  • Patent number: 9606561
    Abstract: In formulating of a power generation operation schedule to a power grid network including multiple power plants and transformer stations, and, multiple batteries installed in association therewith, an operation planning system stores in advance power generation basic unit information of the power plant, and derivation information of the stored energy in the battery. Power generation basic unit information of the battery where power generation basic unit of the stored energy is added is set based on the power generation basic unit information of the power plant and the derivation information of the stored energy. While selecting a power generation facility from the power plants and the batteries in an order of a smaller value indicated by the power generation basic unit information, the power generation quantity of the selected power generation facility is added to a total power generation quantity until the total power generation quantity matches a demand quantity.

  • Patent number: 9202187
    Abstract: A plant operation support system of one embodiment includes a condition setting unit, a characteristic data storage unit, and a predicting unit. The condition setting unit sets a power supply amount to be supplied from the plant to an outside, and a target recovery rate of carbon dioxide to be generated by the thermal power generation facility. The characteristic data storage unit stores characteristic data representing a capability of recovering carbon dioxide by the carbon dioxide recovery facility, which varies according to operating output of the thermal power generation facility. The predicting unit predicts a fuel consumption amount in the thermal power generation facility and a recovery amount of carbon dioxide in the carbon dioxide recovery facility based on contents set by the condition setting unit and contents stored in the characteristic data storage unit.

  • Publication number: 20140330442
    Abstract: A power supply curve matching one of the patterns of a demand curve stored in advance is created by combining power generation quantities of various power sources. An environmental load index to a supply quantity indicated by the supply curve is calculated based on environmental load information stored in advance. Next, reducible quantity information for each power consumption reduction characteristic of each consumer is stored in advance, a necessary reduction quantity to cause the supply curve to match a predetermined curve is calculated. A reducible supply quantity is calculated based on reducible quantity information, and a reducible index obtained by dividing the reducible supply quantity by the necessary reduction quantity is calculated. Next, the supply curve is adjusted until it is determined that both environmental load index and the reducible index are within respective certain ranges.

  • Publication number: 20140207502
    Abstract: According to one embodiment, there is provided a power generation facility information management system including a power generation variation information analysis unit configured to analyze information about the form of a stop of power generation, and information about the form of a variation in the power generation amount, thereby analyzing the possibility of reduction of an environmental impact caused by the power generation. The system includes a calculation unit configured to calculate the reduction amount of the environmental impact when the stop in an avoidable power generation stop period is assumed to be avoided and calculate the reduction amount of the environmental impact when the avoidable variation is assumed to be avoided, based on the analysis result.
