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 ...

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 ...

Traditional power system dynamic models are very complex due to the intricacy of power system networks and can be inaccurate for control because of the amount of details needed and the fact that the grid topology changes all the time. With the fast deployment of a large number of phasor measurement units (PMUs) in the transmission network, a purely measurement-based model for dynamics estimatio...

Phasor measurement units (PMUs) are considered as a promising tool for future monitoring, protection and control of power systems. In this paper, a novel approach is proposed in order to determine the optimal number and locations of PMUs to make the power system observable. The PMU placement problem is formulated as a binary integer linear programming, in which the binary decision variables (0,...

This paper proposes a novel online measurement-based Wide-Area Voltage Control (WAVC) method using Phasor Measurement Unit (PMU) data in power systems with Flexible AC Transmission System (FACTS) devices. As opposed to previous WAVC methods, the proposed does not require any model knowledge or participation of all buses and considers both active reactive perturbations. Specifically, exploits re...

Phasor Measurement Units (PMUs) are in growing attention in recent power systems because of their paramount abilities in state estimation. PMUs are placed in existing power systems where there are already installed conventional measurements, which can be helpful if they are considered in PMU optimal placement. In this paper, a method is proposed for optimal placement of PMUs incorporating conve...
