Evaluating Distributed PV Curtailment Using Quasi-Static Time-Series Simulations

IEEE Open Access Journal of Power and Energy, 2021
By strategically curtailing active power and providing reactive power support, photovoltaic (PV) systems with advanced inverters can mitigate voltage and thermal violations in distribution networks. Quasi-static time-series (QSTS) simulations are increasingly being utilized to study the implementation of these inverter functions as alternatives to ...

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 ...

Predetermined time-step solver for rapid quasi-static time series (QSTS) of distribution systems

2017 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT), 2017
Distribution system analysis with high penetrations of distributed energy resources (DER) requires quasi-static time-series (QSTS) analysis to capture the time-varying and time-dependent aspects of the system, but current QSTS algorithms are prohibitively burdensome and computationally intensive. This paper proposes a novel deviation-based algorithm to
