Interval Power Flow Analysis Considering Interval Output of Wind Farms through Affine Arithmetic and Optimizing-Scenarios Method

open access: yesEnergies, 2018
Wind power belongs to sustainable and clean energy sources which play a vital role of reducing environment pollution and addressing energy crisis. However, wind power outputs are quite difficult to predict because they are derived from wind speeds, which

Towards Verification of Uncertain Cyber-Physical Systems [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2017
Cyber-Physical Systems (CPS) pose new challenges to verification and validation that go beyond the proof of functional correctness based on high-level models. Particular challenges are, in particular for formal methods, its heterogeneity and scalability.

Approximate vertex enumeration

open access: yesJournal of Computational Geometry, 2023
The problem to compute the vertices of a polytope given by affine inequalities is called vertex enumeration. The inverse problem, which is equivalent by polarity, is called the convex hull problem.

An Affine Arithmetic-Based Model of Interval Power Flow With the Correlated Uncertainties in Distribution System

open access: yesIEEE Access, 2020
An interval power flow (IPF) method that considers the interval correlations of input random variables is proposed to improve the calculation accuracy of IPF, i.e., as correlated distributed generations (DGs) and some correlated DGs-loads are integrated ...
