基于实时的最优潮流提出一种合并的二级和三级电压控制方法,该方法能够周期性地刷新发电机电压调节器的参考电压。以最大负载能力为目标的最优潮流被用来实现所提控制方法。能够周期性地刷新发电机压调节器的参考电压。以最大负载能力为目标的最优潮流被用来实现此控制为法。所提技术的对比对象是"经典"的二级电压控制,其先导节点参考电压通过负载能力最大的最优潮流(三级电压控制)计算得到。在新英格兰10机39节点上所进行的不同运行条件和紧急状态下的时域仿真验证了所提二级和三级电压控制合并方案的有效性,并且展现了对于现有二级和三级电压控制的优势。
A combined secondary and tertiary voltage regulation (SVR+TVR) methodology based on real-time optimal power flows (OPFs)is proposed to periodically update the generators’ voltage regulator set points.A maximum loadability (ML) OPF approach is used for the proposed SVR+TVR control.The presented technique is compared against a "classical" SVR control,where the pilot-bus set points are determined by means of a ML-OPF-based TVR approach.Time domain simulations of the New England 10-machine 39-bus system for various operating conditions and contingencies are used to validate the proposed SVR+TVR technique,and to demonstrate its advantages with respect to existent SVR and TVR approaches.
