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)

滤波法
A、名称：限幅滤波法（又称程序判断滤波法）
B、方法：
根据经验判断，确定两次采样允许的最大偏差值（设为A），
每次检测到新值时判断：
如果本次值与上次值之差<=A，则本次值有效，
如果本次值与上次值之差>A，则本次值无效，放弃本次值，用上次值代替本次值。
C、优点：
能有效克服因偶然因素引起的脉冲干扰。
D、缺点：
无法抑制那种周期性的干扰。
平滑度差。(A. Name: Limited filter method (also known as program judgement filter method)
B. Method:
Based on experience, the maximum allowable deviation (set to A) of two sampling times is determined.
Judge each time a new value is detected:
If the difference between the current value and the previous value is <=A, the current value is valid.
If the difference between the current value and the previous value is greater than A, then the current value is invalid, abandon the current value and replace the current value with the last value.
C. Advantages:
It can effectively overcome the impulse interference caused by accidental factors.
D. Disadvantages:
That periodic interference cannot be suppressed.
The smoothness is poor.)

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.)
