CURRENT/VOLTAGE CONTROL SYSTEM

An object of the present invention is to provide a current/voltage control apparatus capable of following power changes in a DC system. A current/voltage control apparatus (1) according to the present invention includes a central monitoring control device (9) that controls V-I characteristics of a terminal converter (2, 3) based on power consumption consumed by a load facility (4) and generated power generated by a power generation facility (5), and the central monitoring control device (9) includes a load state setting unit (18) that predicts a change range of the power consumption in a predetermined period based on the power consumption at this time and the power consumption accumulated in a load result DB (13) and also predicts a change range of the generated power in the period based on the generated power at this time and the generated power accumulated in a power generation result DB (16) and a V-I characteristic determination unit (21) that determines the V-I characteristics of the terminal converter (2, 3) based on the change range of the power consumption and the change range of the generated power predicted by the load state setting unit (18).
