Abstract This paper presents a method which uses adaptive BP(ABP) network to fit the relationship between the proportion of dynamic load and the active power P_L, reactive power Q_L, voltage U_L, frequency f_L of the transmission line, equivalent power P_G of Equivalent generalized load, then uses the trained ABP to identify β in transient stability analysis. This method firstly creates the equivalent generalized load model of the regional power system; secondly, changes the β to form the training data of ABP; finally uses thes trained ABP to identify β in transient stability analysis of the regional power grid. Simulation results on CEPRI 36 nodes system and power grid of Qingshan show its feasibility and effectiveness.

Key words： Adaptive BP network generalized load equivalence identification of the proportion of dynamic load
