Abstract

In order to quantitatively assess the interaction between transmission levels and implement automatic calculation of limit power of multi-sections simultaneously

a coordinated limit power calculating method of multi-sections coupled with transient stability limit is proposed. The coupling mechanism is analyzed first

and a coordinated model for the dominant limit power of multi-sections to reach critical stability at the same time is developed. Then a quantitative method for analyzing the influence of simultaneous variation of multi-section transmission power on stability margin is proposed. An iterative algorithm based on the mathematical programming method for solving power increase step size is designed

which can be used for offline or online analysis and real-time monitoring of transmission limit power of multi-sections. The validity of this method is verified by an example of an IEEE 10-unit 39-bus system. This work is supported by State Grid Corporation of China
