Self-Powered Global Positioning System (GPS)-Synchronized Micro-Continuous Point-on-Wave (CPoW) Module
­Background Electric power utilities have started using phasor measurement units (PMUs) to obtain time-synchronized measurements of the voltage and current magnitudes and phase angles, frequency, and rate-of-change frequency (RoCoF) throughout their systems. However, there are still several key measurements that PMUs are unable to provide. In particular,...

Effective Feature Set–Based High Impedance Fault Detector
Background High impedance fault (HIF) normally occur in distribution power systems with voltages ranging from 4 kV to 34.5 kV, and are caused by downed or disturbed conductors. An HIF may present a hazard to public safety in the immediate vicinity. Unfortunately, HIFs cannot always be recorded in the fault report to relay engineers and are thus susceptible...

The Induced Markov Chain Forecasting Method for Wind Farm Generation and Automatic Parameter Selection Procedure
Wind turbines are becoming an increasingly common source for energy, yet they can only generate output energy based on the current wind speed causing uncertainty during power system operation. To manage with this uncertainty wind power forecasts are used to predict energy output using statistical models and meteorological data. Statistical models are...
