Abstract

Accurate Frequency Response Estimation (FRE) is critical to reliability risk management of large power system disturbances. This letter proposes a measurement-driven approach for FRE by calculating the second derivative of frequency from synchrophasor data. Compared with conventional methods, the proposed method has major advantages of low computational burden and high accuracy, which makes it appropriate for real-time FRE in bulk power systems. The effectiveness of this method is validated with actual synchrophasor data on 96 confirmed historical power system disturbances in the U.S. eastern interconnection.

Machine Committee Framework for Power Grid Disturbances Analysis Using Synchrophasors Data

Journal Article Niu, Haoran ; Omitaomu, Olufemi ; Cao, Qing - Smart Cities

Events detection is a key challenge in power grid frequency disturbances analysis. Accurate detection of events is crucial for situational awareness of the power system. In this paper, we study the problem of events detection in power grid frequency disturbance analysis using synchrophasors data streams. Current events detection approaches for power grid rely on individual detection algorithm. This study integrates some of the existing detection algorithms using the concept of machine committee to develop improved detection approaches for grid disturbance analysis. Specifically, we propose two algorithms—an Event Detection Machine Committee (EDMC) algorithm and a Change-Point Detection Machine Committee (CPDMC) algorithm.more »« less

Demonstration of a Novel Synchrophasor-based Situational Awareness System: Wide Area Power System Visualization, On-line Event Replay and Early Warning of Grid Problems

Technical Report Rosso, A.

Since the large North Eastern power system blackout on August 14, 2003, U.S. electric utilities have spent lot of effort on preventing power system cascading outages. Two of the main causes of the August 14, 2003 blackout were inadequate situational awareness and inadequate operator training In addition to the enhancements of the infrastructure of the interconnected power systems, more research and development of advanced power system applications are required for improving the wide-area security monitoring, operation and planning in order to prevent large- scale cascading outages of interconnected power systems. It is critically important for improving the wide-area situation awarenessmore »« less

Frequency Response Assessment and Improvement of Three Major North American Interconnections due to High Penetrations of Photovoltaic Generation

Technical Report Liu, Yilu

As photovoltaic (PV) generation penetration increases, the inertial and primary frequency response of North American electric grids after a generation loss disturbance will decrease. This change could negatively influence North American power grids frequency stability. This project produced a series of high PV penetration models from detailed, validated base models of all three U.S. interconnections (Eastern Interconnection, Western Electricity Coordinating Council, and Electric Reliability Council of Texas) so that the effects of increased PV generation on their frequency responses can be fully quantified. Mitigation strategies were also developed and validated using both software and hardware test beds. Before the developmentmore »« less

Fast Parallel Stochastic Subspace Algorithms for Large-Scale Ambient Oscillation Monitoring

Journal Article Wu, Tianying ; Venkatasubramanian, Vaithianathan Mani ; Pothen, Alex - IEEE Transactions on Smart Grid

With the installation of synchrophasors widely across the power grid, measurement-based oscillation monitoring algorithms are becoming increasingly useful in identifying the real-time oscillatory modal properties in power systems. When the number of phasor measurement unit (PMU) channels grows, the computational time of many PMU data based algorithms is dominated by the computational burden in processing large-scale dense matrices. In order to overcome this limitation, this paper presents new formulations and computational strategies for speeding up an ambient oscillation monitoring algorithm, namely, stochastic subspace identification (SSI). Based on previous work, two fast singular value decomposition (SVD) approaches are first applied tomore »« less

Detection of Synchrophasor False Data Injection Attack using Feature Interactive Network

Journal Article Qiu, Wei ; Tang, Qiu ; Zhu, Kunzhi ; ... - IEEE Transactions on Smart Grid

The synchrophasor data recorded by Phasor Measurement Units (PMUs) plays an increasingly critical role in the regulation and situational awareness of power systems. However, the widely installed PMUs are vulnerable to multiple malicious attacks from cyber hackers during data transmission and storage. To address this problem, a Modified Ensemble Empirical Mode Decomposition (MEEMD) is proposed first to extract the intrinsic mode functions of each Synchrophasor Data Attacks (SDA). The frequency-based adaptive screening criterion embedded in MEEMD is used to eliminate the false intrinsic mode functions. Next, a Multivariate Convolutional Neural Network (MCNN) is proposed to identify multiple SDA by utilizingmore »« less
