摘要:

光伏出力具有不稳定性、波动性、间歇性的特点,大量并网将不利于电网稳定,采用储能解决上述问题,提出了基于PSO-BP神经网络的光伏出力波动平抑模型。在获得光伏电站典型出力曲线的基础上,通过优化一阶低通滤波器的时间常数,获得储能配置相关参数。仿真结果表明,与BP神经网络相比,PSO-BP神经网络模型可以获得更佳的时间常数。

Abstract:

Photovoltaic power has the characteristics of instability,volatility,intermittent,a large number of grid-connected will not be conducive to the stable,energy storage device can solve the above problems.In this paper,a PV output fluctuation suppression model based on PSO-BP neural network is proposed.On the basis of obtaining the typical output curve of photovoltaic power station,the relevant parameters of energy storage configuration are obtained by optimizing the time constant of first-order low-pass filter.The simulation results show that compared with BP neural network,PSO-BP neural network model can obtain better time constant.

Key words: photovoltaic output, smooth fluctuation, PSO-BP neural network, filter
