摘要
利用顺流及逆流网络方程提出一种确定电源与负荷功率分配关系的功率分解解析方法。该方法通过基本网络方程推导出分配系数矩阵、发电机出力矩阵和负荷矩阵的相互间的关系,并以此计算分配系数矩阵,建立了发电机对负荷分配及负荷对发电机分配的解析模型及求解算法。该方法直接表达了发电机出力与负荷功率间的解析关系。并且不需任何假设,通过对系统基本模型进行矩阵分析直接得到解析模型。该方法在IEEE三机九节点系统上进行了应用,其结果证实算法的有效性和正确性。
This paper proposes an efficient analytical method for power allocation, which makes sure of the power transferred between generators and loads using downstream and upstream network equations. First, the method induces the distribution factors matrix from basic network equations and makes the analytical relation of power transfer between generators and loads clear. Second, a distribution factors matrix is derived from those distribution factors so that the analytical model of power transfer between generators and loads can be built. The proposed method expresses directly and clearly the relation between generators and loads based on the basic power system model and no assumption on the distribution is needed. Here, analysis matrix is a key factor. Then,the proposed method is tested on the classical IEEE9-bus system. The results of computational example show that the developed technique is correct and useful. At last, the conclusions are given.
