Prediction Algorithm of Steady Frequency After Disturbances Considering Emergency DC Power Support
摘要
Abstract
A prediction algorithm of steady frequency after disturbances for AC/DC hybrid power grid is proposed, which takes into consideration the emergency DC power support(EDCPS) and the frequency response of the AC systems on both sides of the DC link.With the linearization of the generator governor equation, the static load model equation, the transmission power equation of DC transmission system, and the network equation of power system, the prediction equation of steady frequency after disturbances in a two-area AC/DC hybrid transmission system is derived by taking EDCPS into consideration.The steady frequency after disturbances in every area of the two-area AC/DC hybrid transmission systems can be quickly and directly calculated, so that the amount of DC power support will make the steady frequency of one area reach a set value.Finally, a typical two-area AC/DC parallel hybrid transmission system is simulated.And the simulation results show that the proposed algorithm has a high accuracy and a rapid computation speed, which proves its applicability and effectiveness as well as prospects of coordinating with emergency frequency control and online application.关键词
