摘要
对于目前储能系统中的双向BUCK-BOOST变换器,传统用的建模方法都是采用整数阶建模,而实际应用中电容电感都是分数阶的。因此基于分数阶微积分分别建立了充电和放电模式下的BUCK-BOOST变换器的模型,并且将所得的分数阶模型与传统的整数阶模型进行对比分析。表明该方法建立的模型能真实反映变换器的动力学行为,可以使以后的储能控制更加精确。
For the bidirectional BUCK-BOOST converter in the current energy storage system,the traditional modeling methods are all using the integer order modeling,while the capacitance and inductance in practical application are all of fractional order.Therefore,based on the fractional order calculus,the model of the BUCK-BOOST converter in charge and discharge mode are established respectively,and comparative analysis is made on the obtained fractional order model and the traditional integer order model.It shows that the model established by this method can truly reflect the dynamic behavior of the converter and make the energy storage control more accurate in the future.
