Two-Stage Stochastic Unit Commitment Considering Distribution Perturbation via Contamination Technique

2020 IEEE Power & Energy Society General Meeting (PESGM), 2020
Stochastic unit commitment (SUC) is deemed as an efficient operational strategy to tackle with the uncertainty in power system. However, in order to implement SUC, a predetermined probability distribution function (PDF) P or finite scenarios for uncertain parameters is often required, whose true pattern is hard to obtain in real world due to various ...

Localization in wireless sensor networks by constrained simultaneous perturbation stochastic approximation technique

2012 6th International Conference on Signal Processing and Communication Systems, 2012
Localization of sensor networks poses an immense challenge and is considered as a hot research topic in recent days. To address the accuracy on localization this paper proposes constrained simultaneous perturbation stochastic approximation (SPSA) based localization techniques for wireless sensor networks.

Stochastic small perturbation based simulation technique for solving isotropic elastostatics equations

Monte Carlo Methods and Applications, 2015
Abstract The paper deals with a stochastic analysis of random displacements governed by isotropic elasticity equations. The elasticity constants are assumed to be random fields with gaussian distribution. Under the assumption of small fluctuations of elasticity constants but not ignoring their distribution and correlation structure, we ...

Simple analytical solution for multiplicative nonlinear stochastic differential equations by a perturbation technique

Physical Review A, 1986
A simple convergent and analytical solution valid for the whole time range for the stochastic Verhulst equation is obtained by treating the strength of the external Gaussian white noise as a perturbation without using the existing approach where the moments are expressed by means of an integral representation.

Razumikhin Technique and BIBO Stability of Stochastic Delay Systems with Nonlinear Perturbations

Advanced Materials Research, 2013
The problem of mean square bounded-input-bounded-output (BIBO) stability for the stochastic delay systems with nonlinear perturbations is investigated in this paper. Using the Razumikhin technique combined with comparison principle, several novel BIBO mean square stability criteria are established.

The development of stochastic space transformation and diagrammatic perturbation techniques in subsurface hydrology

Stochastic Hydrology and Hydraulics, 1993
The space transformation method is applied to stochastic partial differential equations whose coefficients are random functions of space and/or time. Such equations constitute an integral part of groundwater flow and solute transport. A perturbation analysis based on Feynman- diagram expansions is proposed.

Comparisons between WHEP and Homotopy Perturbation Techniques in Solving Stochastic Cubic Oscillatory Problems

AIP Conference Proceedings, 2009
In this paper, nonlinear oscillators under cubic nonlinearity with stochastic inputs are considered. Two techniques are used to introduce approximate solutions, mainly; the Wiener‐Hermite expansion and perturbation (WHEP) technique and the homotopy perturbation method (HPM).

A stochastic optimization method based technique for finding out reaction paths in noble gas clusters perturbed by alkali metal ions

Chemical Physics, 2010
Abstract In this paper we explore the possibility of using stochastic optimizers, namely simulated annealing (SA) in locating critical points (global minima, local minima and first order saddle points) in Argon noble gas clusters perturbed by alkali metal ions namely sodium and potassium.

Moored dock under random waves: a stochastic perturbation and linearization technique

2006
Aim of this paper is to predict the motion of a dock moored by a couple of cables in irregular waves. Wave forces, of random nature, are determined by a modified Morison equation. The nonlinear effects of the loads and of the cables governing equations are taken into account.
