    • PROBLEM TO BE SOLVED: To suppress oscillation even though voltage oscillation occurs in a direct-current distribution system and stabilize the voltage of the direct-current distribution system. SOLUTION: A direct-current distribution system is so configured that direct-current power distributed from direct-current power supplies 1, 2 through a direct-current distribution line 3 is consumed at a load 4 having a power consuming source 6 through a power conversion device 5. In this direct-current distribution system, a voltage stabilizer is provided with a voltage oscillation suppression control unit 9 including an oscillation suppressing current command generation unit 21, and a load voltage control unit 10. The oscillation suppressing current command generation unit extracts an oscillating component form the direct-current system voltage of the direct-current distribution system and generates a current command value for suppressing this oscillation. Using this current command value, the voltage oscillation suppression control unit takes out an amount of control to cancel out the oscillating component of a load current flowing from the direct-current distribution system to the load. The load voltage control unit adds together this amount of control and a preset voltage value for supply to the load to obtain a final set voltage value, and then controls the power conversion device 5 so that the voltage of the load becomes equal to the final set voltage value.
