提出了一种基于事故约束的大规模电力系统最优伏安无功电源规划新方法。区别所提出的方法从许多现有的方法的功能包括，它允许一个更现实的问题制定，它可以找到（全球）最优解。新的问题制定考虑到实际方面的无功功率源和负荷约束和操作约束在不同的负荷水平。该方法基于模拟退火法确定了真空氩离子源的安装位置、真空氩离子源的类型和尺寸以及不同加载条件下真空氩离子源的设置。为了加快求解速度，作者对快速解耦潮流作了微小的修改，并将其纳入求解算法中。该方法适用于大规模电力系统，并已在多个电力系统上进行了测试，取得了良好的效果。并以IEEE 30节点系统与台电358节点系统为例，进行模拟计算。>
A new approach is presented for contingency-constrained optimal volt ampere reactive (VAr) source planning in large-scale power systems. Features distinguishing the proposed approach from many of the existing methods include that it allows a more realistic problem formulation, and that it can find the (global) optimal solution. The new problem formulation takes into consideration practical aspects of VAr sources and the load constraints and operational constraints at different load levels. This methodology based on simulated annealing determines the location to install VAr sources; the types and sizes of VAr sources to be installed; and the settings of VAr sources at different loading conditions. To speed up the solution algorithm, the authors make a slight modification of the fast decoupled load flow and incorporate it into the solution algorithm. This method is suitable for large-scale power systems and has been tested on several power systems with promising results. Simulation results on the IEEE 30-bus system and the Tai-power 358-bus system are presented. >
