Java人机对战五子棋游戏FiveChessGame设计思路： 　　1、用按钮做棋子，用图片填充每个按钮。 　　2、棋盘为24*24的 　　FiveChessGame类的构造方法。主要设置JFrame的相关属性、棋盘初始化方法initChess(JButton[][] chess),设置棋子的相关属性，图标、大孝事件等。点击棋子时设置棋子的图标setOnChessIcon，根据判断该位置的棋子是否有棋子，和棋子颜色设置棋子图标，将棋子放入panel中addChessIntoPanel(JButton[][] buttons,JPanel panel)，把panel设置为网格布局，然后向里面添加棋子JButton:chess。 　　响应按钮的事件actionPerformed(ActionEvent e)根据点击的按钮，获取其ActionCommand，然后找到对应的棋子chess[x][y]，并作出相应的响应事件。判断棋子是否嬴了，并给出相应的操作。嬴了调用getWinDialog()弹出提示栏。

配电网中有分布式电源，当发生故障时，可对配电网进行孤岛划分，本程序可实现该功能，包括源程序和输入文件(Distribution network with distributed power, when a failure occurs, the distribution network can be divided island, the program can achieve this functionality, including source code and input files)

针对风电场输出功率的强波动性对交直流互联电网调频的影响，提出了基于协作式分布式模型预测控制的交直流互联电网调频控制方法，以提高风电经交直流通道外送互联系统的频率稳定性，克服集中式模型控制方法扩展性差的缺点，该控制策略具有全局最优解。(Aiming at the influence of strong fluctuation of wind farm output power on frequency modulation of AC/DC interconnected power grid, a frequency modulation control method for AC/DC interconnected power grid based on cooperative distributed model predictive control is proposed to improve the frequency stability of wind power interconnected system via AC/DC channel and overcome the poor expansibility of centralized model control method. The disadvantage of this control strategy is that it has a global optimal solution.)
