This paper describes a multiple time interval (“multi-interval”) parameter estimation method. The multi-interval parameter estimation method estimates a parameter from a new multi-interval prediction error polynomial that can simultaneously consider multiple time intervals. The root of the multi-interval prediction error polynomial includes the effect on each time interval, and the important mo...

The recent advancement of synchrophasor measurements technology in the conventional power grid can monitor and control state variables network very accurately at a high sampling rate real-time. complete observability system states be achieved through Phasor Measurement Unit (PMU). inclusion zero injection bus (ZIB) optimized total number PMU requirements for observation network. communication c...

The practical implementation of phasor measurement unit (PMU)-based fault location in high-voltage overhead lines presents a number difficulties including the significant impact DC components current wave-form and residual magnetization transformer. Synchrophasor technology was only meant to capture steady states electromechanical transients. issues mentioned above indicate need for changes syn...

Abstract Accurate acquisition of transmission line parameters is the basis for grid condition monitoring and data analysis, which great significance safe economic operation grid. With widespread use phasor measurement unit (PMU) technology, wideband information in can be exploited, broadens new direction parameter identification. In this paper, a method proposed to identify frequency based on i...

The phasor Measurement Unit is a modern tracking tool mounted on network to track and manage power systems. PMU accurate and time-synchronized device that gives voltage measurements in nodes current connected to those where the installed.

<span>This paper makes a contribution to the field of fault location finding in new way that helps improvement grid reliability. This proposes study-based approach for allocation and type classification uses study voltage current frequency during abnormal condition. Although, ideally are same condition they may differ from each other. difference is separately measured by phasor measuremen...

Series of blackouts encountered in recent years in power system have been occurred because either of voltage or angle instability or both together was not detected within time and progressive voltage or angle instability further degraded the system condition, because of increase in loading. This paper presents the real-time assessment methodology of voltage stability using Phasor Measurement Un...

This research examines an admissible search algorithm-dependent A-star strategy and takes into account redundancy cost/benefit analysis under normal operating conditions. The goal is to allocate a phasor measurement unit (PMU) for maximal observability of the interconnected power network. To determine fewest number PMU required make connected network totally observable using analysis, approach ...

The accuracy of distribution system state estimation (DDSE) is reduced when phasor measurement unit (PMU) measurements contain outliers because cyber attacks or global positioning spoofing attacks. Therefore, to enhance the robustness DDSE outliers, approximate target Metropolis-Hastings (MH) sampling, and judge prediction long short-term memory (LSTM) network, this paper proposes an outlier re...
