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.)

网吧管理软件，希望能给大家点帮助，里面有些地方须大家给检查一下(Internet management software, we hope that they will help point, where some of the areas that need to check everyone)

配电网重构是一个多目标、多时段、多组合、多约束的非线性优化问题。该问题的复杂性，决定了难以用单纯的数学方法得到满意的解。尝试用改进的遗传算法进行配电网络重构，建立评价函数，寻求该评价函数最优解(Distribution network reconfiguration is a multi-objective, multi-slot, multi-portfolio, multi-constrained nonlinear optimization problem. The complexity of the issue, a difficult decision purely mathematical methods satisfactory solution. Try to use improved genetic algorithm for distribution network reconfiguration, the establishment of the evaluation function, evaluation function to find the optimal solution)

本程序时基于混沌理论和ELMAN神经网络的短期负荷预测，能取得很好的预测效果，直接使用该程序就能实现电力短期负荷预测，同样使用于其他类型的时间序列预测(the procedures based on chaos theory and neural networks ELMAN short-term load forecasts, can be achieved very good results forecast, the direct use of the procedure we will be able to realize short-term power load forecasting, the same used in other types of time series prediction)
