A Dynamic Power Flow Model Considering the Uncertainty of Primary Frequency Regulation of System

In view of the problem that uncertainty of primary frequency regulation (PFR) has not been considered in the existing research on the dynamic power flow, which may cause fault, this paper presents a stochastic dynamic power flow model that takes into account the uncertainty of the primary frequency regulation coefficient and the total adjustment amount of the AGC system, the switching process of allocation and control mode. By analyzing the uncertainties of primary frequency regulation coefficient and the regulation of AGC and AVC, as well as considering the active coordination equation of AGC unit with load frequency advanced control strategy, this model solves the problems of existing dynamic power flow model. The impact of the uncertain variables is addressed by the method of Monte Carlo simulation. Applying the proposed model to the IEEE 39-bus system to simulate the power flow distribution of cutting unit, load disturbance, and so on, the results prove that the model is practical and precise.
