Abstract
In an electric power system with a distributed power source, a fluctuation of its system voltage is brought about by an amount of power generation of the distributed power source that depends on weather. Stabilization of the system voltage is realized by generating a driving signal of a switch that the system has from weather forecast information and power system information and switching a configuration of the system.
Claims9
A system voltage stabilizer, comprising:
- an input part for inputting weather forecast information;
- and
- an instruction calculation part for obtaining an open/close instruction for connecting/disconnecting each of switches of a system so that a voltage fluctuation of the system affected by the air current fluctuation may be suppressed.
A system voltage stabilization method, comprising:
- inputting weather forecast information;
- and
- obtaining an open/close instruction for connecting/disconnecting each of switches of a system so that a voltage fluctuation of the system affected by a weather fluctuation may be suppressed based on the weather information, the inferred amount of power generation, and system configuration information.
