In this paper, we propose a novel approach for the data-driven characterization of power system dynamics. The developed method Extended Subspace Identification (ESI) is suitable systems with output measurements when all dynamics states are not observable. It particularly applicable dynamic identification using Phasor Measurement Units (PMUs) measurements. As in case systems, it often expensive ...

In this paper, frequency oscillation has been present as it is an important issue in power systems, especially when joined to the new trend use alternative energies energy source, well be a big risk for inter-connection of modern electric networks. Wind farm acts and connected two buses on Iraqi system. Because low-frequency monitoring needs accurate fast, main objective propose novel online sy...

—Efficient power system stability monitoring plays a vital role in recent electric grid technologies. It supports operators at control centers to reduce overloading on weak elements and prevent from collapse. In this paper Phasor Measurement Units (PMUs) technology has been used for real-time measurements that can obtain fast accurate data samples the network. The responses during steady state ...

In this paper, an efficient and comprehensive hybrid intelligent technique for the optimal placement of phasor measurement units (PMUs) is proposed to minimize the number of PMU installation subjected to full network observability. Three main purposes of PMUs output synchronous measurements are monitoring, control, and protection of power system. We have combined Binary Imperialistic Competitio...

This paper presents a methodology using Gravitational Search Algorithm for optimal placement of Phasor Measurement Units (PMUs) in order to achieve complete observability of the power system. The objective of proposed algorithm is to minimize the total number of PMUs at the power system buses, which in turn minimize installation cost of the PMUs. In this algorithm, the searcher agents are colle...

This paper deals with an improved use of phasor measurements. In particular, the paper focuses on the development of a technique for estimation of generator rotor angle and speed, based on phasor measurement units, for transient stability assessment and control in real-time. Two multilayered feed-forward artificial neural networks are used for this purpose. One for the estimation of rotor angle...
