| 摘 要： | 利用配电网实时量测数据和规格化的负荷历史数据,以各负荷的有功功率和无功功率的增量作为状态量,使状态量与目标函数近似线性关系,在小区间内迭代线性最小二乘法逐次逼近非线性关系,在线估计配电网用户的实时负荷。通过IEEE典型算例验证该方法可行。

| Abstract: | Based on real time measurement data and normalized history load data of distribution system,incremental of load active and reactive power are used as quantity of states to make sure the linear relationship between quantity of states and objective function,linear least-squares algorithm in microregion are iterated to approach nonliear relationship,and cunsumer load of distribution system are online estimated.The algorithm is proved feasible by IEEE typical examples. |
