Description: matlab实验 用给定的多项式，y=x3-6x2+5x-3，产生一组数据(xi,yi，i=1,2,…,n),再在yi上添加随机干扰(可用rand产生(0,1)均匀分布随机数,或用rands产生N(0,1)分布随机数)，然后用xi和添加了随机干扰的yi作的3次多项式拟合，与原系数比较。
如果作2或4次多项式拟合，结果如何？
-matlab experiment with a given polynomial, y = x3-6x2+5 x-3, generated a set of data (xi, yi, i = 1,2, ..., n), then add random noise in yi (available rand generation (0,1) uniformly distributed random number, or rands generated N (0,1) random numbers), then xi and yi to add a random disturbance polynomial fitting for the three times, compared with the original coefficient . If 2 or 4 times for polynomial fitting, the result? Platform: |

Description: This paper presents a new method to solve the network reconfiguration problem in the presence of distributed generation (DG) with an objective of minimizing real power loss and improving voltage profile in distribution system. A meta heuristic Harmony Search Algorithm (HSA) is used to simultaneously reconfigure and identify the optimal locations for installation of DG units in a distribution network. Sensitivity analysis is used to identify optimal locations for installation of DG units. Different scenarios of DG placement and reconfiguration of network are considered to study the performance of the proposed method. The constraints of voltage and branch current carrying capacity are included in the uation of the objective function. The method has been tested on 33-bus and 69-bus radial distribution systems at three different load levels to demonstrate the performance and effectiveness of the proposed method. The results obtained are encouraging. (2014-11-17 Platform: |

Description: 假设微电网中有风、光、微型燃气轮机、蓄电池，且已知各时段负荷需求；微电网可并网运行，当微网内部发电量较大时，可向电网卖电，而当内部发电不足时，可从大电网购电，价格参考实时电价。考虑各机组运行成本、燃料成本、污染物处理成本、以及买卖电支出或收益。该程序可解决在并网运行模式下，各机组出力如何分配才能达到经济最优的问题。(Suppose there are wind, light, micro gas turbines and batteries in the microgrid, and the load demand is known at each time period; the microgrid can be connected to the grid for operation; when the microgrid has a large amount of internal power generation, it can sell electricity to the grid, and when the internal power generation is insufficient At that time, electricity can be purchased from the big grid, and the price can be referenced to real-time electricity prices. Consider each unit's operating costs, fuel costs, pollutant disposal costs, and trading power expenses or benefits. This procedure can solve the problem of how each unit's output can be distributed to achieve economical optimization in the grid-connected operation mode.) Platform: |
