摘要(Abstract)：

基于电压源换流器的高压直流输电VSC-HVDC(voltage source converter based high voltage directcurren)t的引入使得潮流计算的变量增加,提高了潮流编程的复杂度。文中在含VSC-HVDC交直流系统的潮流算法基础上,结合自动微分AD(automatic differentiation)技术讨论了一种应用AD技术的交直流系统潮流计算方法。该算法利用AD自动生成潮流方程的雅克比矩阵,与传统的手工推导微分解析表达式再编写相应的微分代码方法相比,减少了手写代码量,显著提高了程序的开发效率。结合多个IEEE标准算例进行了仿真,分别对运行时间和收敛效果进行了比较,验证了算法的有效性。
