摘要: |
提出了一种基于小波包分解的风电混合储能容量配置方法。该方法对风电输出功率进行小波包分解,将其分解为低频部分和高频部分,采用低频部分作为并网目标功率,根据蓄电池和超级电容器的互补特性,分别用其平抑次高频部分和最高频部分。通过高斯逼近法拟合波动功率的概率密度函数,进而得出混合储能系统的容量。在Matlab/Simulink平台上搭建混合储能系统仿真模型。通过风电并网点输出功率的平滑程度以及混合储能系统荷电状态波动范围的分析,验证了该容量配置的有效性。 |

Abstract: |
This paper sets up a method of hybrid energy storage capacity configuration based on wavelet packet decomposition. Wind power is firstly decomposed into low frequency section and high frequency section by wavelet packet decomposition, and using low frequency section as the target of grid-connected power while high frequency section is divided into medium-high and highest on the base of the complementary property of battery and super-capacitor. Besides, the method of Gaussian approximation is adopted to fit the probability density function so that the capacity configuration of energy storage system can be calculated finally. The hybrid energy storage system simulation model is set up based on Matlab/Simulink. So the effectiveness of the capacity configuration can be verified by the fluctuation range and the state of charge (SOC) of energy storage system. |
