This paper presents a new approach for wide area dynamic monitoring of the system with many possible applications. One such application is discussed to provide real time stability controls. The new approach utilizes a substation based dynamic state estimation. The substation based dynamic state estimation uses data from relays, PMUs, meters, FDRs etc in the substation only thus avoiding all issues...
A universal GPS synchronized meter is presented, intended for use in smart grid applications. A high fidelity real time monitoring system that enables full awareness of the system status and the operating conditions is achieved. The meter consists of an energy harvester, voltage and current sensors, a GPS receiver, a microprocessor, and a wireless communication component. The device makes use of the...
This paper provides a methodology to extract the dynamic real time model of an electric power system using phasor measurement unit (PMU) data (GPS-synchronized) and other SCADA data that are available in substations. In addition to typical voltage and current measurements, PMU data include frequency and rate of change of frequency. Such data are available in raw form, as time-stamped instantaneous...
