Abstract

Data from Phasor Measurement Units (PMUs) inform powerful diagnostic tools that can help avert catastrophic failures in the power grid. Because of this, PMU measurement errors are particularly problematic, and it is critical to understand their impact. However, there is limited understanding of how much the PMU measurement errors affect the performance of various synchrophasor-based applications, and thus the ability of these applications to fulfill the users' requirements effectively is also unclear. This paper examines internal and external factors contributing to PMU phase angle and frequency measurement errors. A generic method is proposed to evaluate the impact of measurement errors on application performance. The impact of measurement errors on several synchrophasor-based Wide Area Monitoring System (WAMS) applications are analyzed as examples. These applications include power system disturbance location, oscillation detection, islanding detection, and dynamic line rating. The analysis demonstrated that the proposed method can be used to quantify the measurement error impact and analyze the performance degradation of these applications due to the measurement error. It also reveals that the impact of measurement error depends on the type, algorithm, and parameters of applications.

Impact of Measurement Error on Synchrophasor Applications

Technical Report Liu, Yilu ; Gracia, Jose R. ; Ewing, Paul D. ; ...

Phasor measurement units (PMUs), a type of synchrophasor, are powerful diagnostic tools that can help avert catastrophic failures in the power grid. Because of this, PMU measurement errors are particularly worrisome. This report examines the internal and external factors contributing to PMU phase angle and frequency measurement errors and gives a reasonable explanation for them. It also analyzes the impact of those measurement errors on several synchrophasor applications: event location detection, oscillation detection, islanding detection, and dynamic line rating. The primary finding is that dynamic line rating is more likely to be influenced by measurement error. Other findings include themore »« less

Power system observability and dynamic state estimation for stability monitoring using synchrophasor measurements

Journal Article Sun, Kai ; Qi, Junjian ; Kang, Wei - Control Engineering Practice

Growing penetration of intermittent resources such as renewable generations increases the risk of instability in a power grid. This paper introduces the concept of observability and its computational algorithms for a power grid monitored by the wide-area measurement system (WAMS) based on synchrophasors, e.g. phasor measurement units (PMUs). The goal is to estimate real-time states of generators, especially for potentially unstable trajectories, the information that is critical for the detection of rotor angle instability of the grid. The paper studies the number and siting of synchrophasors in a power grid so that the state of the system can be accuratelymore »« less

Pre-commercial Demonstration of Direct Non-iterative State Estimator for Operational Use of Synchrophasor Management Systems

Technical Report Lelic, Muhidin ; Avramovic, Bozidar ; Jiang, Tony ; ...

The objective of this project was to demonstrate functionality and performance of a Direct Non-iterative State Estimator (DNSE) integrated with NYPA’s Energy Management System (EMS) and with enhanced Real Time Dynamics Monitoring System (RTDMS) synchrophasor platform from Electric Power Group (EPG). DNSE is designed to overcome a major obstacle to operational use of Synchro-Phasor Management Systems (SPMS) by providing to synchrophasor management systems (SPMS) applications a consistent and a complete synchrophasor data foundation in the same way that a traditional EMS State Estimator (SE) provides to EMS applications. Specifically, DNSE is designed to use synchrophasor measurements collected by a centralmore »« less
Resiliency-Driven Proactive Distribution System Reconfiguration With Synchrophasor Data

Journal Article Pandey, Shikhar ; Chanda, Sayonsom ; Srivastava, Anurag K. ; ... - IEEE Transactions on Power Systems

Measuring and enabling resiliency of electric distribution systems with increasing weather and cyber events are important. Some of the extreme events (e.g. Earthquakes, Hurricanes) and associated paths are predicted and monitored closely in advance and allow to take pre-event proactive control actions. The Distribution Phasor Measurement Units (D-PMUs) provide new opportunities and supporting such proactive actions. A synchrophasor based resiliency driven pre-event reconfiguration can ensure minimizing impact of the expected event on the power distribution system and associated performance. However, the D-PMUs will also face challenges in terms of data quality similar to the transmission PMUs. The focus of thismore »« less
