基于用户侧能源转换设备的综合能源系统可靠性分析
|
摘要
综合能源系统作为未来供能系统发展趋势,定量考虑能源转换设备对可靠性的影响,对于指导综合能源系统的规划与运行有着重要的意义。该文考虑不同供能网络的安全准则,采用变步长重复潮流法,求解故障情况下满足综合能源系统安全性约束的转换设备转供能力。在此基础上,对不同用户供能质量需求进行分类,建立综合能源系统的可靠性评价体系,利用序贯蒙特卡洛模拟法进行可靠性评估。以某园区热电联供系统为例,验证所提评价体系的可行性及有效性。结果表明,可靠性指标与能源转换设备的配置节点、配置容量以及能效比有关,可靠性评价体系为能源转换设备规划提供了理论依据。
As the future trend of energy supply systems, it is very important to consider the impact of energy conversion equipment on the reliability analysis for the integrated energy system(IES) planning and operation. In this paper, the repeated power flow method is employed to find the transfer capability of conversion components satisfying the safety constraints of IES while considering the safety criteria of different energy supply networks. Then, the IES reliability assessment indices are established based on the different user classification according to the energy demand quality. The IES reliability evaluation is performed using the sequential Monte Carlo simulation method. Finally, the proposed method is validated on a combined heat and power system. Results indicate that the IES reliability index is related to the capacity, location and energy efficiency ratio of energy conversion equipment. The reliability evaluation system provides a theoretical basis for energy conversion equipment planning.
