Abstract

Many studies on static frequency characteristics have been done yet nodal dynamic frequency response characteristics gain more attentions for the important role frequency plays in power system stability. Influencing factors such as balance power, power shortage and electrical distance are altered during PSASP simulation of IEEE36 bus system to acquire diverse sampling points and relevant K values. Modified curved surface fitting obtained by the K values can both be used to forecast K values under any circumstances and simultaneously analyze the influencing effect. The method is proved to be feasible by analyzing the errors between simulation values and fitted values and it can offer reference for dispatch department to process the frequency variation caused by the power disturbance.
