摘    要:轨道交通系统作为用电大户,将光伏发电系统接入轨道交通牵引供电系统不但可以降低交通系统的运营成本,而且可以很好地实现节能环保.但因光伏发电具有随机性、不确定性,将光伏发电直接接入轨道交通牵引供电系统,将会对轨道交通牵引供电系统带来一定的冲击,精确的光伏发电预测是减少光电并网冲击的有效解决方法.首先,采用自适应粒子群算法提...

Abstract:Rail transit system is a big power consumer. Connecting photovoltaic power generation system to rail transit system can not only reduce the operation cost of transportation system, but also realize energy saving and environmental protection. However, due to the randomness and uncertainty of photovoltaic power generation, the direct access of photovoltaic power generation to rail transit power supply system will bring a certain impact on rail transit power supply system. Accurate photovoltaic power generation prediction is an efective way to reduce the impact of photovoltaic grid connection. Firstly, the adaptive particle swarm optimization algorithm is used to improve the optimization ability of the particles in the training of the historical data of photovoltaic power generation, and then the optimized parameters are substituted into the least squares support vector machine to predict the photovoltaic power generation load, which effectively ensures the accuracy of the prediction, and thus improves the stability of the photovoltaic power generation when connected to the rail transit power supply system.
Keywords:rail transit  PV generation  support vector machine(SVM)  forecasting
