Decentralized Power Modulation of Multiterminal HVDC Systems

This paper appLies a new method of control design for decentralized power modulation of multiterminal hvdc systems. The feedback structure uses only local output variables which are directly available without observer action. The feedback gains are computed to assign closed loop eigenvalues of the Linearized system for any specified modes. A computer simulation of an integrated ac/dc power system demonstrates resulting control performance; for typical disturbances. Comparisons are made with centralized modulation and several designs with limited communications.
