Patent number: 9780563Abstract: A distributed controller collects measurement value data of a voltage and a current in an own node and in another node; using the measurement voltage and the current of the own node and the measurement voltage and current of another node as input data, estimates a voltage or a current as a state quantity of the electric power system regarding another node from which the measurement value data cannot be collected, and outputs the estimate values; using the measurement data, the estimate value outputted from the state estimation functional unit and a voltage target value that has been set for each node, outputs the control commands for voltage controllers based on voltage change amounts to be distributed to the voltage control devices of the nodes including the own node. The voltages in the electric power system are controlled by superposition of voltage change amounts by the voltage control devices.Type: GrantFiled: February 28, 2013Date of Patent: October 3, 2017Assignee: Hitachi, Ltd.Inventors: Masatoshi Kumagai, Shota Omi, Kenichiro Yamane, Yasushi Harada, Masahiro Watanabe, Yasuo Sato, Yasushi Tomita

Publication number: 20170147023Abstract: Embodiments of the present disclosure relate to a time-skew correction unit and a method thereof. The time-skew correction unit classifies the electric grid into plurality of regions with one or more generators in said plurality of regions and obtains response time of one or more generators corresponding to each of the plurality of regions from a simulator. The time-skew correction unit further monitors the plurality of regions in real-time for predefined value of change of load data from one or more loads in the electric grid and determines time-skew offset for each of the plurality of regions based on the response time of the one or more generator and corresponding real-time data from the plurality of regions. Further, time-stamp of the real-time data from each of the plurality of regions is adjusted based on the time skew offset of corresponding plurality of regions for time-skew correction in the electric grid.Type: ApplicationFiled: November 22, 2016Publication date: May 25, 2017Applicant: HITACHI, LTD.Inventors: N.
