验证和分析。结果表明,HESS热平衡约束对W-HHS运行调度具有重要影响,所提方法能提高W-HHS运行的可靠性。参数分析说明,减小散热系数能够降低热平衡约束对W-HHS调度策略的影响,提高风电场并网功率。

Abstract:

When wind-hydrogen hybrid system (W-HHS) participates in grid,the heat demand characteristics of hydrogen energy storage system (HESS) working intermittently become the key factor affecting system dispatching.A HESS model with waste heat utilization system is established.Under the heat balance constraints composed of heat power balance and thermal energy balance of HESS,an optimal dispatching method of W-HHS is proposed to improve the profit and meet the constraints of tracking grid dispatching curve.Finally,the proposed model and method are verified and analyzed through an example of Qinghai wind plant data.The results show that the heat balance constraints of the HESS have an important impact on the operation and dispatching of the W-HHS.The proposed dispatching method improves the operation reliability of the W-HHS on the premise of ensuring the heat power balance and thermal energy balance of the HESS.Parameter analysis shows that reducing the heat dissipation coefficient can decrease the impact of heat balance constraints on the dispatching strategy of W-HHS and improve the grid connected power of wind plant.
