摘要
Abstract
The integration of large-scale wind farms would influence the operation status of power system, which re-sults in the change of transient stability characteristic, so that it is very important to quantify the impact of wind farms for ensuring the wind power using and power system security. The power system transient stability risk assessment method considering large-scale wind farms is proposed in this paper based on the research of wind power model and grid failure severity. Based on the full consideration of the randomness of wind farm outputs and system failure states, the method employs the utility theory and takes the perceived utility of operator to relative angle deviation as the meas-ure index, and then, the nonlinear utility function is constructed to quantify the fault severity. Furthermore, the cal-culation method and flow chart of power system transient stability index are also provided in detail. This method is ap-plied to the New England 39-bus system, and the effect of different integration capacities and different integration points on system transient stability risk value is investigated. The simulation results show the effectiveness and correct-ness of the proposed method.关键词
