论文摘要
电力网络中平衡的稳定运行状态随时间变化。传统的功率流算法集中于在特定时间点下的稳定运行状态，并计算给定节点功率注射和网络拓扑的相应电压和功率分布。本文首先提出了用于时变功率流的线性时间间隔算法，该算法集中在时间间隔下的平衡操作状态，并通过时间变化功能在任何时间点计算电压和功率分布，通过该功能，功率流时间变化的过程在稳定的电力网络中很好地表示。在本文中，定义了有关节点功率注射的线性时间间隔，其中分析了节点电压衍生物和雅可比亚矩阵的规范，提出了一个合并的时间变化的节点电压功能，以及用于高度流动的高度流量的线性间隔算法，以实现远不复存在的范围，该范围是远不及的，以实现远不足的范围。动态时变问题。对IEEE 5总线和修改的118个总线系统的仿真案例研究证明了所提出的算法的有效性和效率。
Balanced steady operation state in power networks changes over time. Traditional power flow algorithm is focused on the steady operation state under a certain time point and calculates the corresponding voltage and power distributions for given nodal power injections and network topology. A linear-time interval algorithm for time-varying power flow is first proposed in this paper, which is focused on the balanced operation state under a time interval and computes the voltage and power distributions at any time point via a time-varying function, through which the power flow time-varying process is well represented in steady-date power networks. In this paper, a linear-time interval regarding nodal power injections is defined, in which the norms of nodal voltage derivatives and Jacobian matrix are analyzed, a combined time-varying nodal voltage function is proposed, and a linear-time interval algorithm for time-varying power flow with high accuracy is finally achieved, which is leveraged for simplifying the complexity of solving non-linear dynamic time-varying problems. Simulation case studies on IEEE 5-bus and modified 118-bus systems have demonstrated the effectiveness and efficiency of the proposed algorithm.
