Advances in OpenDSS smart inverter modelling for quasi-static time-series simulations
CIRED - Open Access Proceedings Journal, 2020 The fleet of smart distributed energy resource (DER) inverters is expected to grow rapidly as a result of growing DER penetration levels and requirements in interconnection standards/rules such as IEEE Std 1547-2018. Smart inverters have the potential to help to maintain and/or enhance grid safety, reliability and customer affordability.

Quasi-static crack propagation by Griffith's criterion [PDF]
, 2008 We consider the propagation of a crack in a brittle material along a prescribed crack path and define a quasi-static evolution by means of stationary points of the free energy. We show that this evolution satisfies Griffith's criterion in a suitable form

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,

Static behaviour of functionally graded sandwich beams using a quasi-3D theory [PDF]
, 2015 This paper presents static behaviour of functionally graded (FG) sandwich beams by using a quasi-3D theory, which includes both shear deformation and thickness stretching effects. Various symmetric and non-symmetric sandwich beams with FG material in 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

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.

Extreme Wave Loading on a Vertical Circular Cylinder
Applied Sciences, 2023 Extreme wave loading on a marine structure, consisting of a quasi-static and a dynamically slamming component, often drives the design of such a structure. Their accurate predictions remain challenging tasks. This paper examines the slamming contribution
