The increasing demand of load without considerable increase in transmission resources has posed numerous constraints and challenges in the power system monitoring and performance. The inadequacy in transmission resources has resulted in reduced operational margins for many power systems worldwide and has led to operation of power systems closer to their stability limits and to power exchange in...

The electrical structure of the power grid is utilized to address the phasor measurement unit (PMU) placement problem. First, we derive the connectivity matrix of the network using the resistance distance metric and employ it in the linear program formulation to obtain the optimal number of PMUs, for complete network observability without zero injection measurements. This approach was developed...

This letter a novel approach to event-based power modeling for embedded platforms that do not have performance monitoring unit (PMU). The method involves complementing the target hardware platform, where physical data is measured, with another platform on which CPU data, needed model generation, can be collected. methodology used generate accurate fine-grain models Gaisler GR712RC dual-core LEO...

A data compression system capable of providing real-time streaming high-resolution continuous point-on-wave (CPOW) and phasor measurement unit (PMU) measurements is proposed. Referred to as adaptive subband (ASBC), the proposed technique partitions signal space into subbands adaptively compresses signals based on each subband's active bandwidth. The conforms existing industry standards, making ...

This article develops a computationally efficient fault-detection method for power systems, by exploiting phasor measurement unit (PMU) data and Hessian locally linear embedding (HLLE) technique. First, via HLLE technique, high-dimensional PMU are transformed into low-dimensional coordinates, which effectively captures the fluctuations of data. Next, based on feature space T-squared statistic i...

In the recent years monitoring and operation of power system became complex, due to more demand from different linear non-linear loads generation sources. For effective system, existing methods need improve or new technologies are required. phasor measurement unit (PMU) based is suitable, because it provide dynamic state system. this paper PMU proposed with data storage protection. With method ...

Constantly growing distributed energy generation based on renewable sources creates a number of new challenges for electrical power system operation. One the is islanding detection. Unintentional islanding, which can cause health and safety hazards personnel, currently being experienced by consumers/prosumers especially in case photovoltaic inverters. This work presents detection method synchro...
