Abstract

This paper continues the effort to define load impedance specification for a stable DC distributed power system. To improve the existing load impedance specification, an alternative forbidden region for Z₀/Z_i is proposed, based on which individual impedance specification for each load is defined. Theoretical verification, accompanied with simulation results, shows that the proposed impedance specification is a sufficient condition for small signal system stability. Finally, conservativeness in load impedance specification is discussed
