牛顿－拉夫逊法潮流计算 基本步骤： 　　（1）形成节点导纳矩阵 　　（2）将各节点电压设初值U， 　　（3）将节点初值代入相关求式，求出修正方程式的常数项向量 　　（4）将节点电压初值代入求式，求出雅可比矩阵元素 　　（5）求解修正方程，求修正向量 　　（6）求取节点电压的新值 　　（7）检查是否收敛，如不收敛，则以各节点电压的新值作为初值自第3步重新开始进行狭义次迭代，否则转入下一步 　　（8）计算支路功率分布，PV节点无功功率和平衡节点柱入功率。(Newton-Raphson method flow calculation basic steps : (1) formation of nodal admittance matrix (2) to set up the initial node voltage U, (3) the initial node-generation-related demand. calculated that the constant term formula Vector (4) nodes will be incorporated into the initial voltage-seeking, calculated Jacobian matrix elements (5) solving that equation, seek to amend the vector (6) to strike a new node voltage value (7) to check whether convergence, if not restrained. concentrated in the nodes of the new voltage as the initial value since the first three steps to re-start the narrow iterations. Otherwise, turn into the next (8) Calculation branch power distribution, PV nodes reactive power and balance-node into power.)

Hopfield网络是一种典型的单层反馈网络，这种网络可以分为离散型和连续型两种，Hopfield网络是一个动力学系统，在确定连接权重后，若输入某个向量之后，网络将不断演化，一般情况下系统将趋向某一个定态，称为状态空间的不动点吸引子。-Hopfield network is a typical single-layer feedback network, Such networks can be divided into discrete and continuous two, the Hopfield network is a dynamic system, In determining the weights link, and if the importation of a certain vector, the network will continue to evolve Under normal circumstances a system will tend to a steady state, as the state space of fixed point attractor.
