Monte Carlo Based Method for Parallelizing Quasi-Static Time-Series Power System Simulations [PDF]
2018 IEEE International Conference on Probabilistic Methods Applied to Power Systems (PMAPS), 2018 Both commercial and open source power system simulators run quasi-static time-series (QSTS) simulations sequentially. For yearlong high-resolution load profiles this sequential execution of load flows incurs long computation times. Parallelizing QSTS simulations on multiple processors is one possible way to reduce the computation time.

Implementation of Temporal Parallelization for Rapid Quasi-Static Time-Series (QSTS) Simulations
2019 IEEE 46th Photovoltaic Specialists Conference (PVSC), 2019 Quasi-static time-series (QSTS) analysis of distribution systems can provide critical information about the potential impacts of high penetrations of distributed and renewable resources, like solar photovoltaic systems. However, running high-resolution yearlong QSTS simulations of large distribution feeders can be prohibitively burdensome due to long ...

Fast Quasi-Static Time-Series (QSTS) for yearlong PV impact studies using vector quantization
Solar Energy, 2018 Abstract The rapidly growing penetration levels of distributed photovoltaic (PV) systems requires more comprehensive studies to understand their impact on distribution feeders. IEEE P.1547 highlights the need for Quasi-Static Time Series (QSTS) simulation in conducting distribution impact studies for distributed resource interconnection.

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.

Quasi-Static Time-Series Power Flow Solution for Islanded and Unbalanced Three-Phase Microgrids [PDF]
IEEE Open Access Journal of Power and Energy, 2021 Recent advances in inverter-based distributed energy resources (DERs) allow microgrids to operate in grid-connected and islanded modes with ease. However, determining a steady-state load flow solution of a real-world unbalanced and islanded three-phase microgrid remains a challenge.

Iterated-sums signature, quasi-symmetric functions and time series analysis [PDF]
, 2020 We survey and extend results on a recently defined character on the quasi-shuffle algebra. This character, termed iterated-sums signature, appears in the context of time series analysis and originates from a problem in dynamic time warping. Algebraically,
