Modified Newton-Raphson load flow analysis for integrated AC/DC power systems

摘要: The significant increase in planned offshore wind parks and the tendency towards large considerable distances offshore, make well established HVDC technology a favorable solution for connection of these & distant to main power grid onshore. It is therefore necessary adequately model transmission links integrate them load flow analysis complete AC-DC system. In this paper, known Newton-Raphson method modified achieve compatibility systems with integrated DC AC network. elements residual vector Jacobian matrix network are kept unchanged merely complemented by new matrix, which represent modifications due link. equation includes real reactive at buses, their dependency on system variables. evaluated an test computation Matlab results presented.
