A flexible stochastic PV hosting capacity framework considering network over-voltage tolerance

open access: yesEnergy Reports, 2023
Integration of PV resources in distribution networks has become a world-wide trend. This has been necessitated by the ever-decreasing photovoltaic (PV) technology cost and the need for clean, carbon-emission-free power generation.

Constrained Capacity of Delay-Limited Wireless Transceivers [PDF]

open access: yes, 2009
In this paper we devise an analytical framework for the characterization of wireless transceivers. Subsequently, we utilize the proposed methodology in order to calculate the constrained capacity of the delay-limited wireless transceivers. We demonstrate,

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

open access: yesAdvanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Volt-Var Curve Reactive Power Control Requirements and Risks for Feeders with Distributed Roof-Top Photovoltaic Systems

open access: yesEnergies, 2020
The benefits and risks associated with Volt-Var Curve (VVC) control for management of voltages in electric feeders with distributed, roof-top photovoltaic (PV) can be defined using a stochastic hosting capacity analysis methodology.

Adaptive Two-Stage Stochastic Programming with an Analysis on Capacity Expansion Planning Problem

open access: yesManufacturing & Service Operations Management
Problem definition: Multistage stochastic programming is a well-established framework for sequential decision making under uncertainty by seeking policies that can be dynamically adjusted as uncertainty is realized. Often, for example, because of contractual constraints, such flexible policies are not desirable, and the decision maker may need to ...

Absorptive Capacity and Efficiency: A Comparative Stochastic Frontier Approach Using Sectoral Data [PDF]

open access: yes, 2012
In this paper, we investigate differences in and determinants of technical efficiency across three groups of OECD, Asian and Latin American countries. As technical efficiency determines the capacity with which countries absorb technology produced abroad,

Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

open access: yesAdvanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

A Stochastic Simulation Method for Estimating Vegetation Interception Capacity Based on Mechanical‐Geometric Analysis

open access: yesWater Resources Research
Vegetation interception is a vital ecohydrological process, and the interception capacity is a key parameter to many classical interception models. However, current canopy interception capacity estimation methods largely depend on measured interception ...

Capacity bound analysis of networked TT&C architecture based on stochastic geometry and queuing theory

open access: yesDigital Communications and Networks
As commercial mega-constellations such as SpaceX’s Starlink and Amazon’s Kuiper system rapidly expand, traditional Tracking, Telemetry, and Command (TT&C) architectures encounter unprecedented scalability challenges.
