摘要

本文提出了一种氢储能系统工作于平抑风电波动模式下的典型运行曲线生成方法，并以此为依据优化储能系统功率与容量配置。通过EMD分解得到氢储能的充放功率时间序列曲线，依据不同时段特征参数的异同对曲线进行分类处理。分类后通过云模型得到每类曲线每时刻的典型充放电功率值，进而整合得到每类的典型运行曲线。在此基础上借助MATLAB CPLEX工具箱，以经济最优为目标对储能系统功率与容量进行优化。结合实测数据验证了本文提出的工况生成方法的有效性与合理性。

Abstract

In this paper, a typical-operation-curve generation method of a hydrogen energy storage system operating under the mode of stabilizing wind power fluctuations is proposed. This method is used to optimize the power and capacity configuration of the energy storage system. The time series curves of the charging and discharging powers of the hydrogen energy storage are obtained by EMD decomposition, and the curves are classified according to the similarities and differences of the characteristic parameters in different time periods. After the classification, typical charging and discharging power values of each type of curve at each moment are obtained by a cloud model, and then, typical operation curves of each type are obtained by integration. On this basis, the power and capacity of the energy storage system are optimized with the objective of economic optimization through the MATLAB CPLEX toolbox. Combined with the measured data of a wind farm with an installed capacity of 400 MW in Northeast China, the validity and rationality of the typical operation curve generation method proposed in this paper are verified.
