本文提出了一个弱的总线导向的标准，以确定候选总线安装新的无功电源的无功规划问题。首先，一个有效的方法，使用电压崩溃接近指标，描述了用于识别弱总线。在这些薄弱节点进行适当的无功规划，可以提高系统的安全裕度，特别是防止电压崩溃。接下来，目标实现（GA）方法的基础上的模拟退火（SA）的方法被施加到解决一般的多目标无功规划问题，假设决策者（DM）有目标的每个目标函数。该方法既能得到较好的最终解，又能缩小解空间.所提出的方法的AEP-14总线系统，以及一个大的，实际尺寸的系统的应用结果也被提出。
This paper presents a weak bus-oriented criterion to determine the candidate buses for installing new VAr sources in the VAr planning problem. First, an efficient method, using a voltage collapse proximity indicator, is described for identifying weak buses. Then appropriate VAr planning in those weak buses can enhance the system security margin, in particular, to prevent voltage collapse. Next, the goal attainment (GA) method based on the simulated annealing (SA) approach is applied to solving general multi-objective VAr planning problems by assuming that the decisionmaker (DM) has goals for each of the objective functions. The presented method can both obtain a better final solution and reduce the solution space. Results of application of the proposed method to the AEP-14 bus system as well as to a large, actual-size system are also presented.
