Data-Driven Distribution System Load Modeling for Quasi-Static Time-Series Simulation
IEEE Transactions on Smart Grid, 2020 This paper presents a data-driven distribution system load modeling methodology targeting quasi-static time-series (QSTS) simulation. The proposed methodology is appropriate for modeling down to the level of the customer transformer, and it has three main features: 1) both load pattern diversity and intra-second load variability are considered, 2) the ...

IEEE Transactions on Sustainable Energy, 2019 Understanding the impact of distributed photovoltaic (PV) resources on various elements of the distribution feeder is imperative for their cost effective integration. A year-long quasi-static time series (QSTS) simulation at 1-second granularity is often necessary to fully study these impacts.
