代码说明:

用C语言实现polyfit多项式拟合,已知离散点上的数据集,即已知在点集上的函数值,构造一个解析函数(其图形为一曲线)使在原离散点上尽可能接近给定的值。

  • 遗传算法求解日前调度
    用遗传算法求解电力系统简单日前调度问题,考虑微网发电成本的经济性,以微型燃气轮机发电成本、 储能运行维护成本和微网与主网之间买、卖电的交互成本为系统总成本,以电力平衡及机组运行的相关约束为模型的约束条件,建立使系统的总成本最低为目标函数的日前经济优化调度模型。 日前经济优化调度一般以 24 小时为调度周期,电网的调度中心根据次日调度周期内的负荷以及可再生能源出力预测数据,提前安排次日每个小时内发电机机组或储能设备等的出力情况以及要从上层电网购买或售出的电量,以达到发电成本最小或收益最大的目的。

  • Navicat Premium连接oracle远数据库(instantclient_12_3)
    【实例简介】instantclient_12_3.7z 【实例截图] navicat oracle library is not loaded Created by Marydon on 2018-08-09 19:23 1.情景展示   Navicat Premium 12连接Oracle时提示oracle library is not loaded 2.解决方案   这个还是instantclient版本低的原因造成的!   下载好新版本的instantclient,解压到Navicat的根目录下,重启Navicat。 3.测试   新建oracle连接-->连接名随便个名字,主机、端口号、数据库实例名称、用户名和密码      点“连接测试”-->正常情况下,连接成功   如果连接失败,查看oci.dll路径有没有发生变化   工具-->选项-->(环境)   变更oci.ll文件,需要重启Navicat      相关推荐: navicat ora-28547:connection to server failed Navicat Premium连接oracle远程数据库(instantclient_12_3) Navicat Premium 12.0.13 已破解免安装版   【核心代码】
