摘要 针对交互作用引起的多控制器协调设计问题,提出基于BAB方法的控制环选择法。该方法选择出的控制环对相应弱阻尼或负阻尼模式有较大可控可观性,同时交互作用足够小,因此各控制器参数独立设计即可达到多控制器协调的目的。在考虑时滞电力系统模型的基础上,建立了多控制器控制环选择模型。所提方法包括:适用于求解控制环选择的多目标组合优化问题的BAB方法和从BAB法得到的Pareto最优控制环集中选择最适控制环的方法。最后以2区域4机系统和新英格兰10机39节点系统为例进行测试,验证了该方法的有效性,而且在这些控制环基础上独立设计的控制器具有很好的多控制器协调效果。

Abstract:This paper proposed a controller loops selection method based on branch and bound (BAB) method, for the problem of multi-controller coordination caused by interactions. The loops selected can provide not only large controllability and observability of the corresponding weak or negative mode, but also the small enough interactions between loops. As a result, independent design of each controller parameter can achieve the goal of multi-controller coordination. Firstly, this paper builds the multi-controller control loops selection model based on power system model with time delay. And then, a controller loops selection method based on BAB method is provided, which can solve the problem of multi-objective combinatorial optimization. The method to select the most suitable solution is also proposed according to the specific environment from the Pareto-optimal set obtained by BAB method. At last, the 2-area 4-machine system and the New England 10-machine 39-bus system are adopted as test system. It is shown that the proposed method can select the control loops with large controllability and ovservability, and has small enough interactions. In addition, the independently designed controllers based on these loops have good coordination effects.
