Patent number: 9425606Abstract: An information communication device is provided with a monitoring unit, a communication unit, a storage unit, a switching unit, an acquisition unit, a creation unit, and a transmission unit. In the event that the monitoring unit detects trouble in the basic network, the switching unit switches the communication function of the communication unit from a first communication function to a second communication function. In the event that the monitoring unit detects trouble in the basic network, the creation unit creates notification information about the trouble in the basic network. The transmission unit transmits the created notification information via the switched-to communication function to a contact retrieved from the storage unit.Type: GrantFiled: March 12, 2013Date of Patent: August 23, 2016Assignee: KABUSHIKI KAISHA TOSHIBAInventors: Yoshihiro Yamaguchi, Ryo Yano, Keiko Mori, Mitsukage Yamada, Michiyo Ogino, Yoshihiro Ogita

Patent number: 8774979Abstract: According to one embodiment, there is provided an executive monitoring and control system for monitoring and controlling a power generation output of each dispersed power source and a load of each demand facility in a smart grid or a micro grid. An abnormal-time interchange procedure formation unit forms, when a fault occurs in a system, an interchange procedure of matching the total power generation output amount of dispersed power sources with the total loading of demand facilities, by using at least the information acquired by the measurement value monitoring unit and the information managed by the customer information management unit.Type: GrantFiled: February 27, 2012Date of Patent: July 8, 2014Assignee: Kabushiki Kaisha ToshibaInventors: Ryo Yano, Yoshihiro Ogita, Akinori Nishi, Takenori Kobayashi

Patent number: 8554383Abstract: A power supply and demand control apparatus includes a power generation planning unit that calculates one day's power outputs of multiple distributed power sources and a power flow target of a linking point to another power system, a long-cycle control unit having a long-cycle supply-demand balancing control unit that performs control every few minutes so as to ensure the supply-demand balancing of electric energy in a given amount of time at the linking point in order to perform control for making deviations between total power output calculated by the power generation planning unit and load power in the power system constant, and a short-cycle control unit having a short-cycle supply-demand balancing control unit that performs similar control every few seconds. In the power supply and demand control apparatus, the long-cycle control unit and short-cycle control unit perform the supply-demand balancing control in a hierarchical fashion to determine output assignments of the distributed power sources.Type: GrantFiled: April 9, 2009Date of Patent: October 8, 2013Assignee: Kabushiki Kaisha ToshibaInventors: Koji Toba, Takenori Kobayashi, Yoshihiro Ogita, Akinori Nishi
