实现含风电场RX模型的系统潮流计算，风电场采用RX模型，此模型充分考虑风力发电机的输出功率特性，比其他模型完善，在模型中将迭代过程分为两步:常规潮流迭代计算和异步风力发电机的滑差迭代计算。( In short, the algorithm carried out to simulate the wind farmas an RX bus is as follows: 1)Begin with s=snorm in each machine, snorm being the rated slip of the same. With this value, calculate the impedance Z. 2)With these values, model the wind farm as an RX bus including the admittances of the machines in the admittance matrix and in the corresponding terms of the jacobian. 3)As a result of the first power flow, the voltages in the buses can be obtained. With these, can calculate the mechanical power of the machine. 4)With the value of s, calculate the power extracted the wind with . 5)Compare both powers and, if they are not equal, recalculate，by means of (G) and go to step 2. If they are equal, he algorithm finishes.)

本例主要说明了空间域滤波与频域滤波的比较！在空间域中采用了Sobel掩膜对f滤波的结果与在频域中进行等价操作的结果！(This example illustrates the spatial filtering mainly with the comparison of frequency domain filtering! In the spatial domain using the Sobel filter mask on the results of f in the frequency domain is equivalent with the result of the operation!)

以Griewank函数为测试对象，应用PSO算法优化求解(Use Griewank function for test object, apply PSO algorithm as the optimal solution)

For example, heating up the temperature in a room is a process that has the specific, desired outcome to reach and maintain a defined temperature (e.g. 20°C), kept constant over time. Here, the temperature is the controlled variable. At the same time, it is the input variable since it is measured by a thermometer and used to decide whether to heat or not to heat. The desired temperature (20°C) is the setpoint. The state of the heater (e.g. the setting of the valve allowing hot water to flow through it) is called the manipulated variable since it is subject to control action
