摘要
当考虑负荷电压静特性时 ,潮流方程不再为状态变量的二次函数 ,传统的求解病态潮流问题的最佳乘子牛顿法无法实施。该文提出了考虑负荷电压静特性的最佳乘子牛顿潮流算法。通过引入附加的状态变量并补充相应的潮流方程 ,使考虑负荷电压静特性后的直角坐标潮流方程仍保持为状态变量的二次函数 ,进而可以用最佳乘子牛顿法求解病态潮流问题。使用该方法能够保证潮流计算不发散 ,并且最佳乘子的求取同样简单、无近似 ,可以很容易地嵌入到常规的牛顿法潮流程序中 。
When taking into account of the voltage dependency of load characteristics,load flow equations are not quadratic function of state variables,optimal multiplier newton method of load flow solution for ill conditioned power system can not implemented.In this paper,optimal multiplier newton method of load flow solution with static load characteristics is presented.Load flow equations in the rectangular coordinates with static load characteristics remain quadratic function of state variables by using additional state variables and appending relative load flow equations,so load flow can be solved with optimal multiplier newton method.Using propose dmethod,the load flow solution never diverges,the calculation of optimal multiplier is very simple and no approximation,and can incorporated into normal newton program.The results of test systems show the validity and effectiveness of the proposed method.
