摘要
应用微分同胚正规形理论,以非线性参与因子为依据,提出了确定实施负荷控制的地点及静止无功补偿(static var compensator,SVC)安装地点的更准确方法。分别以美国西部9节点系统、新英格兰39节点系统为算例进行了有功负荷控制和SVC安装地点分析,并采用电压稳定性指标以及动态仿真对系统的稳定性进行了检验。结果表明,微分同胚正规形方法能更好地反映电力系统的非线性特性,有效地确定实施负荷控制措施的地点以及SVC的安装地点。
Using the theory of normal forms of diffeomorphism and according to nonlinear participation factors, a more accurate method to decide the location to implement load control or the place to allocate static var compensator （SVC） is proposed. Taking load control in WSCC 9 bus power system and SVC allocation in New England 39 bus power system for examples, by use of voltage stability index and dynamic simulation the stability of these systems are verified. Results show that the normal forms of diffeomorphism theory can reflect the nonlinear characteristic of power grid better, and the location to implement load control and place to allocate SVC can be effectively decided.
