  • Microgrid control system
    Patent number: 9742189
    Abstract: The present invention relates to a system for controlling microgrid facilities. In particular, the microgrid control system provided is capable of controlling multiple facilities according to characteristics of the facilities in order to achieve economic efficiency, environmental friendliness, and continued operability. The microgrid control system for controlling the operations of the multiple power facilities is provided with: a power supply activation/suspension planning unit that has a prediction unit for predicting outputs or loads of power supply facilities or load facilities and a prediction unit for predicting prediction errors contained therein; and an economical load allocation unit that determines command values related to the distribution of loads to be borne by currently running power supply facilities.
    Type: Grant

  • Substance detection method and substance detection apparatus
    Publication number: 20040028560
    Abstract: A substance detection method includes the steps of: heating a sample adhered to a substance with a temperature at which the substance is readily vaporized to vapor the substance; sucking air and feeding the sucked air in a direction different from a direction along which the substance is vaporized; negatively ionizing the vapor sucked with the air; and detecting the substance adhered to the sample by analyzing the negative ion.
