Time Series Analysis of Rapid GNSS Measurements for Quasi-static and Dynamic Bridge Monitoring
2019Since 1996, GPS and GNSS have been used to measure position and time on large structures, notably long span bridges. Receivers act simultaneously as dynamic deformation sensors. The use of high rate GNSS receivers to generate time displacement series—typically 10 Hz or greater—provides improvements in accuracy through both processing techniques and the

This paper focuses on developing a two-step load disaggregation method for conducting quasi-static time-series analysis using actual distribution feeder data. This can help utilities conduct power flow studies using smart meter measurements to assess the impact of high penetration of distributed energy resources.

2019 IEEE Power & Energy Society General Meeting (PESGM), 2019
This paper presents a data-driven load modeling methodology for distribution system quasi-static time-series (QSTS) simulation considering both diversity and variability characteristics of distribution loads. Based on our previous work in [1]–[2], a variability library and diversity library have been established based on the realistic high-resolution ...

2017 IEEE Power & Energy Society General Meeting, 2017
The response of low voltage networks with high penetration of PV systems to transmission network faults will, in the future, determine the overall power system performance during certain hours of the year. The WECC distributed PV system model (PVD1) is designed to represent small-scale distribution-connected systems.

2017 IEEE 44th Photovoltaic Specialist Conference (PVSC), 2017
The increasing deployment of distribution-connected photovoltaic (DPV) systems requires utilities to complete ever more complex interconnection studies. Relatively simple interconnection study methods worked well for low penetrations of photovoltaic systems, but more complicated quasistatic time-series (QSTS) analysis is required to make better ...

2019 IEEE Power & Energy Society General Meeting (PESGM), 2019
Significant changes in the regulatory environment, coupled with economic viability, has led various electric utilities to consider distributed photovoltaic (PV) systems as an alternative to traditional circuit upgrades. Increased penetration of distributed PV can result in the overload of the distribution system infrastructure, which can lead to ...
