摘　　要：以弱节点作为无功补偿装置的最佳配置地点,提出了一种基于过渡状态的无功补偿装置最优配置问题的改进数学模型。该模型同以往模型的不同之处在于对安全性问题的考虑,直接将电压崩溃和恢复控制以费用函数来表示,并体现在目标函数中。求解该模型是一个混合整数非线性规划问题,采用多种群遗传算法来进行优化,避免了采用Benders 分解带来的解的发散问题。对AEP14节点系统的计算结果表明,文中的优化方法具有较强的工程实用性。Taking the weak buses as the optimal allocation places, an improved mathematical model for optimal allocation of reactive power compensating devices based on transition states is proposed. The difference between the proposed model and existing models is that the security problem is taken into account, the voltage collapse and corrective controls are directly expressed by cost function and incarnated in objective function. Solving the proposed model is a mixed integer nonlinear programming problem and is opt...
