摘要
不可控的幅值突变是导致配电网主机无法精准跟踪源荷信号的主要原因,为解决这个问题,提出高比例新能源接入下配电网源荷自动跟踪方法.根据高比例电量输入比条件确定配电调度参数的取值范围,并联合相关电量传输信号,实现高比例新能源接入下的配电网源荷状态识别.根据配电网源荷阵列的数学表达式,提取源荷基波,确定跟踪向量的取值范围,从而完成高比例新能源接入下配电网源荷的自动跟踪.实验结果表明,应用所提方法可以避免源荷信号在单位传输周期内出现幅值不可控的情况,较好地解决了幅值突变造成的配电网主机无法精准跟踪源荷信号的问题.
Abstract
The uncontrollable amplitude mutation is the main reason why the distribution network host cannot accurately track the source load signal.To solve this problem,a method for automatic source load tracking in the distribution network under the high proportion of new energy access is proposed.Determine the range of distribution scheduling parameters based on the high proportion of electricity input ratio conditions,and combine relevant electricity transmission signals to achieve the identification of distribution network source load status under the high proportion of new energy access.Based on the mathematical expression of the distribution network source load array,extract the source load fundamental wave,determine the value range of the tracking vector,and thus complete the automatic tracking of the distribution network source load under the high proportion of new energy access.The experimental results show that the application of the proposed method can avoid the occurrence of uncontrollable amplitude of the source load signal within a unit transmission cycle,and effectively solve the problem of the distribution network host being unable to accurately track the source load signal caused by sudden amplitude changes.
