The traditional optimal reactive power planning(ORPP)seeks the optimal compensation scheme based on the normal operating mode,which is difficult to satisfy the restriction of voltage security in the N-1 mode.
为解决传统无功规划以正常运行方式来寻求无功补偿方案的优化,往往不能满足系统在N-1事故方式下的电压安全性问题,为此提出了基于N-1方式的无功优化规划的数学模型,以系统发生N-1事故后的网络运行方式为对象,以系统年支出费用最小为目标函数,并满足各种物理约束和运行约束,从而能够保证系统在出现N-1事故时仍有足够的无功备用来维持电压安全水平。
